Description

The utility model relates to the oil and gas production industry, in particular to a device for laying and transporting well pipes, rods, equipment used in drilling oil and gas wells, as well as in their repair.

A device is known for laying borehole pipes during well construction and repair, comprising a frame, posts, receiving catwalks mounted on the posts, equipped with a container permanently installed under the catwalks and rigidly connected to the posts, accumulators made in the form of folding sections located on the sides of the receiving catwalk (patent RU No. 2138611, published 09/27/1999). The sections of one of the accumulators are equipped with troughs for draining process fluid, located under each section, the outermost of which is connected to the container, and the end of each previous trough in the working position overlaps the beginning of the next one.

The disadvantages of this device are: a narrow scope of application, since the device is effective in performing tripping operations during drilling and repair of wells, but is not intended for transporting well equipment; additional placement of the tank along the length of the walkway increases the metal consumption; the absence of limiters does not exclude the possibility of equipment rolling to the ground.

A known installation for accumulating and dispensing pump-compressor pipes and pump rods comprises a base in the form of sled-runners, a towing device, retractable wheel supports, right and left racks, a receiving chute, a working platform, wherein the left and right racks contain at least five rotary cargo legs, which are made of interconnected beams, two of which, acting as shelves of the rack, are made at an angle to each other and are hingedly connected to the upper supporting beam of the base of the sled-runners, and the third beam, for imparting rigidity to the structure and fixing with an inclination of 1-2° inward to the receiving chute, is located at an angle to the first two, and its length is selected in such a way that the end end with the support plate rests against the counter plate, which is fixed on the vertical post of the base runners (patent RU No. 88057, published. 27.10.2009).

The disadvantages are the complexity of the design and high metal consumption, a narrow scope of application, since the device is effective in performing lowering and lifting operations, but is not intended for transporting well equipment.

A device for laying downhole pipes and rods during drilling and well repair is known, comprising a frame with height-adjustable stands, accumulators fixed to the sides of the frame, having side stops and height-adjustable stands, a device for transportation (patent RU No. 34618, published 10.12.2003). The accumulator is made in the form of folding sections, a tray with the possibility of its movement along the height is installed on the frame, the folding sections are made in the form of folding beams, the frame and the device for its transportation are covered with a flooring made of a rigid permeable material, for example, a steel mesh or a metal covering with "friction type" holes.

The disadvantages of this device are a narrow scope of application due to the lack of a horizontal surface (due to folded supports) along the entire length of the frame in the folded (transport) position on the frame requires the use of additional transport for the delivery of long loads to and from the well (pump pipes, pump rods and/or the like), the complexity of the design associated with the installation of an additional controlled tray, pollution of the environment with oil sludge, paraffin, etc. from the pump pipes, pump rods, which flow down and penetrate through the flooring placed on the frame, made of a rigid permeable material, is not excluded.

Today, after underground well repair (UWR), there is always excess unused downhole pumping equipment (DPE) (pump pipes, pump rods, pipe wrenches, grips, etc.) left on the receiving platforms. Due to the lack of technical capability associated with the design flaws of the receiving platforms used, the UWR team unloads the DPE onto wooden pads before moving from the well and moves. It is necessary to "select" excess DPE using a unit for transporting rods, pipes, as well as personnel of TMS-Logistics LLC.

The closest in technical essence is a mobile device for laying pipes or rods during lowering and lifting operations in a well, including a frame on a transport device with height-adjustable stands for support on the ground in the working - extended - position, the length of all the stands is selected such that their upper ends in the working position rise above the frame to prevent pipes or rods from falling from the frame, storage units in the form of sliding sections symmetrically placed in the frame, flooring on the frame (patent RU No. 2813014, published 06.02.2024).

