RELATED APPLICATIONS

[1] This application claims priority to U.S. Provisional Application No. 62/570519, filed October 10, 2017, and U.S. Application No. 16/016709, filed June 25, 2018, the contents of which are incorporated herein by reference in their entirety.

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

[2] The present invention relates to drilling and tripping systems and processes for drilling and tripping drill pipe and casing in relation to drilling rig operations. In particular, the present invention relates to pipe and casing running sequences on a drilling rig.

BACKGROUND OF THE INVENTION

[3] When searching for oil, gas and geothermal energy, drilling operations are carried out to create pits or wells in the surface of the earth. Modern drilling rigs can carry out not only drilling, but also tripping pipes for simultaneous drilling and tripping operations.

[4] Conventional drilling involves placing the drill bit at the bottom of the well. The bottom hole assembly is located directly above the drill bit where the directional sensors and communication equipment, batteries, downhole motors and stabilizing equipment are located to help guide the drill bit to the desired subterranean target area. A set of drill collars is positioned above the bottomhole assembly to provide an incompressible source of mass to assist in breaking up the formation with the drill bit. The heavy wall drill pipe is positioned above the drill collars for safety. The remainder of the drill string is primarily drill pipe designed for live operation. Each drill pipe is approximately 30 feet long, but sections may vary by design. It is common to store sections of drill pipe as "two-tube" (two connected sections) or "tri-tube" (three connected sections) or even "quad" (four connected sections). The term "stand" refers to connected sections of drill pipe, drill collar or casing.

[5] When the drill bit wears out or when maintenance, repair, or adjustment of the bottomhole assembly is required, the drill string (drill pipe and other components) is removed from the wellbore and placed on a candlestick. When the entire drill string is pulled out of the well, it is typically disengaged and placed on a stand-up stand in the form of two or three tubes until the drill bit is retrieved and replaced. This process of lifting everything from the barrel and lowering it back into the barrel is known as "trip".

[6] Tripping operations are operations during which no drilling takes place, and thus they are associated with losses (see, for example, US patent application 2017/0234088, 08/17/2017). For a long time, attempts have been made to develop ways to eliminate these operations, or at least speed them up. The lowering of the three-tubes is faster than the lowering of the two-tubes, since in this case there are fewer threaded connections that need to be disconnected and then reconnected. Triple tubes are longer and thus more difficult to handle due to their length and mass, as well as the natural vibrations that occur as they move from place to place. Handling moving pipes by hand on the derrick and at rig floor level can be dangerous.

[7] It is desirable that processes on a running rig run more efficiently and efficiently without sacrificing safety.

[8] Most attempts to automate tubing trips are carried out offshore. However, pipe delivery technologies on offshore rigs can rarely be transferred to onshore rigs due to many differences in economic viability, size, weight and transportation considerations.

[159] The objects and features of the present invention will become more apparent from the following detailed description and the appended claims when read in conjunction with the accompanying drawings, in which like reference numerals designate like elements.

[160] The drawings form part of the present specification and contain illustrative embodiments of the invention, which may be embodied in various forms. It should be understood that in some instances, various aspects of the invention may be shown exaggerated or enlarged in order to facilitate understanding of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[161] The preferred embodiments are best explained with reference to FIGS. 1-145B below with the following general description in mind. The present invention may be better understood in the context of a high-level description of certain embodiments.

[162] According to various aspects of the present invention, sequences for tripping operations are provided, including: (i) running a drill pipe, (ii) pulling a drill pipe, (iii) pulling a drill string with fluid, (iv) pulling a casing stand with liquid, (v) running a casing stand without a casing running tool, (vi) running a drill collar stand; (vii) lifting of the drill collars; (viii) lifting single drill pipe from the catwalk to the center of the well using a top drive, (ix) placing single drill pipe from the center of the well onto the catwalk using a top drive, (x) moving one casing pipe from the catwalk using a tong to (xi) placing one casing from the center of the well onto the catwalk using a casing wrench, (xii) moving the casing off the catwalk using a top drive and casing running tool, (xiii) moving the casing with (xiv) make-up of the drill stand not in the center of the hole, (xv) laying the stand of the drill pipe not in the center of the hole, (xvi) make-up of the stand of the casing not in the center of the hole, (xvii) laying standpipes off-center of the well, (xviii) connecting drill pipes, and (xix) reworking the well. The sequences may be performed in fully automatic mode or in manual mode, and the sequence steps may be the same in either mode. Some sequences may be performed simultaneously, such as, for example, pipe make-up sequences may be performed simultaneously with drilling or tripping sequences.

[163] Various embodiments of a drilling rig system may comprise one or more of the following components:

1) Retractable top drive

2) Pipe feed arm

3) Upper store/candlestick platform

4) Bridge paver

5) Candlestick guide arm

6) Lower stabilizer arm

7) Upper candle holder

8) Intermediate spark plug

9) Lower spark plug retainer

10) Drilling key on the wrench trolley

11) Drilling key on the lever for lowering and raising the key

12) Receiving catwalks

13) Rotary table with wedges

Various components can be used together to perform stand-in, run-in, pull-out, etc. Operations on the drilling rig can be controlled by two workers: a driller and a pipelayer. The driller is primarily responsible for drilling operations in which the drill string is lowered into and out of the wellbore. The pipelayer is primarily responsible for moving the pipe into or out of the center of the well and for making and breaking tool joints. Drilling and pipe tripping operations can be carried out simultaneously. A zone control system or an anti-collision system can be used to prevent components from colliding with each other.

[164] Devices with a control interface, such as joysticks, can allow workers to perform all work and functions on the drilling rig. For example, during one sequence of operations, any number of constituent machines can be controlled simultaneously by one worker through two joysticks. Human-machine interfaces can provide images to the touch screen for control.

[165] FIG. 1 shows an isometric view of an embodiment of a drilling rig system. In FIG. 1 shows a drilling rig 1 with the front end (part of the receiving chute) removed. In its place is a candlestick pad 900 near ground level, projecting above the main box sections of the substructure 2 on the ground. In this position, the candlestick platform 900 is directly below the rack module 300, whereby any tube candles 80 (not shown) located in the rack module 300 will be on the candlestick platform 900. In this configuration, the rack module 300 is located lower on the derrick 10 of the drilling rig 1 than on conventional surface rigs because the stand 80 is not at the level of the rig floor. Additionally, the standpipe 80 must be substantially raised to reach the floor level 6 of the rig.

[166] As will be appreciated from the following description, this arrangement provides many advantages in combination with several other unique components of the high tripping speed drilling rig 1. To get the most benefit, it needs a spacious drilling floor 6 to accommodate connection equipment such as an automatic drill tong, and a bottom stabilizing arm to control the free movement of the string stands being lifted by the retractable top drive and auxiliary lifting mechanism.

[167] FIG. 2 shows a top view of the rack module 300. The center 40 of the pipe pit is located at the front edge of the rig floor 6 and extends downward. The intermediate latch 430 candles is located next to the floor 6 of the drilling rig and is centered relative to the center 40 of the hole for pipe extension. The candle transfer position 50 is located on the candle holder platform 900, protrudes vertically upwards and is not blocked by any other structure below the rack module 300. The lower candle latch 440 is located on the candle holder platform 900 and can be centered relative to the candle transfer position 50. In this embodiment, the position 50 of the transmission of the candle is located in front of the center 30 of the borehole and the center 40 of the pit for building pipes and aligned with them.

[183] (I) DRILL RIP SEQUENCE

[184] The initial equipment configuration for the drill pipe running sequence is as follows:

The top drive 200 is in the down position on the hole center axis 30 and the elevator is closed around the drill pipe stand 80 .

The stand 80 of the drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

One drill stand 80 is raised by the pipe feed arm 500 and the lower stabilizing arm 800 from the stand transfer position 50 to the level of the projection above the extension hole 40 with the elevator facing the top drive and the drilling floor in the ready position.

The candle transfer position is empty; both the upper spark plug retainer and the lower spark plug retainer are open and retracted.

Bridge stacker 350 and candlestick guide arms 950 are empty and on their way to lift a new drill stand from the top magazine.

[185] The sequence of running the drill pipe includes the following steps.

[186] Step 1: releasing the drill string and moving the top drive. The top drive elevator is opened to release the protruding part of the drill string and the top drive is raised to the top stop in the derrick 10. As shown in FIG. 17B, the top drive elevator is disconnected from the drill string extension. As shown in FIG. 17A, the top drive 200 is raised towards the top of the mast 10.

[187] Step 2: moving the candle to the center of the well. The tubing lever 500 and lower stabilizing arm 800 move the tubular stand 80 from the standby position on the rig floor 6 to the center 30 of the well as shown in FIG. 18A and 18B. The selected automatic wrench 760 is moved to the center of the hole to make up the connection.

[188] Stage 3: rise of a new candle. The bridge stacker 350 and candlestick guide arm 950 lift the candlestick 80 off the candlestick platform 900 as shown in FIG. 19A and 19B.

