Description
Technical Field
Embodiments of the present disclosure relate to a coiled tubing pipe stripper.
Background
With the development of coiled tubing technology, coiled tubing is increasingly widely used. The coiled tubing has good flexibility, can be wound on a roller for transportation, and has better transportation flexibility compared with the conventional tubing; the length of the continuous oil pipe can reach thousands of meters, and compared with a conventional oil pipe, the coiled oil pipe is more convenient to lower into an oil-gas well. The coiled tubing can replace the conventional tubing to carry out various operations, for example, the coiled tubing is applied to various operation scenes such as well repair, well drilling, well completion, well logging and the like of an oil-gas field, and has the characteristics of operation under pressure and continuous tripping.
Current coiled tubing needs to use the transportation cylinder to transport respectively and uses the work cylinder to transfer the oil pipe operation. When the oil pipe is lowered, high-pressure liquid needs to be injected into the well through the oil pipe while the oil pipe is lowered, and the transportation roller cannot achieve the operation. Therefore, a pipe stripper is required to transfer the coiled tubing from the transport drum to the work drum before the above-mentioned operations are performed. The above transfer operation increases the work preparation time and increases the work cost.

The embodiment of the present disclosure provides a coiled tubing pipe stripper, including: base, first support, second support and rotary joint. The first support and the second support are both positioned on the base; the rotary joint is positioned on one side of the first bracket, which is far away from the second bracket. The first support comprises a first driving device, the first driving device comprises a transmission shaft, a fluid channel extending along the axis direction of the transmission shaft is arranged in the transmission shaft, the transmission shaft is arranged on one side, close to the second support, of the rotary joint, and the first end, facing the rotary joint, of the transmission shaft is rotatably connected with the first end, facing the transmission shaft, of the rotary joint. The coiled tubing pipe rewinder can be provided with a roller, and double functions of transportation and operation of the coiled tubing are realized, so that the coiled tubing operation process is simplified, and the cost is saved.
The coiled tubing pipe stripper provided by the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic plan structure view of a coiled tubing pipe stripper provided in an embodiment of the present disclosure, and fig. 2 is a schematic three-dimensional structure view of the coiled tubing pipe stripper provided in an embodiment of the present disclosure. As shown in fig. 1 and 2, the coiled tubing pipe rewinder comprises: a base 10, a first bracket 21, a second bracket 22 and a rotary joint 30. In operation, the base 10 is placed on the ground or a working platform to carry the whole pipe bender. The first and second supports 21 and 22 are each located on the base 10 for supporting an object to be carried, such as a driving device or a roller, etc., disposed thereon. The rotary joint 30 is located on a side of the first bracket 21 away from the second bracket 22, and two ends of the rotary joint can respectively communicate with two relatively rotating components and have a sealing function. The first bracket 21 includes a first driving device 211, the first driving device 211 includes a transmission shaft 2111, and a fluid passage extending along the axial direction of the transmission shaft 2111 is provided therein. A drive shaft 2111 is provided on the side of the rotary joint 30 adjacent to the second bracket 22, and a first end 2111a of the drive shaft 2111 facing the rotary joint 30 is rotatably connected to a first end 30a of the rotary joint 30 facing the drive shaft 2111.
In the coiled tubing pipe stripper provided by the embodiment of the disclosure, the transmission shaft is internally provided with the fluid channel, so that the transmission shaft can not only transmit power, but also convey fluid. For example, a drive shaft may be used to convey high pressure fluids. For example, the fluid passages of the drive shaft may be rated to operate at 15000psi (pounds force per square inch). Of course, the above rated operating pressure is merely an example, and the embodiments of the present disclosure are not limited thereto.
The coiled tubing pipe-laying device provided by the embodiment of the disclosure can be also provided with a roller, and the coiled tubing wound on the roller is communicated with the fluid channel in the transmission shaft. Therefore, after the coiled tubing stripper provided by the embodiment of the disclosure is configured and transported to a working site, the coiled tubing stripper can be directly connected with a high-pressure manifold on the site without being inverted to another working roller, and high-pressure fluid can be injected into the tubing while the tubing is lowered for operation. Therefore, the coiled tubing pipe-pouring device provided by the embodiment of the disclosure can realize dual functions of coiled tubing transportation and operation, thereby simplifying the coiled tubing operation process and saving the cost.
