Description

Technical Field

[0001] This invention relates to the field of oilfield pressurized equipment technology, and in particular to a simple pipe laying method and device for automating pressurized operations. Background Technology

[0002] As a key link in ensuring the efficient operation of oil wells in the mid-to-late stages of oil and gas field development, pressurized operations eliminate the need for well control or blowout treatment. They can complete well maintenance and reservoir stimulation operations while maintaining stable pressure within the wellbore. This avoids contamination of the reservoir by well control fluids, reduces waste of oil and gas resources, and significantly shortens the operation cycle. It plays an irreplaceable role in maintaining stable well production in the mid-to-late stages and improving overall development efficiency. Therefore, its application in the current oil and gas extraction field is becoming increasingly widespread.

[0003] Before conducting pressurized operations, the tubing needs to be lowered into the well. The process is roughly as follows: First, the tubing is transported by transport vehicles and stacked next to the well. Then, one tubing is lifted and lowered into the well, followed by another tubing, which is then hooked together with pipe wrenches. This process of lifting, hooking, and lowering tubing is repeated until the tubing is in the correct position. When it is necessary to remove the tubing, it is lifted upwards and secured to the wellhead. Then, the upper tubing is removed using pipe wrenches and stacked. Finally, this process of lifting, removing, and stacking tubing is repeated until all tubing is removed from the well.

[0004] Chinese patent application CN119711964A, published on March 28, 2025, discloses an automated live-line working machine, including a live-line working machine body. A telescopic robotic arm is mounted on one side of the live-line working machine body, a lifting frame is mounted on one side of the telescopic robotic arm, and a gripping frame is mounted on one side of the lifting frame. The gripping frame is powered by a hydraulic pump and has two sections. A pipe-gripping assembly is mounted on one side of the gripping frame for clamping pipes. The pipe-gripping assembly includes several mounting slots, all located on one side of the gripping frame. A fixing frame is fixedly fitted inside each mounting slot, and a hydraulic rod is fixedly mounted on one side of the inside of each mounting slot. A pusher frame is fixedly installed at one end of the telescopic rod. A first gripper and a second gripper are respectively provided on one side of the pusher frame. The first gripper and the second gripper are arranged at intervals relative to each other. A connecting foot is fixedly installed on one side of the first gripper, and two cross feet are fixedly installed on one side of the second gripper. An I-frame is provided inside the pusher frame. A connecting column is movably sleeved inside the I-frame. The other end of the I-frame is movably sleeved with the connecting foot. The connecting foot and the connecting column are respectively located between the two cross feet. The two sets of pipe gripping components are combined to form a mechanical pipe gripper. The distance between the two sets of pipe gripping components is 2.5 meters. The pipe gripping mechanism consists of a pipe gripper hand and a straightening hand. The pipe gripper hand has a floating function. The pipe gripping components have the function of synchronizing the angle with the catwalk.

[0005] The automated live-line working machine disclosed in this patent application uses a hydraulic rod to drive a pusher frame and a jig frame to move, causing the first and second grippers to move closer together to form a mechanical pipe gripper, which can automatically grab and flip tilted pipe columns. However, the overall structure is complex, relies on a hydraulic system and precision mechanical components, and has poor operational flexibility and reliability, affecting work efficiency. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this invention provides a simple pipe-laying method and device for automated pressurized operations. By controlling the tilt angle of the upper support arm, this invention realizes the automatic rolling and orderly stacking of oil pipes, which significantly improves the automation level and operation efficiency of the loading and unloading process. The oil pipes are supported in layers by a detachable U-shaped bracket, which has a simple structure and is flexible and reliable in operation, and improves the neatness of the oil pipe stacking.