[189] Step 4: moving the new spark plug to the spark transfer position. The bridge stacker 350 and spark plug guide arm 950 move the new spark plug and place it in the spark transfer position 50 as shown in FIG. 20A and 20B. At the upper spark plug retainer 420 and the lower spark plug retainer 440, their clamps 408 interlock to hold the new spark plug 81 in the spark transfer position 50. See fig. 20A and 20B. An oiler installed in the spark plug transfer position 50 flushes and lubricates the nipple end of the spark plug 81. See FIG. 20C. Bridge stacker 350 and candlestick guide arm 950 return to upper magazine 310 to lift the next candle.

[190] Step 5: Move the new stand to the center of the well and make up the connection to the drill string. The top drive is moved away from the hole center 30 along its path up the derrick 10. The tong and insertion guide are engaged with the protruding portion of the drill string at the hole center 30 to assist in driving the next stand. The pipe feed lever 500 and the lower stabilizing arm 800 lift the next candle from the candle transfer position 50 and move it to the center 30 of the well. See fig. 21A and 21B. The pipe feed arm 500 and bottom stabilizer arm 800 then lower the new plug and continue to move them approximately 2 m/6 ft past the pipe to make room for the top drive elevator. The lower stabilizing arm 800 is released and moved away from the center 30 of the well. The automatic drill tong 760 is rotated and torque is applied to make up the connection between the new stand and the drill string.

[191] Step 6: Putting the top drive elevator on the drill string. When the top drive is at the proper height, the top drive is moved to the center 30 of the well and the elevator is closed around the drill string. See fig. 22A and 22B. The pipe feed arm 500 is opened and moved away from the center of the well. The pipe feed arm 500 and the lower stabilizing arm 800 are moved to lift the next plug at the plug transfer position 50. The automatic drill key 760 is released and returned to the standby position relative to the floor 6 of the drilling rig.

[192] Step 7: opening slips and running the drill string. The top drive and winch are raised to lift the mass of the drill string, and the wedges on the spider are opened. The drill string is then lowered into the wellbore by means of a top drive. See fig. 23. The pipe feed arm 500 and the lower stabilizer arm 800 are engaged with the new spark plug at the spark plug transfer position 50. The upper and lower spark plug retainers 420 and 440 are released and moved away from the new spark plug. The new stand is raised (approximately 9 m/30 ft) by the tubing arm 500 and guided by the lower stabilizing arm to the rig floor 6 . The top plug sleeve can be lubricated via the tubing arm 500, if desired. After the top drive drill string has been moved into the wellbore, the spider slips are set so that the drill string protrudes approximately 1.2 m.

[193] (II) DRILL PIPE LIFT SEQUENCE

[194] The initial equipment configuration for the drill pipe hauling sequence is as follows:

The top drive 200 is in the down position on the hole center axis 30 and the elevator is closed around the drill pipe stand 80 .

The stand 80 of the drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

The pipe feed arm 500 and the lower stabilizing arm 800 are open at the plug transfer position 50 and are at the start of movement towards the rig floor 6 .

The drill stand is in position 50 of the stand transfer; the upper spark plug retainer 420 and the lower spark plug retainer 440 clamp the spark plug.

The bridge stacker 350 and candlestick guide arms 950 are empty and are in their path from the upper stacker to carry the drill pipe at the stand transfer position 50.

[195] The sequence of lifting the drill pipe includes the following steps.

[196] Step 1: open the slips and lift the drill string with the top drive. The spider slips are opened and the drill string is raised by the top drive and winch to the top stop in the derrick 10 as shown in FIG. 24A, leaving approximately 1.2 m of the drill string protruding after breakout. The spider slips are installed and the mass of the drill string is seated on the slips. The pipe feed arm 500 begins to move from the plug transfer position 50 to a position above the rig floor. The drill tong 760 is moved to the center 30 of the well to engage with the drill string.

[197] Step 2: moving the candle from the candle transfer position to the upper magazine. The bridge stacker 350 and the candlestick guide arm 950 are moved towards the spark plug at the spark plug transfer position 50 and their grips and guides are closed. At the upper spark plug latch 420 and the lower spark plug latch 440, their clips 408 open to release the spark plug 81 at the spark plug transfer position 50 and the clips are moved away from the spark plug. The bridge stacker 350 and candlestick guide arm 950 lift the candle and move it to the selected position in the upper magazine 310. See FIG. 25A and 25B.

[198] Step 3: Move the pipe feed arm, lower stabilizer arm, and drill tong to the center of the well. The tong 760 is moved to the center 30 of the well and raised to the proper height to engage the drill string to break out the connection. The pipe feed arm 500 and the lower stabilizing arm 800 are moved to the well center 30 from the spark plug transfer position 50 . The pipe arm 500 is extended and its grip on the drill string below the top drive elevator is closed, as shown in FIG. 26A and 26B.

[199] Step 4: opening the elevator and loosening the connection with a drilling tong. The top drive elevator is opened to release the drill string, and the top drive 200 is moved away from the hole center position to the retracted position. The top drive starts moving back down the tower. The 760 wrench loosens the lock and unscrews the threads between the stand and the drill string so as to leave the protruding part of the drill string on the drill floor. See fig. 27.

[200] Step 5: moving the candle from the center of the well to the transmission position of the candle while lowering the top drive to the protrusion. The top drive is moved away from the borehole center 30 along its path down the derrick 10. The tong is released and moved away from the drill string extension at the borehole center 30 to a ready position on the drilling floor. The pipe feed lever 500 and the lower stabilizing arm 800 lift the disengaged plug in the center 30 of the well, lift it off the protrusion and move it to the plug transfer position 50. See fig. 28A and 28B.

[201] Step 6: Putting the top drive elevator on the drill string and moving the spin-out stand. When the top drive is at the proper height relative to the drill string protrusion, the top drive is moved to the center 30 of the well and the elevator is closed around the drill string. The pipe feed lever 500 and the lower stabilizing arm 800 position the spark plug at the spark transfer position 50 . The upper and lower spark plug retainers 420 and 430 interlock to hold the spark plug. With an oiler installed in the spark plug transfer position, wash and lubricate the spark plug nipple. See fig. 29.

[202] Step 7: Installing the candle on the candlestick by means of the bridge stacker and the candlestick guide arm. The bridge stacker 350 and the candlestick guide arm 950 place the candle on the candlestick in the upper magazine 310. The latches of the upper magazine 310 close around the candle. Bridge stacker 350 and candlestick guide arm 950 are returned to the candle transfer position 50. See fig. 30A and 30B.

[203] (III) LIQUID DRILL STRING LIFT SEQUENCE

[204] The initial configuration of the equipment for lifting with liquid is similar to that described above for lifting the drill pipe.

[205] The liquid lifting sequence is very similar to the drill pipe lifting sequence described above. In fact, steps 1-4 and 6-7 are identical.

[206] Step 5: extending the anti-spill device to the center of the well and lifting the spin-off stand from the protruding part of the drill string. The drill tong is released and moved away from the protruding part of the drill string in the center 30 of the well to the standby position on the drilling floor. See fig. 31A. The anti-spill device is extended to the center of the well and closed on the uncoupled connection. The pipe feed arm 500 and the lower stabilizing arm 800 lift the disengaged plug in the center 30 of the well and lift it off the protruding portion. See fig. 31b. The liquid in the candle is captured by means of an anti-spill device. The anti-spill device is opened and moved away from the center of the well to its standby position. The pipe feed lever 500 and the lower stabilizing lever 800 move the unscrewed plug to the plug transfer position 50.

[207] (IV) LIQUID CASING STANDER RUN SEQUENCE

[208] The sequence of lifting the casing pipe with liquid is similar to the sequence of lifting the candlesticks with liquid.

[209] (V) CASING STANDER SEQUENCE WITHOUT A CASING TOOL

[210] The initial equipment configuration for the casing string running sequence is similar to that described above for running the drill pipe.

[211] The casing running sequence is very similar to the drill pipe running sequence described above. In fact, steps 1-4 and 6-7 are identical.

[212] Step 5: Make-up the connection with the casing tong on the tong pull arm. See fig. 32A and 32B.

[213] (VI) SEQUENCE OF RUNTING THE STANDS OF THE DRILL CHANGES

[214] The initial equipment configuration for the drill collar running sequence is as follows:

The top drive 200 is in the down position on the center hole axis 30 and the elevator is closed around the protruding portion of the drill collar.

The stand 80 of the drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

One drill collar stand is in the stand transfer position 50, held in this position by the closed clamps of the top and bottom stand retainers 420 and 440.

The lower stabilizer arm 800 is empty and ready to lift the drill collar stand from the transfer stand position.

The pipe feed lever 500 is located high, out of the way, as it is not used in the drill collar stand sequence.

Bridge stacker 350 and candlestick guide arms 950 are empty and on their way to lift a new drill collar stand from the top magazine.