Fig. 3 is a schematic diagram of another three-dimensional structure of the coiled tubing pipe stripper according to an embodiment of the present disclosure. As shown in fig. 3, the coiled tubing pig may further comprise a roller 40 and a first manifold 50. The roller 40 is rotatably connected with the first driving device 211 and the second bracket 22, respectively, and is configured to wind coiled tubing (coiled tubing is not shown in the figure), for example, the roller 40 may carry coiled tubing having an outer diameter of 1.25-4 inches, but the embodiment of the present disclosure is not limited thereto.
As shown in fig. 3, the drum 40 is positioned between the first bracket 21 and the second bracket 22, and the first manifold 50 is positioned within the drum 40. For example, the roller 40 may be rotated by the first driving device 211 to retract or release the coiled tubing. For example, the first manifold 50 is fixedly connected to the drum 40 and can rotate with the drum 40, and one end of the first manifold 50 is always connected to one end of the coiled tubing during the rotation of the drum 40.
Fig. 1 schematically shows the connection relationship of the first manifold 50 and the transmission shaft 2111. As shown in fig. 1, a first end 50a of the first manifold 50 is connected to a second end 2111b of the drive shaft 2111, and a second end 50b of the first manifold 50 is configured to connect to an end of coiled tubing.
For example, as shown in fig. 1 or 3, the coiled tubing stripper may further comprise a second manifold 60, one end of the second manifold 60 being connected to the second end 30b of the swivel 30. The other end of the second manifold 60 may be connected to external equipment to tap external high pressure fluid into the coiled tubing. In this manner, during work such as lowering the coiled tubing, high pressure fluid may be injected into the coiled tubing through the second manifold 60 via the swivel 30, the drive shaft 2111 and the first manifold 50. In the operation process, the first manifold 50, the transmission shaft 2111 and the roller 40 synchronously rotate, so that the connection part of the first manifold and the coiled tubing is always relatively fixed; a second manifold 60 is attached to the other side of the rotary joint and remains stationary during rotation of the drum. For example, the high pressure fluid may be a gas or a liquid, selected or adjusted according to the in situ process.
As shown in fig. 1, the first end 2111a and the second end 2111b of the transmission shaft 2111 protrude out of both sides of the first bracket 21, respectively. The first bracket 21 and the transmission shaft 2111 are supported by two support points, each of which is provided with a bearing. During a coiled tubing lowering operation, the drive shaft 2111, the drum 40 and the first manifold 50 rotate together and the second manifold 60 on the other side of the swivel 30 may remain stationary.
For example, as shown in FIG. 1, the first driving device 211 further includes a first driving plate 2112, and the first driving plate 2112 is connected to the roller 40 to drive the roller to rotate. For example, the first drive plate 2111 may be fixedly disposed with the drive shaft 2111.
In the coiled tubing pipe bender provided by the embodiment of the disclosure, the transmission shaft also plays a role in supporting the roller. For the roller wound with the coiled tubing, the weight of the roller can reach dozens of tons, so that the bearing capacity of the transmission shaft is higher. In order to improve the bearing capacity of the transmission shaft, for example, the transmission shaft can be made of high-strength structural alloy steel and the like through a corresponding heat treatment process. Of course, the embodiments of the present disclosure do not limit specific parameters such as the material and structural strength of the transmission shaft.
In some examples, a first end 2111a of drive shaft 2111 is connected to a first end 30a of rotary joint 30 by a union, and a second end 2111b of drive shaft 2111 is connected to first manifold 50 by a union. The union connection has better connection convenience and universality. Of course, the transmission shaft 2111 and the rotary joint 30 and/or the first manifold 50 may be connected by other connection methods such as a thread, a clip, and the like, and the embodiment of the disclosure is not limited thereto.
In some examples, as shown in fig. 1, the first bracket 21 and the second bracket 22 are configured to be relatively movable in an axial direction (X direction) of the transmission shaft 2111. In this manner, the distance in the X direction of the first bracket 21 and the second bracket 22 can be adjusted so that both brackets can be adapted to various sizes of rollers.