[0007] This invention is achieved through the following technical solution: A simplified pipe-laying method for automating live-line operations includes the following steps: Step S1: Keep the unloading side and loading side of the upper support arm flush. When loading, the servo electric cylinder drives the upper support arm to tilt to the unloading side. Step S2: Place the oil pipe on the bearing surface of the upper bearing arm; Step S3: After the bottom layer of oil pipes is placed, install a U-shaped bracket on the guide column and support the bottom layer of oil pipes on the U-shaped brackets through the oil pipe placement pipe. Continue to place the oil pipes from the unloading side to the loading side in sequence to the upper layer. Step S4: Repeat step S3 until the oil pipes are stacked and the servo electric cylinder drives the upper support arm to return to a horizontal state. Step S5: During material feeding, the servo electric cylinder drives the upper support arm to tilt downwards again. Step S6: Starting from the top layer, take out the oil pipes closest to the material feeding side in sequence, and use the tilt angle to make the inner oil pipes automatically roll outward to replenish. Step S7: After one layer of tubing is removed, remove the corresponding tubing placement pipe and U-shaped bracket for that layer, and then continue to remove the tubing for the next layer. Step S8: Repeat step S7 until all oil pipes are removed, and then use the servo electric cylinder to drive the upper support arm back to a horizontal state.

[0008] In step S1, tilting to the lower material side means that the height of the upper material side of the upper support arm is higher than the height of the lower material side.

[0009] In step S2, when placing the oil pipes, the oil pipes are arranged sequentially from the unloading side to the upward loading side along the bearing surface of the upper bearing support arm.

[0010] In step S3, the oil pipe placement pipe is used to support the single-layer oil pipe, and the oil pipe placement pipe is suspended on the guide column by the U-shaped brackets on both sides of the upper support arm.

[0011] In step S6, each pipe retrieval operation starts from the topmost oil pipe that is closest to the material feeding side, and the subsequent oil pipe automatically rolls down to the retrieval position by relying on the tilt angle.

[0012] In step S7, the oil pipe placement pipe and U-shaped bracket are removed in the order of removing them from the top layer to the bottom layer.

[0013] A simple pipe-laying device for automated pressurized operations includes a loading and unloading mechanism, a connecting bracket, and a control box. Two loading and unloading mechanisms are connected by the connecting bracket. Each loading and unloading mechanism includes a lower support base, an upper support arm, a storage rack, and a tilt adjustment component. The tilt adjustment component is located between the lower support base and the upper support arm, with one end hinged to the upper support arm and the other end connected to the lower support base. The storage rack is fixed to the upper support arm. The control box is electrically connected to the tilt adjustment component.

[0014] The tilt adjustment component includes a hinge seat located on one side of the lower support base and hinged to the upper support arm, a servo electric cylinder mounted on the lower support base, a slider located on the lower support base and moving along the length of the lower support base, and an inclined connecting rod hinged to the slider. The slider is connected to the servo electric cylinder, and the inclined connecting rod is hinged to the upper support arm.

[0015] The storage rack includes guide columns and oil pipe placement pipes. There are two guide columns, one of which is fixed on one side of the upper support arm and the other is fixed on the other side of the upper support arm. The guide columns have T-shaped grooves, and U-shaped brackets are slidably connected in the T-shaped grooves. The oil pipe placement pipes are placed on the U-shaped brackets.

[0016] An end cap guide plate is connected to the outer side of the guide column, and the end cap guide plate has a groove.

[0017] The lower support base has a sliding groove, and a roller is installed on the slider, with the roller located inside the sliding groove.

[0018] The beneficial effects of this invention are mainly reflected in the following aspects: 1. Compared with the prior art, the present invention realizes the automatic rolling replenishment and orderly stacking of oil pipes by controlling the tilt angle of the upper support arm, which significantly improves the automation level and operation efficiency of the loading and unloading process. The oil pipes are supported in layers by a detachable U-shaped bracket, which has a simple structure and flexible and reliable operation, and improves the stacking neatness of the oil pipes. 2. This invention clarifies the tilting method where the feeding side is higher than the unloading side, ensuring that the oil pipe can automatically roll to the unloading side under the action of gravity, reducing the need for manual intervention and making the pipe removal process smoother and more continuous. 3. This invention stipulates that the oil pipes are arranged sequentially from the unloading side to the loading side, establishing an orderly placement logic, which is conducive to subsequent automated pipe retrieval. This order, combined with the tilt angle, further optimizes the reliability and controllability of the oil pipe flow. 4. This invention adopts a sliding connection between a U-shaped bracket and a guide column, which facilitates flexible adjustment of the support position according to the height of the oil pipe layer. The oil pipe placement pipe provides stable support, enhancing the stability and safety of layered stacking.