[215] The drill collar running sequence includes the following steps.

[216] Step 1: opening the top drive elevator and moving the top drive to the top stop. The top drive elevator is opened to release the protruding portion of the drill collar, and the top drive is raised to the top stop in the derrick 10. Meanwhile, one drill collar stand is in the stand transfer position 50, held in that position by the closed clamps of the top and bottom detents 420 and 440 candles. See fig. 33A and 33B.

[217] Step 2: tilting the drill collar stand to the drill collar moving position. The upper stand 420 is extended significantly, and the lower stand 440 is extended just enough to tilt the drill collar as shown in FIG. 34. The lower pin end of the drill collar stand remains in the passage 912 of the stand 900 (see FIG. 35D) and the drill collar stand is tilted to a drill collar travel position in which the box end is tilted toward the derrick 10. The lower stabilizing arm 800 are pushed to the side of the stand of the drill collars.

[218] Step 3: Putting the top drive elevator on the tilted candle. The top drive is at the correct height and in the extended position (center of the hole) so that the elevator links can be moved towards the drill collar stand. The top drive elevator is closed on a candle. See fig. 35A. The lower stabilizing arm 800 locks its guide cone on the tilted drill collar stand. See fig. 35b. The drill tong 760 is moved to the center 30 of the well on a wrench trolley and its guide is closed for insertion. See fig. 35b.

[219] Step 4: Raise the candle from the level of the candlestick to the floor of the rig. The upper and lower calipers 420 and 440 of the caliper are released to release the tilted caliper of the drill collars. The drill collar stand is raised (approximately 9 m/30 ft) by the top drive 200 and winch while being guided by the bottom stabilizing arm 800. The elevator links are allowed to move freely towards the center of the hole. When the drill collar stand is hung over the protrusion, the lower stabilizing arm 800 guides the lower end of the stand into the center 30 of the hole. See fig. 36. The lower stabilizer arm 800 closes its centralizer when the drill collar stand is close to vertical above the protrusion height.

[220] Step 5: inserting a stand of drill collars and making up the connection. The top drive is located in the center of the hole 30 with a drill collar stand. The guide for inserting the drilling key is closed to facilitate insertion. The top drive 200 then lowers a new drill collar stand to insert the stand into the string. See fig. 37A. The lower stabilizing arm 800 is released and moved away from the center 30 of the well. The automatic drill tong 760 is rotated and torque is applied to make up the connection between the new drill collar stand and the drill collar string. See fig. 37b. The drill key is pushed into the ready position.

[221] Step 6: opening slips and running the drill string. The top drive and winch are raised to lift the weight of the drill collar, and the wedges on the spider are opened. The drill collar string is then lowered into the wellbore by means of a top drive. See fig. 38.

[222] Step 7: Lifting a new drill collar stand from the stand. The bridge stacker 350 and the candlestick guide arm 950 raise the drill collar stand from the selected position in the candlestick 900. See FIG. 39A and 39B.

[223] Step 8: moving the candle to the transmission position of the candle. The bridge stacker 350 and the candlestick guide arm 950 move the drill collar stand to the stand transfer position 50 . At the top and bottom retainers 420 and 440, the spark plugs interlock their clips to hold the spark plug. See fig. 40A and 40B. With an oiler installed in the position of the transfer of the candle, the nipple is washed and lubricated. Bridge stacker 350 and candlestick guide arm 950 are moved to lift another drill collar stand from another selected position in candlestick 900 and upper magazine 310.

[224] (VII) SEQUENCE OF LIFTING STANDS OF DRILL CHANGES

[225] The initial equipment configuration for the drill collar lifting sequence is as follows:

The top drive 200 is in the down position on the center hole axis 30 and the elevator is closed around the protruding portion of the drill collar.

The stand 80 of the drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

One drill collar stand is in the stand transfer position 50, held in this position by the closed clamps of the top and bottom stand retainers 420 and 440.

The pipe feed lever 500 is located high, out of the way, as it is not used in the drill collar stand sequence.

The bridge stacker 350 and candlestick guide arms 950 are empty and are on their way from the top magazine 310 to lift the spin-out stand of the drill collar at the stand transfer position 50.

[226] The drill collar lifting sequence includes the following steps.

[227] Step 1: opening slips and lifting the drill collar string. With the help of a top drive and a winch, the mass of the drill collar string is received and the wedges are opened on the spider in the floor of the drilling rig. Lifting is stopped when the column is raised to the level of the protrusion height. See fig. 41A and 41B.

[228] Step 2: moving the candle from the candle transfer position to the candlestick/top magazine. The bridge stacker 350 and the standoff guide arm 950 engage with the drill collar stand at the stand transfer position 50. The top and bottom retainers 420 and 440 of the spark plug are detached from the spark plug. See fig. 42A and 42B. The bridge stacker 350 and the candlestick guide arm 950 lift and move the drill collar stand into the candlestick/top magazine. The latches of the upper store open when the candle is moved in a row and close behind it.

[229] Step 3: moving the lower stabilizing arm and the drill collar to the drill collar string. Wedges are installed and the mass of the column is removed from the top drive elevator. See fig. 43. The selected tong 760 is moved to the string at the center of the hole and raised to the height of the protrusion. The lower stabilizing arm 800 is moved from the spark plug transfer position to a safe ready position next to the spark plug. The lower stabilizing arm 800 is moved to the center of the well and its guide is closed on the stand.

[230] Step 4: breakout with a tong. The automatic drill tong 760 is rotated and torque is applied to loosen the connection between the new drill collar stand and the drill collar string. See fig. 44. The drilling key is pushed into the ready position.

[231] Step 5: Rise and tilt the candle. The top drive 200 raises the spin-out stand of the drill collars and provides guidance through the lower stabilizing arm 800. See FIG. 45A and 45B.

[232] Step 6: Tilt the spark plug to the spark transfer position. When the stand moves away from the protrusion, the lower stabilizing arm 800 guides the lower end of the drill collar stand while the top drive lowers the stand into the transfer position of the stand in the passage 912 of the stand 900. The top drive links are tilted towards the removal position. The upper and lower calipers 420 and 440 of the stand 420 and 440 extend and clamp the stand of the drill collars. See fig. 46A-46C. The nipple is washed and lubricated.

[233] Step 7: open the elevator. The top drive elevator is released (see FIG. 47) and the links allow the elevator to move freely back to a vertical position under the top drive. The guide cone of the lower stabilizing arm 800 is opened and the arm is moved to the ready position. The top drive is lowered towards the projecting part.

[234] Step 8: tilting the drill collar stand relative to the vertical in the stand transfer position. The upper stand 420 is pushed in significantly, and the lower stand 440 is pushed in just enough to tilt the drill collar relative to the vertical in the stand transfer position. See fig. 48.

[235] Step 9: Move the drill collar stand to the stand/top magazine. The bridge stacker 350 and the standoff guide arm 950 are moved to engage the drill collars in the stand transfer position. The upper and lower calipers 420 and 440 of the caliper are opened to release the calipers of the drill collars. The bridge stacker 350 and the candlestick guide arm 950 move the drill collar stand to the selected position in the candlestick. See fig. 49A and 49B. The latches of the upper store close on the candle. The bridge stacker 350 and candlestick guide arm 950 are disengaged from the candle and returned to the candle transfer position.

[236] Step 10: engaging the top drive elevator with the drill collar extension. See fig. fifty.

[237] (VIII) SEQUENCE OF LIFTING SINGLE PIPE FROM THE PICKUP WITH THE TOP DRIVE

[238] The initial equipment configuration for the lifting sequence of single tubes from the catwalks is as follows:

The top drive 200 is in the down position on the well center axis 30 and the elevator is closed around the protruding part of the pipe.

The drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

The conveyor of the mechanized receiving catwalks is loaded with pipes (cleaned and lubricated).

The platform of the mechanized receiving walkways is empty and is in the loading position.

[239] The sequence of lifting the single tubes from the receiving catwalks includes the following steps.

[240] Step 1: loading the pipe onto the platform of mechanized receiving walkways. A conveyor is used to load one pipe onto the platform of the mechanized receiving walkways 600. See FIG. 51.

[241] Step 2: Move the catwalk to the rig floor. Platform of the mechanized receiving walkways 600. See fig. 52A-52C.

[242] Step 3: Opening the elevator and raising to the hoist position. The top drive elevator 200 is opened (see FIG. 53) and the links are tilted back so that the elevator can move away from the pipe lock. The top drive is lifted to the lifting position 60 on the receiving walkways.

[243] Step 4: ejection of the pipe. The pipe pusher of the mechanized receiving catwalks 600 pushes the pipe up from the platform to the position of the pipe for putting on. The top drive links are tilted forward to move the elevator towards the pipe, and the elevator is slipped onto the pipe. See fig. 54A and 54B.