For example, as shown in fig. 1, the first bracket 21 is a fixed bracket fixed on the base 10, the second bracket 22 is a sliding bracket slidably connected to the base 10, and the second bracket 22 can slide along the X direction in the figure to be close to or far from the first bracket 21. For example, a slide rail is disposed on the base 10, and a connecting portion slidably engaged with the slide rail is disposed on the second bracket 22, so that the second bracket 22 can slide along the slide rail on the base. For another example, the second bracket 22 and the base 10 may be screwed to adjust the position of the second bracket 22 relative to the first bracket 21 in the X direction. Of course, embodiments of the present disclosure are not limited thereto. For example, the second holder 22 may be a fixed holder fixed to the base 10, and the first holder 21 may be a slide holder slidably connected to the base 10. For example, the first bracket 21 and the second bracket 22 may be both slide brackets and slidably connected to the base 10.
In some examples, as shown in fig. 1-3, the second support 22 includes a second drive device 221. The second driving device 221 is rotatably connected to the drum 40, and the first driving device 211 and the second driving device 221 are configured to drive the drum 40 to rotate.
In the coiled tubing lowering operation, the first driving device 211 and the second driving device 221 rotate simultaneously, and drive the roller 40 to rotate together to realize the pipe reversing function. The driving devices are arranged on the two sides of the roller, and the driving torque of the pipe bender can be obviously improved in a bilateral driving mode, so that the pipe bender can meet the pipe bender requirement of a large-capacity large-size heavy roller. For example, the first driving device 211 and the second driving device 221 may be driven by hydraulic pressure, pneumatic pressure, or electric pressure, and the embodiment of the disclosure is not limited thereto.
For example, as shown in fig. 1, the second driving device 221 is substantially symmetrically distributed in the X direction, and the second driving device 221 is provided with a second transmission disc 2212, similar to the first driving device 211. The first driving plate 2112 and the second driving plate 2212 are respectively used for connecting both sides of the drum to drive the drum to rotate.
In some examples, as shown in fig. 1-3, the coiled tubing reel further includes a support arm 70. As shown in fig. 2, the support arm comprises a first arm 71 and a second arm 72, a first end 711 of the first arm 71 is hinged to the base 10, and a second end 712 of the first arm 71 is hinged to a first end 721 of the second arm 72.
As shown in fig. 2, a first lifting device 73 is disposed between the first arm 71 and the base 10, and the first lifting device 73 is configured to drive the first arm 71 and the base 10 to rotate relatively. The first arm 71 and the second arm 72 have a second lifting device 74 therebetween, and the second lifting device 74 is configured to drive the first arm 71 and the second arm 72 to rotate relatively.
For example, the first lifting device 73 and the second lifting device 74 may be hydraulic cylinders. The first arm 71 and the second arm 72 can be folded or unfolded by the extension and contraction of the hydraulic cylinders to adjust the dimensions of the support arm 70 in the Y direction and the Z direction. Of course, the first lifting device 73 and the second lifting device 74 may also be other power devices, such as a pneumatic, electric or manual telescopic device, and the embodiment of the disclosure is not limited thereto.
In coiled tubing calandria operation, need to expand the support arm to increase the vertical height of support arm to adapt to big size cylinder operation. However, in the deployed position, the height of the support arm may exceed the dimensions permitted for road traffic, and therefore the support arm may be folded during transport to reduce the vertical height of the support arm. Due to the double folding function of the support arm 70, the support arm 70 can carry a large roller with an outer diameter of 220 inches and a width (dimension in the X direction) of 70 inches to 120 inches, for example.
Fig. 4 is a schematic plan view of the coiled tubing stripper of fig. 1 in the X-direction, and fig. 1 and 4 show the support arms in an expanded state. Fig. 5 is a further plan view of the coiled tubing reel, fig. 6 is a plan view of the coiled tubing reel of fig. 5 taken along the X-direction, and fig. 5 and 6 show the support arms in a folded state. Comparing fig. 1 and 5, it can be seen that the support arm 70 is significantly lower in height in the collapsed condition than in the expanded condition.
In some examples, as shown in fig. 1-3, the coiled tubing pig further comprises a pig 80 coupled to the second arm 72 of the support arm 70. The tube racker 80 includes a position adjustment mechanism 81 and a guide 82 provided at the position adjustment mechanism, and the position adjustment mechanism 81 is configured to adjust the position of the guide 82 in a direction parallel to the axis of the drive shaft 2111. For example, the position adjustment mechanism 81 may be a two-way screw mechanism, or a ball screw mechanism. For example, the guide 82 is used to guide the coiled tubing during racking operations. In the pipe arranging operation, along with the change of the position of the oil pipe in the X direction, the guide 82 can correspondingly move, so that the guide and the oil pipe are prevented from being dislocated, and the pipe arranging is ensured to be orderly.