The rear posts are inserted into the transverse guides of the frame, and the side posts are equipped with telescopic beams consisting of hollow guides, into which rods with transverse channels for the corresponding posts are inserted, wherein the telescopic beams for the posts directed oppositely from the frame are made in pairs, rigidly connected in pairs along the lateral surface of the hollow guides, which are transversely, rigidly placed in the frame, the rods are made with the possibility of extending in pairs in opposite directions from the hollow guides of the telescopic beams, as well as with the possibility of fixing in the working position relative to the hollow guides, the length of all posts is selected such that their upper ends in the working position rise above the frame to prevent the pipes or rods from falling from the frame. The frame can be provided with a flooring in the form of runners for sliding pipes or rods, if available, they can be made removable and inserted with posts into technological openings in the frame, and removed during transportation. The technical solution expands the functional capabilities of the device by providing rigidity in the transverse direction from the frame in the working position and the horizontal surface along the entire length of the frame in the transport position, respectively, and also reduces the influence of the human factor when fixing against longitudinal movement of the frame due to rigid fixation by the rear supports against longitudinal movement in the working position.

The disadvantages are pollution of the environment during the operation of the device by pollution: oil sludge, paraffin, etc. from the tubing, pump rods, which fall on the soil when removing the flooring during transportation, as well as during technological operations at the well, accumulation of oil, paraffin, etc. on the flooring of the receiving bridge, the absence of limiters on the front part of the frame (from the drawbar side) from the movement of pipes, rods, equipment during movement, braking.

The technical result is the creation of a design for a mobile device for laying pipes or rods during tripping operations in a well, which allows for expanding the functional capabilities due to rigid fixation from longitudinal movement of pipes and rods, eliminating an emergency situation, in the transport position, eliminating environmental pollution when extracting pipes from a well, laying them and transporting them, improving the culture of production and labor safety, as well as eliminating the stagnation of oil, paraffin, etc. on the flooring of the receiving bridge.

The technical result is achieved by a mobile device for laying pipes or rods during tripping operations on a well, including a frame on a transport device with height-adjustable stands for support on the ground in the working - extended - position, the length of all the stands is selected such that their upper ends in the working position rise above the frame to prevent pipes or rods from falling from the frame, accumulators symmetrically placed in the frame, and a flooring on the frame.

What is new is that the front part of the frame has a drop-down side with a length equal to the width of the frame, the longitudinal part of the frame has side drop-down sides with a length of 1-1.5 m, wherein the side drop-down sides are located perpendicular to the drop-down side with the possibility of forming a pocket and fixing it from rolling and longitudinal movement of pipes or rods in the transport position, the drop-down sides are made of a rectangular metal sheet, secured to the frame with hinged joints, during transportation the drop-down sides are connected with a detachable joint, the flooring on the frame is made of metal steel sheets, in the front part of the frame a rectangular drainage hole is made on the flooring, a drainage tank is placed under the drainage hole, the rear end of the frame is equipped with a cable with ties.

The essence of the utility model is as follows.

A mobile device for laying pipes or pump rods (not shown) during tripping operations in a well comprises a rigid frame 1 (Fig. 1, 2) on a transport device (not shown in Fig. 1-3) with posts 2 (Fig. 2) adjustable in height for support on the ground in the working - extended - position, the length of all posts is selected such that their upper ends in the working position rise above the frame to prevent pipes or rods from falling from the frame, storage tanks 3 (Fig. 1, 2) can be made in the form of sliding sections or consist of collapsible sections symmetrically placed in frame 1, flooring 4 (Fig. 1) on the frame. The frame is made, for example, from longitudinal and transverse pipes welded together. The posts are made retractable, for example with clamps or in the form of a screw pair and are fixed on the accumulators in the center and at the end of the accumulator. On the front part of the frame 1 there is a folding side 5 (Fig. 1, 2, 3) with a length equal to the width of the frame. On the longitudinal part of the frame there are side folding sides 6 and 7 with a length of 1-1.5 m. The height of the folding sides 5, 6, 7 is made with the possibility of excluding the fall of pipes or rods during transportation. The folding sides 5, 6, 7 are made of a metal sheet 7 mm thick from rectangular rolled steel and are fixed on the frame with hinged joints. During transportation, the folding sides 5, 6, 7 are connected to each other with a detachable connection, for example, with clamps (pins) with cotter pins rigidly connected to the folding sides. The side boards 6, 7 are located perpendicularly relative to the rear board 5, forming a "pocket" that ensures rigid fixation against rolling and longitudinal movement of pipes, rods, eliminating an emergency situation, in the transport position. The frame is made with a length and width that does not exceed those permitted for vehicles on public roads. The flooring on the frame is made of metal steel sheets rigidly connected to each other and is rigidly fixed to the frame, with a length and width sufficient for performing work on the well and transportation. In the front part of the frame 1 on the flooring 4 there is a drainage hole 8 (Fig. 1) of a rectangular shape sufficient for collecting contaminants in a container 9 (Fig. 2). Drainage container 9 is located below the frame 1. Drainage container 9 is made of a rectangular shape sufficient for collecting contaminants, is located in the front part of the device on the drawbar side, fixed to the frame with 4 bolts. The drainage hole is used to clean and drain oil sludge, paraffin, etc. into a container for collecting contamination from the tubing and pump rods, eliminating environmental pollution during operation of the device at the well and during transportation. The rear open end of the side of the frame 1 of the receiving catwalk is equipped with a safety element, for example, a cable with ties 10, eliminating the rolling and slipping of the drilling and processing equipment (tubing, pump rods, etc.). The cable with ties 10 can be, for example, a flexible braided steel cable, fastened to the catwalk, connected when folded by "ears" welded to the ends of the main frame (not shown).