[244] Step 5: tightening the pipe. The pipe is tightened by raising the top drive 200 such that the socket end of the pipe is raised by the elevator. As the top drive rises, the lower sleeve end of the pipe moves upward from the platform of the mechanized catwalk 600. Before the lower sleeve end of the pipe leaves the end of the platform of the mechanized catwalk 600, the lower stabilizing arm 800 is extended and its cone is closed to guide the pipe. As the pipe approaches the vertical position, the centralizers of the lower stabilizing arm 800 close on the pipe. See fig. 55.

[245] Step 6: directing the pipe to the center of the well. The tong 760 is moved towards the protrusion while the top drive 200 continues to lift the pipe. When the pin end is raised above the protrusion, the lower stabilizing arm 800 guides the pipe into the center 30 of the well. The platform of the receiving walkways is moved to the side and down into position for loading the next pipe. See fig. 57. In an alternative embodiment that uses a tong handle, a tong on a tong carriage can be used for the connection. See fig. 56.

[246] Step 7: pipe insertion. The guide for inserting the drilling key is closed over the protruding part. The top drive is lowered to insert the pipe into the insertion guide. When the pipe is in the insertion guide, the lower stabilizing arm 800 is released and retracted. The top drive is additionally lowered to insert the pipe into the protruding part.

[247] Step 8: make-up connection. Drilling key 760 screw the pipe for threaded connection of the nipple end of the pipe with the box end of the protruding part. The drill key 760 then applies a tightening torque to make up the lock. See fig. 58.

[248] Step 9: running the drill string. The drilling key is moved to its standby position. Raise the mass of the drill string using a top drive/winch. Open the wedges in the spider. The drill string is lowered into the wellbore to the protrusion height. Install the wedges in the spider. See fig. 59.

[249] (IX) SEQUENCE OF LAYING SINGLE PIPE ON THE PICKUP WITH THE TOP DRIVE

[250] The initial configuration of the equipment for the sequence of laying single-tubes from the center of the well to the receiving catwalks is as follows:

The top drive 200 is in the down position on the well center axis 30 and the elevator is closed around the protruding portion of the pipe.

The drill pipe is suspended in a spider in the floor 6 of the drilling rig so that approximately 1.2 m/4 ft of the drill string protrudes from the floor 6 of the drilling rig.

The conveyor of mechanized receiving walkways is unloaded and ready to receive pipes.

The platform of the mechanized receiving catwalk is empty and is in the loading position on the floor of the rig (ready to be moved to the floor of the rig).

The pipe feed lever is located outside the impact area.

[251] The sequence of laying single-tubes from the center of the well to the receiving catwalks includes the following steps.

[252] Step 1: open the wedges and raise the drill string. The wedges on the spider open. The top drive/winch takes the weight of the drill string and also lifts the drill string out of the wellbore. They stop lifting when the single tube is above the height of the protrusion. The wedges on the spider close. The top drive/winch set the mass back on the wedges. See fig. 60A and 60B.

[253] Step 2: moving the platform of the mechanized receiving walkways and the pipe pusher to the laying position. The platform of the mechanized receiving walkway 600 is raised so that it is located exactly on the floor of the rig. The pipe pusher is moved to the position of laying on the floor of the drilling rig relative to the site. See fig. 61A and 61B.

[254] Step 3: moving the tong and lower stabilizing arm to the center of the well. The selected wrench is moved to the center 30 of the hole and raised to the height of the protrusion. The lower stabilizing arm 800 is moved to the center 30 of the hole above the working height of the drill tong. On the lower stabilizing arm 800, its guide cone is closed around the pipe. See fig. 62.

[255] Step 4: Breaking out the plug with a drill tong. The connection is unscrewed with a drilling key and the threads of the connection are unscrewed. The drilling key is opened and pushed into the ready position. (Alternatively, the wrench may remain in the center of the hole until the stand is raised by the top drive.) See fig. 63.

[256] Step 5 (optional, applied in case of lifting with liquid): pipe filled with liquid. If lifting with liquid is carried out, the spill device is moved to the center of the well and closed on the drill string. The top drive lifts the unscrewed pipe to ensure that the liquid from it drains into the anti-spill device. See fig. 55. The anti-spill device is then opened and retracted, while the lower stabilizing arm 800 guides the pipe over the anti-spill device. See fig. 64A and 64B.

[257] Step 6: moving the pipe with the top drive and bottom stabilizing arm from the center of the well to the mechanized catwalks. The top drive lifts the pipe from the protruding part and above the mechanized receiving walkways. The lower stabilizing lever guides the nipple end over the mechanized receiving bridges and places the nipple on the pipe pusher of the mechanized receiving bridges, which is in the position of laying on the drilling rig floor. See fig. 65A and 65B.

[258] Step 7: pipe laying on mechanized catwalks. The top drive links are shifted to place the elevator close to the mechanized receiving walkways. As the top drive is lowered in the direction of the floor, the pipe pusher of the mechanized receiving bridges is simultaneously moved down the platform for laying the pipe on the platform. The elevator is opened to release the pipe and the links are turned back (free inclination of the links). See fig. 66A and 66B.

[259] (X) SEQUENCE OF MOVING THE CASING FROM THE PICKUP WITH THE CASING WRENCH

[260] The initial equipment configuration for the casing to move sequence from the catwalks using the casing tong is as follows:

The top drive 200 is in the down position on the well center axis 30 and the elevator is closed around the protruding part of the pipe.

The casing string is suspended in a spider in the rig floor 6 such that approximately 1.2 m/4 ft of the drill string protrudes from the rig floor 6 .

The casing pipe is laid on the side for the casing pipe of mechanized receiving bridges (working side). Casing pipes cleaned and lubricated, without safety rings. Casing length measured for clarification.

The platform of the mechanized receiving walkways is empty and is in the loading position.

[261] The sequence of moving the casing from the catwalks using the casing tong includes the following steps.

[262] Step 1: Loading the casing onto the platform of the mechanized receiving catwalks. Casing loading pins are used to load one casing into the catwalk platform 600. See FIG. 69.

[263] Step 2: Move the walkway to the rig floor. Platform of the mechanized receiving walkways 600. See fig. 70A-70C.

[264] Step 3: Opening the elevator and raising to the hoist position. The top drive elevator 200 is opened and the links are tilted back so that the elevator can move away from the casing joint. See fig. 71A. The top drive is lifted to the lifting position 60 on the receiving walkways. See fig. 71b.

[265] Step 4: pushing out the casing. The pipe pusher of the mechanized receiving catwalks 600 pushes the casing pipe up from the platform to the putting on position. The top drive links are tilted forward to move the elevator towards the casing, and the elevator is slid onto the casing. See fig. 72A and 72B.

[266] Step 5: tightening the casing. The casing is pulled up by raising the top drive 200 such that the box end of the casing is raised by the elevator. As the top drive rises, the lower box end of the casing moves upward from the platform of the powered catwalks 600. Before the lower box end of the casing pipe exits the end of the platform of the powered catwalks 600, the lower stabilizing arm 800 is extended and its cone is closed to guide the casing. As the casing approaches vertical, the lower stabilizer arm centralizers 800 close on the casing. See fig. 73.

[267] Step 6: guiding the casing to the center of the well. The tong lever and casing tong are moved to the protrusion while the top drive 200 continues to raise the casing. When the pin end is raised above the protrusion, the lower stabilizing arm 800 guides the casing into the center 30 of the well. The catwalk platform is moved sideways and down into position to load the next casing. See fig. 74A. In an alternative embodiment that uses a wrench cart, a drill tong on the wrench cart can be used for the connection. See fig. 74b.

[268] Step 7: casing and make-up. The casing wrench guide is closed over the protruding portion. The top drive is lowered to insert the casing into the insertion guide. When the casing is in the insertion guide, the lower stabilizing arm 800 is released and retracted. The top drive is additionally lowered to insert the casing into the protruding part. The casing pipe is screwed with a casing wrench for threaded connection of the nipple end of the casing pipe with the coupling end of the protruding part. A casing wrench is then applied to tighten the lock. See fig. 75.

[269] Step 9: running the casing string. The casing wrench is moved to its ready position. Lift the mass of the casing string with a top drive/winch. Open the wedges in the spider. The casing string is lowered into the wellbore up to the protrusion height. Install the wedges in the spider. See fig. 76.

[270] (XI) SEQUENCE OF BREAKING OUT ONE CASING PIPE USING A CASING TOOL AND LAYING IT ONTO THE CATCH

[271] The sequence of breaking out one casing with a casing tong and placing a single casing string on the catwalk is very similar to the sequence of moving the casing off the catwalks with the casing tong. The difference is that the steps are performed in reverse order.

[272] (XII) SEQUENCE OF MOVING THE CASING PIPE FROM THE CATCHWAY USING THE TOP DRIVE AND THE CASING TOOL

[273] The initial equipment configuration for the sequence of moving the casing from the catwalks using the top drive and the casing running tool is as follows:

The top drive 200 is in the down position on the centerline 30 and the casing running tool is closed around the protruding portion of the pipe.