[0019] 5. This invention specifies that pipe retrieval should begin from the top layer and closest to the material feeding side, making full use of the tilt angle to achieve automatic rolling and replenishment of the oil pipe, reducing downtime and waiting time, realizing the continuity of the pipe retrieval process, and improving work efficiency.

[0020] 6. In this invention, the oil pipe placement pipe and U-shaped bracket are removed layer by layer from top to bottom, which ensures that the lower oil pipe is always supported, avoids structural instability, and the sequential disassembly improves operational safety and facilitates on-site management.

[0021] 7. This invention connects two loading and unloading mechanisms side by side via a connecting bracket, enabling simultaneous processing of multiple rows of oil pipes, thereby improving overall operating capacity and efficiency. The tilt adjustment component enables precise angle control of the upper support arm, providing a foundation for automated loading and unloading.

[0022] 8. This invention uses a servo electric cylinder to drive the slider and tilting link, which realizes a smooth and precise adjustment of the tilt angle of the upper support arm. The structure is reliable and easy to control, and can adapt to the angle requirements under different working conditions.

[0023] 9. In this invention, the T-shaped groove on the guide column cooperates with the U-shaped bracket, allowing for flexible adjustment of the support height, which can adapt to the stacking of oil pipes of different diameters.

[0024] 10. In this invention, the groove of the end cap guide plate can limit the end of the oil pipe placement tube, so that the end of the oil pipe placement tube can only move up and down within the groove of the end cap guide plate, which can effectively prevent the oil pipe placement tube from falling off during loading, unloading and storage. 11. In this invention, the slider moves within the sliding groove via rollers, reducing motion friction and resistance, making tilt angle adjustment smoother and more durable, and enhancing the mechanical stability and long-term operational reliability of the entire device.

When loading, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the unloading side. Step S2: Place the oil pipe on the bearing surface of the upper bearing arm 1; Step S3: After the bottom layer of oil pipes is placed, install the U-shaped bracket 4 on the guide column 3, and support the bottom layer of oil pipes on the U-shaped bracket 4 through the oil pipe placement pipe 5.

Step S5: During material feeding, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the lower material side again. Step S6: Starting from the top layer, take out the oil pipes closest to the material feeding side in sequence, and use the tilt angle to make the inner oil pipes automatically roll outward to replenish. Step S7: After one layer of oil pipe is removed, remove the corresponding oil pipe placement pipe 5 and U-shaped bracket 4, and then continue to remove the oil pipe of the next layer. Step S8: Repeat step S7 until all oil pipes are removed, and then drive the upper support arm 1 to return to a horizontal state via the servo electric cylinder 2.

[0027] This embodiment is the most basic implementation method. Compared with the prior art, by controlling the tilt angle of the upper support arm 1, the automatic rolling and orderly stacking of oil pipes is realized, which significantly improves the automation level and operation efficiency of the loading and unloading process.

Example 2 See Figures 1-3 A simplified pipe-laying method for automated live-line work includes the following steps: Step S1: Keep the unloading side and loading side of the upper support arm 1 flush.

Continue to place the oil pipes from the unloading side to the upper loading side in sequence. Step S4: Repeat step S3 until the oil pipes are stacked and the servo electric cylinder 2 drives the upper support arm 1 to return to a horizontal state. Step S5: During material feeding, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the lower material side again. Step S6: Starting from the top layer, take out the oil pipes closest to the material feeding side in sequence, and use the tilt angle to make the inner oil pipes automatically roll outward to replenish. Step S7: After one layer of oil pipe is removed, remove the corresponding oil pipe placement pipe 5 and U-shaped bracket 4, and then continue to remove the oil pipe of the next layer. Step S8: Repeat step S7 until all oil pipes are removed, and then drive the upper support arm 1 to return to a horizontal state via the servo electric cylinder 2.