A mobile device for laying pipes and/or pump rods (not shown) is intended for receiving and delivering pump-compressor pipes, rods during routine and major repairs of wells, as well as for transporting drilling and processing equipment. The device consists of a frame 1, posts 2, storage units 3 in the form of sliding sections or collapsible sections, a flooring 4 - the receiving bridge itself, and a working platform with a railing (if any, not shown in Figs. 1-3). The device for transportation can be made in the form of a sled or a cargo trailer.

The receiving catwalks are brought into working position as follows. Before the GNO is extracted from the well, the mobile device for laying pipes or rods during tripping operations on the well is brought closer to the well. The quick-release add-on collapsible sections of the storage tanks or sliding sections of the storage tanks 3 are assembled and placed on the left and right along the sides of the frame, the supports 2 are installed and the drawbar is unhooked from the tractor. Then the mounted side folding sides 5, 6, 7 are unfolded, connected to each other by a detachable connection, for example, by clamps (pins) with cotter pins.

The tailboard 5 is made with a length equal to the width of the frame, the side tailboards 6, 7 are made with a length of 1-1.5 m. The tailboards 5, 6, 7 are made of rectangular metal sheet and are fixed to the frame with hinged joints. The tailboard 5 is folded onto the drawbar, and the side tailboards 6, 7 onto the storage tanks 3. Next, the rear additional cable with ties 10 is unhooked. Next, additional (if any) platforms (not shown) and an extension ladder are installed, the upper part of which is fixed to the structure (not shown). After completion of all preparatory work, including laying out the inventory and necessary equipment, the well repair stage begins (disassembling the wellhead equipment, folding back the SK balancer head, etc.). The extracted GNO from the well and placed on the flooring allows oil sludge, paraffin, etc. to flow onto the flooring. Then the pipes and rods are rolled onto the storage tank, and the flooring is cleaned, for example with a shovel, along the length of the flooring to the drainage hole 8 and sent to the drainage tank 9, ensuring that no contamination gets onto the soil. When contamination accumulates in the drainage tank, it is pumped out using a pump.

When the team moves to the next well, the transport of the scaffolds is carried out in assembled form by towing. The device is assembled in the reverse order. The folding sides are connected (see Fig. 3), the accumulators and racks are assembled. When transporting the GNO, the folding sides eliminate the possibility of rolling, moving forward pipes and rods, etc., eliminating the likelihood of an accident. The drawbar, using a support with a jack, allows you to hook the scaffolds to the towing hitch of the tractor (based on KAMAZ, URAL, tractor K-701, K-703, T-150, etc.) without using additional lifting devices.

The utility model allows to expand the functional capabilities due to rigid fixation from longitudinal movement of pipes, rods, eliminating an emergency situation, in the transport position, to eliminate pollution of the environment when extracting pipes from the well, their laying and transportation, to improve the culture of production and labor protection, and also to eliminate stagnation of oil, paraffin, etc. on the flooring of the receiving bridge.