The casing string is suspended in a spider in the rig floor 6 such that approximately 1.2 m/4 ft of the drill string protrudes from the rig floor 6 .

The casing pipe is laid on the side for the casing pipe of mechanized receiving bridges (working side). Casing pipes cleaned and lubricated, without safety rings. Casing length measured for clarification.

The platform of mechanized receiving catwalks is loaded with a single-tube casing designed to move upwards.

The pipe feed arm is located on the top of the tower and the lower stabilizer arm is ready for use.

[274] The sequence of moving the casing from the catwalks using the top drive and the casing running tool includes the following steps.

[275] Step 1: Detach the casing running tool from the projection and raise the top drive to the lifting position. The casing running tool is disconnected from the protruding part. See fig. 77A. The top drive is raised to the lifting position on the receiving catwalks (above the casing). The pipe pusher of the mechanized catwalks is actuated to push the casing forward into the lifting position. See fig. 77B-77C.

[276] Step 2: putting on the elevator. The pulling elevator is placed above the casing. Install the safety pin (if it is a drag elevator with a manual winch). See fig. 78A-78C.

[277] Step 3: raising the casing to the center of the well with a top drive and a bottom stabilizing arm. The trolley for lowering and raising the key and the holding key are moved to the center of the well and raised to the height of the protrusion. The top drive links are (loosely) retracted to the center of the well 30 so that the casing is pinned over the protrusion and guided by the bottom stabilizing arm 800. The powered catwalk is moved to the casing loading position. See fig. 79A and 79B.

[278] Step 4: casing and make-up. The guide for holding the holding key is closed over the protruding part. The top drive is lowered to insert the casing into the insertion guide (the dragging elevator moves along the casing). When the casing is in the insertion guide, the lower stabilizing arm 800 is released and retracted. The top drive is additionally lowered to insert a casing running tool. See fig. 80A-80B.

[279] Step 5: loading the next casing onto the platform of the mechanized receiving catwalks. The casing pipes are placed on the casing side (working side) of the mechanized receiving catwalks. The loading fingers of the mechanized receiving bridges load one casing pipe onto the platform. See fig. 81.

[280] Step 6: Move the platform of the mechanized receiving bridge to the floor of the rig. Mechanized receiving walkways are moved to a position on the floor of the drilling rig. See fig. 82A and 82B.

[281] Step 7: engaging the casing running tool and making up the casing connection. With the casing running tool running, tie in and make up the connection according to the procedure for using the casing running tool. See fig. 83A and 83B.

[282] Step 8: Opening the holding key and moving the wrench trolley away. The holding key is opened. The wrench trolley is moved to its home or standby position. See fig. 84.

[283] Step 9: running the casing string and opening the elevator. Lift the mass of the casing string with a top drive/winch. Open the wedges in the spider. The casing string is lowered to the height of the protrusion and at the same time the casing string is filled with drilling mud. Stop running the casing string when the elevator is close to the rig floor. Open the elevator with a manual winch. See fig. 85.

[284] Step 10: Tilt the links outward and install the wedges. The links are tilted outward in the direction of the mechanized receiving walkways and the wedges are installed in the spider. See fig. 86.

[285] (XIII) SEQUENCE OF MOVING THE CASING FROM THE CATCHING STATION USING THE PIPE FEEDING LEVER AND THE CASING DRIVING TOOL

[286] The initial configuration of the equipment for the sequence of moving the casing from the catwalks using the pipe feed lever and the casing running tool is as follows:

The top drive 200 is in the down position on the centerline 30 and the casing running tool is closed around the protruding portion of the pipe.

The casing string is suspended in a spider in the rig floor 6 such that approximately 1.2 m/4 ft of the drill string protrudes from the rig floor 6 .

The casing pipe is laid on the side for the casing pipe of mechanized receiving bridges (working side). Casing pipes cleaned and lubricated, without safety rings. Casing length measured for clarification.

The platform of the mechanized receiving walkways is empty and is in the loading position.

The tubing feed arm and lower stabilizer arm hold the casing in the ready position on the rig floor. See fig. 87.

[287] The sequence of moving the casing from the catwalks using the pipe feed lever and the casing running tool includes the following steps.

[288] Step 1: Detach the casing running tool from the projection and raise the top drive to the lifting position. The casing running tool is disconnected from the protruding part. Raise the top drive to move away from the protruding part. The top drive is pushed in and the links are tilted relative to the vertical position. Raise the top drive and the casing running tool (CRT) to position the CRT above the casing. See fig. 88.

[289] Step 2: moving the casing to the center of the well. The pipe feed arm 500 and the lower stabilizer arm 800 move the casing section to the center 30 of the well and raise it to the height of the protrusion. The tubing arm 500 is extended toward the center 30 of the well so that the pin end is over the projection and guided by the lower stabilizing arm 800. See FIG. 89A and 89B.

[290] Step 3: Inserting the casing. The casing wrench and the insertion guide are interlocked at the protruding part. The pipe wrench is placed and closed on the casing (may be closed before or after the casing is inserted). The tubing lever 500 is lowered to insert the casing. See fig. 90. The lower stabilizing arm is released and retracted when the casing is inside the insertion guide. The tubing lever 500 continues to run the casing (approximately 1 m/3 ft) to provide make-up space with the casing running tool.

[291] Step 4: loading the casing onto the site. The casings are placed on the casing side (working side) of the catwalk platform 600. The loading fingers load one casing on the catwalk platform 600. See FIG. 91.

[292] Step 5: Moving the casing to the rig floor. The platform of the receiving catwalks is extended to the position of the drilling rig floor, and the casing pipe is moved upwards from the platform for supplying the casing pipe to the drilling floor by the pusher of the tool. See fig. 92A and 92B.

[293] Step 6: make-up of the casing connection. The lever for lowering and raising the key and the key for casing pipes make up the connection by twisting the threads and applying a tightening torque. The key for casing pipes is opened and the lever for lowering and raising the key is moved back; optionally, it can be moved to the standby or home position. See fig. 93A. Alternatively, the casing connection can be screwed together with a tong wrench and a casing tong. See fig. 93b. Yet another alternative is to make up the casing connection with a casing running tool by twisting and applying top drive torque.

[294] Step 7: inserting a casing running tool. The casing running tool is driven and fixed in the casing. The pipe feed lever 500 is opened and moved to the lift position on the catwalk. See fig. 94A and 94B.

[295] Step 8: running the casing string. The top drive/winch lifts the mass of the casing string. The wedges in the spider open. The top drive/winch lowers the casing string into the wellbore to the protruding height. Optionally, the casing may be filled with drilling fluid. See fig. 95A and 95B.

[296] Step 9: pushing out the casing. The tool feed lever 500 is moved to the powered catwalk position so that a section of casing can be placed in its elevator. The pipe pusher pushes the casing string section up from the platform. The tool feed lever 500 puts the elevator on the casing section. See fig. 96.

[297] Step 10: tightening the casing. When its elevator is closed around the casing, the casing is lifted by the pipe feed lever 500 and the casing is pushed up off the platform by the pusher of the tool. Before the casing leaves the catwalk area, the lower stabilizing arm 800 is extended to the casing and prepared for guidance, and the cone is closed on the casing. As the casing approaches vertical, the lower stabilizer arm centralizer 800 is locked onto the casing. The platform of the receiving catwalk is returned to load the next casing. See fig. 97A-97B.

[298] Step 11: guiding the casing. The tubing feed arm 500 continues to be raised and pushed in to bring the casing to a vertical position before it is rotated in the direction of the top drive. The lower stabilizing arm 800 guides the casing into a vertical position. See fig. 98A-98B.

[299] Step 12: installation of wedges. Wedges are installed to hang the casing string. See fig. 99A-99B.

[300] (XIV) MAKE-UP SEQUENCE OF THE DRILL STRING STAND OUT OF THE CENTER OF THE WELL

[301] The initial equipment configuration for the off-center drill string make-up sequence is as follows:

All devices are empty.

The upper part of the intermediate latch 430 of the spark plug is retracted.

The pipe is loaded onto the catwalk conveyor, cleaned and lubricated, without safety rings.

Optionally, lubrication may be performed as part of the plug make-up sequence.

[302] The sequence of making up the candles not in the center of the well includes the following steps.

[303] Step 1: placing the pipes on the conveyor. Then, one pipe is loaded onto the platform of mechanized receiving walkways 600 by a conveyor. See FIG. 100.

[304] Step 2: move the pad to the rig floor. See fig. 101A and 101B. The pipe feed arm 500 is lowered so that its elevator is below the height of the pipe. The pipe feed lever 500 is tilted in the direction of the receiving catwalks 600.

[305] Step 3: ejection of the pipe. The pipe pusher of the mechanized receiving bridges 600 pushes the pipe up from the platform to the putting on position. See fig. 102A and 102B.