For example, as shown in fig. 2, the number of the support arms 70 may be two, and the two support arms 70 are symmetrically distributed along the X direction. The tube racker 80 is connected between the second ends 722 of the two second arms 72. The two support arms support the pig 80 more firmly.
In some examples, as shown in fig. 4 and 6, the coiled tubing pipe stripper is provided with a first stopper rod 13 and a second stopper rod 14. As shown in fig. 6, when the support arm is in the folded state, the first stopper rod 13 is used for supporting and stopping the first arm 71, and the second stopper rod 14 is used for supporting and stopping the second arm 72. For example, the first limiting rod 13 and the second limiting rod 14 may be disposed on the base 10, or may be disposed at other positions of the coiled tubing pipe stripper.
In some examples, as shown in fig. 4 and 6, the base 10 includes a first leg 11 extending in a first direction. The first leg 11 can increase the supporting stability of the pipe bender in the Z direction. The first direction is parallel to the plane of the base 10 (i.e., the XZ plane) and forms a non-zero angle with the extending direction of the transmission shaft 2111, and the first leg is configured to slide in the first direction with respect to the base 10. For example, the first leg may slide telescopically in the base 10. In fig. 4 and 6, the first direction coincides with the Z direction, but the embodiment of the present disclosure is not limited thereto, and as long as the first direction does not coincide with the X direction, the length of the base in the Z direction may be increased when the first leg 11 is extended, thereby improving the support stability.
For example, as shown in fig. 4 and 6, the first leg 11 can be extended and retracted in the Z direction in the frame of the base 10, and the power for the extension and retraction can be mechanical, hydraulic, electric, pneumatic, and the like. The end of the first leg 11 is provided with a first mechanical leg 111 capable of adjusting height up and down, and the height is adjusted during operation to find a proper supporting point on the ground, so as to achieve an auxiliary supporting mode.
In some examples, as shown in fig. 4 and 6, the base 10 further includes a second leg 12 disposed opposite the first leg 11, i.e., on the other side of the base 10 in the Z direction. The second leg 12 is configured to be flipped relative to the base 10 to change the length of the second leg 12 in the first direction. The second leg 12 can further increase the supporting stability of the pipe bender in the Z direction.
For example, the second leg 12 may be inverted in the XZ plane, with FIGS. 4 and 6 showing the second leg in an extended position, increasing the length of the base in the Z direction. When folded, the second support leg can be attached to the edge beam of the base 10, the edge beam is provided with a clamping structure for fixing the second support leg, and the space occupation can be reduced after folding. For another example, the second leg 12 may also be flipped in the YZ-plane, which may also increase the length of the base in the Z-direction.
For example, as shown in fig. 4 and 6, the end of the second leg 12 is provided with a second mechanical leg 121 capable of adjusting the height up and down, and the height is adjusted to find a proper supporting point on the ground during operation, so as to serve as an auxiliary supporting mode.
In some examples, as shown in fig. 1-3, the coiled tubing pig further includes a control device 100 and a hydraulic and electrical wiring plug 110. The hydraulic and electrical connector pins 110 are used to connect external power equipment, such as a hydraulic motor or an electric motor, to drive the first drive device 211. The control device 100 is, for example, a switch, and is used to control operations such as start and stop of the first driving device 211.
When the coiled tubing works, the coiled tubing pipe bender is connected with external power equipment for use, and the external power equipment is connected with the hydraulic and electric wiring plug 110 of the pipe bender through a connecting pipeline, so that the functions of the coiled tubing working roller and the pipe bender are realized.
In some examples, as shown in fig. 1-3, the coiled tubing pig further comprises a remote control 90. The remote control device 90 is communicatively coupled to the first drive device 211 and is configured to remotely control the movement of the first drive device 211. The remote control device 90 and the first driving device 211 may be connected by a cable, a hydraulic line, or a wireless signal, which is not limited in the disclosure.
When the tube rewinder is provided with the second driving means 221, the remote control device 90 may also be in communication with the second driving means 221 to control the movement of the second driving means 221 at the distal end. The remote control device 90 may be, for example, a control switch of the first driving device 211 and/or the second driving device 221.
It should be noted that, in fig. 1, the remote control device 90 is placed on the base 10 only as an example, and may be placed at this position or other positions during transportation. During racking operations, the remote control 90 may be placed at the remote end of the racker to improve safety of the field operations.