[306] Step 4: pulling up the first pipe from the mechanized receiving catwalks. The pipe feed lever 500 is raised slightly to slide the elevator onto the pipe at the platform of the catwalk 600. The elevator latch is closed. The pipe is pulled up by raising the pipe feed lever 500 up the derrick and the pipe pusher follows it. Before the pipe leaves the site, the lower stabilizing arm 800 is extended to prepare for guiding the pipe. The cone is then closed on the pipe as it rises. When the pipe approaches the vertical position, the centralizer of the lower stabilizing arm 800 is closed on the pipe. The platform of the receiving catwalks 600 is returned to load the second pipe. See fig. 103A and 103B.

[307] Step 5: placing the first pipe in the pipe extension hole. The first pipe is lowered into the extension hole 40 by means of the pipe feed lever 500 to the proper protrusion height (1 m/3 ft). The upper part of the intermediate latch 430 candles put forward and close on the first pipe. The lower stabilizing arm 800 is detached from the first pipe and retracted. The lower latch 440 candles put forward and close on the first pipe. The pipe feed lever 500 is lowered to transfer the mass of the first pipe to the latches, the elevator is opened, and the pipe feed lever 500 is moved away from the projection. See fig. 104A and 104B.

[308] Step 6: pulling up the second pipe. The elevator of the pipe feed arm 500 is again placed below the height of the pipe so that the elevator is open and tilted towards the catwalks 600. After loading the second pipe and extending the platform, the second pipe is moved up from the platform by the tool pusher. The pipe feed arm 500 is raised slightly until the elevator engages with the second pipe and the elevator latch is locked on it. The second pipe is pulled up by raising the pipe feed lever and pushed out by the tool pusher. Before the second pipe leaves the catwalk area, the lower stabilizing arm 800 is extended towards the pipe and prepared for guidance, and the cone is closed on the pipe. As the pipe approaches a vertical position above the extension hole 40, the lower stabilizer arm centralizer 800 is closed on the second pipe. If lubrication is desired, the second pipe is moved to the spark plug position 50 before being moved to the extension hole 40. The platform of the receiving bridges is returned to load the third requirement. See fig. 105A-105C.

[309] Step 7: insertion and make-up of the second pipe. The second pipe is moved over the protruding part of the first pipe in the pit 40 to build pipes. The drill tong 760 on the tong handle is moved to the protruding portion. The guide for inserting the drilling key is closed on the protruding part of the first pipe. The pipe feed lever is lowered to insert the second pipe into the protruding portion of the first pipe. The connection is twisted and screwed with a drilling key. The lower stabilizing arm is opened and retracted. The drill key is pushed into the ready position. See fig. 94A and 94B.

[310] Step 8: running the twin pipe into the extension hole. The pipe feed lever is raised to lift the mass of the two-tube. The intermediate latch of the candle is opened to release the two-tube. The lower latch of the candle is pushed into position in the pit for pipe extension and its guide is closed around the two-pipe for the setting mode. The twin tube is lowered by means of the pipe feed lever into the extension hole to the proper protrusion height while the lower spark plug guides the twin tube into the extension hole and is opened slightly to allow the pipe lock to pass. The intermediate spark plug guide is then closed and finally the twin tube is clamped to position the twin tube at the height of the protrusion. The pipe feed lever is lowered to transfer the mass of the two-tube to the intermediate spark plug retainer. The pipe feed lever elevator is opened and moved away from the protruding part. Steps 6 and 7 are repeated to lift the third single tube. See fig. 107.

[311] Step 9: moving the spark plug to the spark transfer position. The lower latch 440 of the candle is pushed to the pipe in position in the pit for pipe extension and its guide is closed. The pipe feed arm 500 is raised to lift the candle mass. The guide and the grip of the intermediate latch 430 candles open. The upper part of the intermediate latch 430 candles slide. The pipe lever 500 lifts the stinger (R2 or R3) out of the extension pit 40 and stops when the stinger is raised such that the pin end is above the height of the lubrication station at the spark plug transfer position 50. The pipe feed lever 500 and the lower stabilizing arm 800 move the spark plug to the position where it is suspended in the spark plug transfer position 50 . The candle is then inserted into the oiler, if selected, where the nipple is washed and lubricated. The upper retainer of the candle is pulled out to close its guide on the candle. The pipe feed lever 500 is opened and moved away from the candle. See fig. 108A and 108B.

[312] Step 10: Installing the candle on the candlestick. The bridge stacker 350 and candlestick guide arm 950 are moved to the candle transfer position 50 and their guides and grips are closed on the candle. The upper and lower latches 420 and 440 of the spark plug are released and retracted. The bridge stacker 350 and candlestick guide arm 950 are moved to fit onto the candlestick at a selected position in the top magazine 310. See FIG. 109A-109D.

[313] (XV) STANDING SEQUENCE OF DRILL STRING STANDS (NOT IN THE CENTER OF THE WELL)

[314] The initial equipment configuration for the stacking sequence of the drill string (not in the center of the well) is as follows:

All devices are empty.

The upper part of the intermediate latch 430 of the spark plug is retracted.

The powered walkway conveyor is empty and ready to receive the drill pipe.

[315] The sequence of stacking candles of the drill string (not in the center of the well) includes the following steps.

[316] Step 1: lifting the candle from the candlestick. The bridge stacker 350 and candlestick guide arm 950 are moved toward the candlestick to lift the candle from a selected position in the candlestick/top magazine 310. See FIG. 110A and 110B.

[317] Step 2: moving the spark plug to the spark transfer position. The bridge stacker 350 and the spark plug guide arm 950 move the spark plug to the spark transfer position 50. On the upper and lower retainers 420 and 440, the candles close their clips to hold the candle. Using an oiler, rinse and lubricate the nipple (if selected). The bridge stacker 350 and candlestick guide arm 950 are moved back toward the candlestick to lift another candle from another selected position in the candlestick/top magazine 310. See FIG. 111A and 111B.

[318] Step 3: moving the plug from the transfer position of the plug to the extension hole. The pipe feed lever 500 and the lower spark plug latch 440 are moved to the spark plug at the spark plug transfer position 50 and their clamps are closed on the spark plug. The upper latch 420 of the candle is opened and pushed back. The pipe feed lever 500 raises the spark plug at the spark transfer position 50 . The pipe feed lever 500 and lower spark plug retainer 440 move and guide the spark plug from the spark plug transfer position 50 to position 40 in the pipe extension hole. See fig. 112.

[319] Step 4: Run the stand into the extension hole. The pipe feed arm 500 is lowered to insert a spark plug into the pipe extension hole 40 . The upper part of the intermediate latch 430 candles put forward. The candle is lowered until it protrudes approximately 1 m/3 ft. The guide and clamp of the intermediate latch 430 of the candle are closed on the candle and receive its mass. The lower latch 440 of the candle is opened and pushed back. See fig. 113.

[320] Step 5: breakout of the upper single tube. The wrench 760 is extended to the hole 40 to build up pipes to engage with the candle. The lower stabilizing lever 800 is extended to the pit 40 for pipe extension and its cone is closed on the upper single tube of the candle. Drill wrench 760 unscrew the connection and untwist the threads. See fig. 115A and 115B.

[321] Step 6: Laying the top single tube onto the powered walkways. The platform of mechanized receiving walkways 600 is moved to the floor of the drilling rig for pipe laying. The pipe feed lever 500 lifts the unscrewed upper single tube from the protruding part and with the help of the lower stabilizing lever 800 it is directed to a position above the platform of the receiving catwalks 600. The lower stabilizing lever 800 moves the nipple end above the platform and the elevator of the pipe feed lever 500 is tilted towards the platform. The pipe arm 500 is moved down the mast 10 to lower the top single tube as the pipe pusher pulls the pin end down from the platform of the catwalk 600. With the top single tube loaded onto the deck, the pipe feed arm 500 elevator is opened and tilted back towards the mast 10. See FIG. fig. 115A and 115B.

[322] Step 7: unloading the top single tube onto the catwalk conveyor. The pipe pusher pulls the upper single tube down from the platform of the receiving bridges to the unloading position. The platform of the receiving catwalk 600 is tilted away from the floor 6 of the rig to lower it next to the conveyor. The upper one-tube is unloaded from the platform onto the conveyor. The platform of the receiving bridges 600 is again put forward to the floor 6 of the drilling rig to obtain the next single tube. See fig. 116A and 116B.

[323] Step 8: Lifting the two-pipe in the pit for pipe extension. The pipe feed arm 500 is rotated and lowered to snap onto the projecting portion in the pipe extension pit 40 . The pipe feed lever elevator 500 is closed on the protruding part of the two-tube. The pipe feed lever 500 is raised to receive the mass of the two-tube. On the intermediate latch 430, the candles open its clamp when the mass of the two-tube is unloaded from it. The two-pipe is raised to the height of the protrusion in the pit 40 for building pipes. The clamp of the intermediate latch 430 of the candle is closed on the two-tube and receives mass on it when the tube feed lever 500 is slightly lowered. See fig. 117.

[324] Step 9: breakout of the middle single tube. The wrench 760 is extended to the hole 40 for pipe extension. The lower stabilizing arm 800 is extended and its cone is closed on the middle single tube. Drill wrench 760 unscrew the connection and untwist the threads. The wrench is returned to its ready position. See fig. 114A and 114B.

[325] Step 10: Laying the middle single tube. The platform of mechanized receiving walkways 600 is moved to the floor of the drilling rig for pipe laying. The pipe feed lever 500 lifts the unscrewed middle single tube from the protruding part and with the help of the lower stabilizing lever 800 it is directed to a position above the platform of the receiving walkways 600. The lower stabilizing lever 800 moves the nipple end above the platform and the elevator of the pipe feed lever 500 is tilted towards the platform. The pipe arm 500 is moved down the mast 10 to lower the middle single tube as the pipe pusher pulls the nipple end down from the platform of the catwalk 600. When the single tube is loaded onto the deck, the elevator of the pipe arm 500 is opened and tilted back towards the mast 10. See FIG. . 115A and 115B.

[326] Step 11: unloading the middle single tube onto the receiving bridge conveyor. The pipe pusher pulls the middle one-tube down from the platform of the receiving bridges 600 to the unloading position. The platform of the receiving catwalk 600 is tilted away from the floor 6 of the rig to lower it next to the conveyor. The middle one-tube is unloaded from the platform onto the conveyor. The platform of the receiving bridges 600 is again put forward to the floor 6 of the drilling rig to obtain the next single tube. See fig. 116A and 116B.

[327] Step 12: Lifting the bottom single tube in the extension hole. The pipe feed arm 500 is rotated and lowered to snap onto the protruding portion of the lower single pipe in the extension pit 40 . The pipe feed arm elevator 500 is closed at the protruding portion. The pipe feed arm 500 is raised to receive the mass of the lower single pipe. On the intermediate latch 430, the candles open its clamp when the mass of the lower single tube is unloaded from it. The lower stabilizing arm 800 is extended and its cone is closed around the lower single tube.

[328] Step 13: Laying the lower single tube. The pipe feed lever 500 raises the lower single tube from the pit 40 for pipe extension and with the help of the lower stabilizing lever 800 it is directed to a position above the platform of the receiving walkways 600. The lower stabilizing lever 800 moves the nipple end above the platform and the elevator of the pipe feed lever 500 is tilted towards the platform. The pipe arm 500 is moved down the mast 10 to lower the lower single tube as the pipe pusher pulls the nipple end down from the platform of the catwalk 600. When the single tube is loaded onto the platform, the elevator of the pipe arm 500 is opened and tilted back towards the mast 10. See FIG. . 115A and 115B.

[329] Step 41: unloading the lower single tube onto the receiving bridge conveyor. The pipe pusher pulls the lower single tube down from the platform of the receiving bridges 600 to the unloading position. The platform of the receiving catwalk 600 is tilted away from the floor 6 of the rig to lower it next to the conveyor. The lower one-tube is unloaded from the platform onto the conveyor. See fig. 116A and 116B.

[330] (XVI) CASING STANDER MAKE-UP SEQUENCE NOT IN THE CENTER OF THE WELL

[331] The initial equipment configuration for the off-centre casing string make-up sequence is as follows:

Drilling can continue.

All devices are empty.

The upper part of the intermediate latch 430 of the spark plug is retracted.

Casing pipe loaded on casing conveyor, cleaned and lubricated, no safety rings.

Optionally, lubrication may be performed as part of the plug make-up sequence.

[332] The sequence of make-up of a stand-in casing string not in the center of the well includes the following steps.

[333] Step 1: placing the casing on the conveyor. Then, one casing pipe is loaded by a conveyor onto the platform of mechanized receiving catwalks 600. See FIG. 118A and 118B.

[334] Step 2: move the pad to the rig floor. See fig. 119A and 119B. The pipe feed arm 500 is lowered so that its elevator is below the height of the pipe. The pipe feed lever 500 is tilted in the direction of the receiving catwalks 600.

[335] Step 3: pushing out the casing. The pipe pusher of the mechanized receiving catwalks 600 pushes the casing pipe up from the platform to the putting on position. See fig. 120A and 120B.

[336] Step 4: Retracting the first casing from the powered catwalks. The tubing lever 500 is raised slightly to slide the elevator onto the casing at the walkway platform 600. The elevator latch is closed. The casing is pulled up by lifting the casing feed arm 500 up the derrick 10 and the pusher follows. Before the casing pipe leaves the site, the lower stabilizing arm 800 is extended to prepare for guiding the pipe. The cone is then closed on the casing as it is raised. As the casing approaches a vertical position, the lower stabilizer arm centralizer 800 is locked onto the casing. The platform of the receiving catwalk 600 is returned to load the second casing. See fig. 121A-121C.

[337] Step 5: Placement of the lower casing in the extension hole. The lower casing is run into the extension hole 40 by means of the pipe feed arm 500 to the proper protrusion height (1 m/3 ft). The upper part of the intermediate latch 430 candles put forward and close on the first pipe. The lower stabilizing arm 800 is detached from the first casing and retracted. The lower latch 440 of the plug is extended and closed to guide the first pipe. The pipe feed lever 500 is lowered to transfer the mass of the first pipe to the latches, the elevator is opened, and the pipe feed lever 500 is moved away from the projection. See fig. 122.

[338] Step 6: Pull up the upper casing. The pipe arm 500 elevator is again placed below the pipe height so that the elevator is open and tilted towards the catwalks 600. After the top casing is loaded and the platform is extended, the push tool moves the top casing up off the platform. The pipe feed lever 500 is raised slightly until the elevator engages the pipe and the elevator latch is locked on it. The upper casing is tightened by raising the pipe feed lever and pushed out by the tool pusher. Before the upper casing pipe leaves the catwalk site, the lower stabilizing arm 800 is extended to the pipe and prepared for guidance, and the cone is closed on the pipe. As the upper casing approaches a vertical position above the extension hole 40, the lower stabilizer arm centralizer 800 is closed on the second pipe. If lubrication is desired, the upper casing is moved to the spark plug transfer position 50 before being moved to the extension hole 40 . The platform of the receiving bridges is returned to load the third requirement. See fig. 123A and 123B.

[339] Step 7: insertion and make-up of the upper casing. The top casing is moved over the protruding portion of the bottom casing in the hole 40 to build up the pipes. The drill tong 760 on the tong handle is moved to the protruding portion. The guide for inserting the drilling key is closed on the protruding part of the lower casing pipe. The tubing lever is lowered to insert the upper casing into the protruding portion of the lower casing. The connection is twisted and screwed with a drilling key. The lower stabilizing arm is opened and retracted. The drill key is pushed into the ready position. See fig. 124A and 124B.

[340] Step 8: Run the twin pipe into the pipe extension hole (not applicable for Range 3). The pipe feed arm 500 is raised to lift the mass of the two-tube. The intermediate latch 430 of the spark plug is opened to release the two tubes. The lower latch 440 of the candle is pulled out to position 40 in the pit for pipe extension and its guide is closed around the two-tube for the setting mode. The twin tube is lowered by the pipe feed lever 500 into the extension hole 40 to the proper protrusion height while the lower fixture 440 guides the twin tube into the extension hole 40 and opens it slightly to allow the pipe lock to pass. The guide of the intermediate latch 430 of the spark plug is then closed and finally the twin tube is clamped to position the twin tube at the height of the protrusion. The tube feed lever 500 is lowered to transfer the weight of the twin tube to the intermediate spark plug retainer 430. The elevator of the pipe feed lever 500 is opened and moved away from the projecting part. Steps 6 and 7 are repeated to lift the third single tube if Range 2 is used. See FIG. 125A and 125B.

[341] Step 9: moving the casing stand to the stand transmission position. The lower latch 440 of the candle is pushed to the pipe in position in the pit for pipe extension and its guide is closed. The tubing lever 500 is raised to lift the mass of the casing stand. The guide and the grip of the intermediate latch 430 candles open. The upper part of the intermediate latch 430 candles slide. The tubing lever 500 raises the casing stalk (R2 or R3) out of the extension hole 40 and stops when the stalk is raised such that the pin end is above the height of the lubrication station at the plug transfer position 50. The pipe feed lever 500 and the lower stabilizing arm 800 move the spark plug to the position where it is suspended in the spark plug transfer position 50 . The candle is then inserted into the oiler, if selected, where the nipple is washed and lubricated. The upper retainer of the candle is pulled out to close its guide on the candle. The pipe feed lever 500 is opened and moved away from the candle. See fig. 126A and 126B.

[342] Step 10: Installing the casing stand on the stand. The bridge stacker 350 and the standoff guide arm 950 are moved to the standoff transfer position 50 and their guides and grips are engaged on the standpipe stand. The upper and lower latches 420 and 440 of the spark plug are released and retracted. The bridge stacker 350 and the standoff guide arm 950 are moved to place the casing stands on the standoff at the selected position in the top magazine 310. See FIG. 127A-127D.

[343] (XVII) SEQUENCE OF LAYING STANDING CASING OUT OF THE CENTER OF THE WELL

[344] The sequence for laying off-center casing strings is similar to the make-up sequence for off-center casing strings, except that the steps are performed in reverse order.

[345] (XVIII) DRILL PIP CONNECTION SEQUENCE

[346] The initial equipment configuration for the drill pipe connection sequence is as follows:

Standpipe drilling is carried out all the way down the wellbore, and well reaming, inclinometry, etc. are performed according to the drilling program.

One drill pipe stand is raised by the pipe feed arm/lower stabilizing arm to the stand transfer position to the level of the projection above the extension hole, with the pipe feed arm elevator facing the top drive. The rig floor is in a state of readiness.

The bridge stacker and candlestick guide arm are empty and on their way to lift a new candle in the top magazine/candlestick.

[347] The drill pipe connection sequence includes the following steps.

[348] Step 1: Stop drilling and break out the top drive connection. Drilling work is stopped. When the protruding part of the drill string is at a height (approximately 1.5 m/5 ft), slips are installed in the spider. The mass of the drill string is mounted on wedges. The top drive connection is unscrewed and the threads are untwisted. See fig. 128. The top drive 200 is then lifted up the tower 10.

[349] Step 2: Raise the top drive to the connection height. When the top drive 200 is retracted by its cart, the top drive 200 is raised to a height sufficient to connect to the next stand in the drill string. The elevator links are tilted relative to the vertical under the top drive. See fig. 129A and 129B.

[350] Step 3: moving the candle from the position in the extension hole to the center of the well. The pipe feed arm 500 and the lower stabilizing arm 800 move the candle to the center 30 of the well from a standby position on the floor of the drilling rig above the hole 40 for pipe extension. The selected drilling tong (cart for lowering and raising the key) is moved to the center of the well. See fig. 130A and 130B.

[351] Step 4: inserting the candle into the projection in the center of the well. The top drive 200 remains at the proper height and is moved away from the center 30 of the well. The holding wrench 760 and its hook-up guide are closed at the projecting portion to facilitate the hook-up. The tubing arm 500 lowers the plug to insert the plug into the projection, and continues to lower (approximately 2 m/6 ft) after insertion to provide space for the top drive to make up. The lower stabilizing arm 800 is released and moved away from the center 30 of the well. One option is to start the sequence for tightening and make-up of the lower connection with a drilling tong. See fig. 131A and 131B.

[352] Step 5: connection of the top drive. When the top drive 200 is at the proper height, the cart is extended to place the top drive 200 in the center 30 of the well. The slings are tilted towards the tower 10 and positioned for the drilling position. The top drive is lowered to insert into the plug and the top drive is then rotated to tighten the top and bottom connections against the action of the holding tool. At the pipe feed lever 500, its elevator is opened, the lever is moved away from the center 30 of the well, and rotated to lift the next plug to the plug transfer position. The drilling key is opened and pushed into its ready position. See fig. 132A and 132B. Optionally, the wrench is released and moved to the ready position after the bottom connection is made up.

[353] Step 6: open slips and resume drilling. The top drive/winch lifts the mass of the drill string. The wedges in the spider open. Drilling continues. See fig. 133.

[354] Step 7: Raising the next candle from the candlestick. The bridge stacker 350 and candlestick guide arm 950 lift the other candle from its chosen position in the candlestick/top magazine 310. See FIG. 134A and 134B.

[355] Step 8: moving the candle to the transmission position of the candle. On the top drive 200, its elevator is opened, moved away from the protruding part and raised to the top stop. The bridge stacker 350 and the spark plug guide arm 950 move the spark plug to the spark transfer position 50. The upper and lower spark plug retainers 420 and 440 interlock to hold the spark plug in position. With an oiler installed in position 50 of the spark plug, wash and lubricate the nipple, if selected. The bridge stacker 350 and candlestick guide arm 950 lift the other candle from its chosen position in the candlestick/top magazine 310. See FIG. 135A and 135B.

[356] (XIX) WELL BACK PROCESSING SEQUENCE

[357] The initial equipment configuration for the reverse drilling sequence is as follows:

The top drive is in the bottom position, retracted by the cart, and the links are in the vertical position, so that the elevator is under the top drive. See fig. 136.

The slips are closed on the drill string at standard protrusion (approximately 1.5 m/5 ft).

The tubing arm 500 and the lower stabilizing arm 800 are open in the plug transfer position (the plug is fed from the center of the well to the plug transfer position).

The upper and lower spark plug retainers are closed on the spark plug in the spark plug transfer position. Intermediate spark plug lock open and retracted.

The bridge stacker and candlestick guide arm are empty and are on their way back from the top magazine/candlestick to receive the next candle in the candle transfer position.

[358] The well reverse engineering sequence includes the following steps.

[359] Step 1: top drive make-up. The top drive 200 is extended on the top drive cart to the center 30 of the well. The elevator links are tilted back to their original position. The top drive is lowered, twisted and screwed with the drill string. See fig. 137A and 137B.

[360] Stage 2: reworking the wellbore for a standoff length. The wedges are opened and the top drive/winch lifts the mass of the drill string. The internal blowout preventer is opened and contains a mud pump to circulate the drilling fluid. The top drive 200 rotates the drill string and raises it in the derrick 10 to ream the wellbore until the top drive reaches the connection height. Stop the rotation of the drill string by the top drive 200 and stop the application of torque to the drill string. The mud pumps are stopped and the internal blowout preventer is closed. The wedges in the spider close when the drill string is at the proper protrusion height. The tubing arm 500 and the lower stabilizing arm 800 are moved from the stand transfer position to the rig floor to a safe standby position. The pipe arm elevator 500 faces the top drive 200. See FIG. 138A and 138B.

[361] Step 3: moving the candle from the candle transfer position to the candlestick/top magazine. The bridge stacker 350 and candlestick guide arm 950 are moved towards the spark plug at the spark plug transfer position 50 and their grips and guides on the spark plug are closed. The upper and lower latches 420 and 440 of the spark plug are released and retracted. The bridge stacker 350 and candlestick guide arm 950 lift the candle and move it to a selected position in the candlestick/top magazine where it is released and held in position in the top magazine 310. See FIG. 139A and 139B.

[362] Step 4: preparing to unscrew the stand from the drill string. The pipe feed arm 500 and the lower stabilizer arm 800 are moved to the center 30 of the well and close their elevator and guide on the stand in the drill string. The tong 760 is moved to the center of the hole and raised to the height of the protrusion. See fig. 140A and 140B.

[363] Step 5: Unscrew the top drive from the spark plug. The top drive 200 is unscrewed and the threads of its connection with the spark plug are untwisted. The winch raises the top drive 200 to move away from the top of the candle. The top drive is moved away from the well center 30 on a trolley and the elevator links are rotated back to a vertical position, whereby the elevator is freely moved to a position under the top drive. The winch lowers the top drive 200 down the tower 10 in the direction of the floor 6 of the drilling rig. See fig. 141A and 141B.

[364] Step 6: unscrewing the candle from the drill string. The drill key 760 unscrews the candle from the protruding part and unwinds the threads of the lock. See fig. 142A and 142B.

[365] Step 7: Drain the drilling fluid from the candle. The wrench 760 is released and moved away from the projection to its ready position. The anti-spill device is extended to the center 30 of the well and closed at the broken joint. The piping lever 500 raises the candle above the projection to allow the liquid in the candle to drain from the candle into the anti-spill device. The anti-spill device is opened at a distance from the candle/protrusion and moved to its standby position. See fig. 143.

[366] Step 8: moving the candle from the center of the well. The pipe feed lever 500 and the lower stabilizing arm 800 move the plug from the center 30 of the well to the plug transfer position 50. Upon receipt, the tube feed lever 500 lowers the mass release plug at the plug transfer position 50. Upper and lower spark plug retainers 420 and 440 lock onto the spark plug to hold it in position. If it is selected, with an oiler installed in the transfer position of the candle, rinse and lubricate the nipple. The top drive 200 continues to be lowered to the floor 6 of the drilling rig. See fig. 144A and 144B.

[367] Step 9: Installing the candle on the candlestick. The candle is moved from the candle transfer position to the candlestick/top magazine. The bridge stacker 350 and candlestick guide arm 950 are moved towards the spark plug at the spark plug transfer position 50 and their grips and guides on the spark plug are closed. The upper and lower latches 420 and 440 of the spark plug are released and retracted. The bridge stacker 350 and candlestick guide arm 950 lift the candle and move it to the selected position in the candlestick/top magazine where it is released and held in position in the top magazine 310. The bridge stacker 350 and candlestick guide arm 950 are returned to the candle transfer position. See fig. 145A and 145B.