[0028] Preferably, in step S1, tilting to the lower material side means that the height of the upper material side of the upper support arm 1 is higher than the height of the lower material side.

[0029] In step S2, when placing the oil pipes, the oil pipes are arranged sequentially from the unloading side to the upward loading side along the bearing surface of the upper bearing support arm 1.

[0030] This embodiment is a preferred implementation method, which clearly defines the inclination method of the feeding side being higher than the unloading side, ensuring that the oil pipe can automatically roll to the unloading side under the action of gravity, reducing the need for manual intervention and making the pipe removal process smoother and more continuous. The oil pipes are arranged sequentially from the unloading side to the loading side, establishing an orderly placement logic that facilitates subsequent automated pipe removal. This order, combined with the tilt angle, further optimizes the reliability and controllability of the oil pipe flow. Example 3 See Figures 1-3 A simplified pipe-laying method for automated live-line work includes the following steps: Step S1: Keep the unloading side and loading side of the upper support arm 1 flush. When loading, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the unloading side. Step S2: Place the oil pipe on the bearing surface of the upper bearing arm 1; Step S3: After the bottom layer of oil pipes is placed, install the U-shaped bracket 4 on the guide column 3, and support the bottom layer of oil pipes on the U-shaped bracket 4 through the oil pipe placement pipe 5. Continue to place the oil pipes from the unloading side to the upper loading side in sequence. Step S4: Repeat step S3 until the oil pipes are stacked and the servo electric cylinder 2 drives the upper support arm 1 to return to a horizontal state. Step S5: During material feeding, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the lower material side again. Step S6: Starting from the top layer, take out the oil pipes closest to the material feeding side in sequence, and use the tilt angle to make the inner oil pipes automatically roll outward to replenish. Step S7: After one layer of oil pipe is removed, remove the corresponding oil pipe placement pipe 5 and U-shaped bracket 4, and then continue to remove the oil pipe of the next layer. Step S8: Repeat step S7 until all oil pipes are removed, and then drive the upper support arm 1 to return to a horizontal state via the servo electric cylinder 2.

[0033] In step S3, the oil pipe placement pipe 5 is used to support the single-layer oil pipe, and the oil pipe placement pipe 5 is suspended on the guide column 3 by the U-shaped brackets 4 on both sides of the upper support arm 1.

[0034] This embodiment is another preferred implementation method, which adopts a sliding connection between the U-shaped bracket 4 and the guide column 3, which facilitates flexible adjustment of the support position according to the height of the oil pipe layer. The oil pipe placement pipe 5 provides stable support, which enhances the stability and safety of layered stacking.

[0035] Example 4 See Figures 1-3 A simplified pipe-laying method for automated live-line work includes the following steps: Step S1: Keep the unloading side and loading side of the upper support arm 1 flush. When loading, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the unloading side. Step S2: Place the oil pipe on the bearing surface of the upper bearing arm 1; Step S3: After the bottom layer of oil pipes is placed, install the U-shaped bracket 4 on the guide column 3, and support the bottom layer of oil pipes on the U-shaped bracket 4 through the oil pipe placement pipe 5. Continue to place the oil pipes from the unloading side to the upper loading side in sequence. Step S4: Repeat step S3 until the oil pipes are stacked and the servo electric cylinder 2 drives the upper support arm 1 to return to a horizontal state. Step S5: During material feeding, the servo electric cylinder 2 drives the upper support arm 1 to tilt to the lower material side again. Step S6: Starting from the top layer, take out the oil pipes closest to the material feeding side in sequence, and use the tilt angle to make the inner oil pipes automatically roll outward to replenish. Step S7: After one layer of oil pipe is removed, remove the corresponding oil pipe placement pipe 5 and U-shaped bracket 4, and then continue to remove the oil pipe of the next layer. Step S8: Repeat step S7 until all oil pipes are removed, and then drive the upper support arm 1 to return to a horizontal state via the servo electric cylinder 2.

[0036] In step S1, tilting to the lower material side means that the height of the upper material side of the upper support arm 1 is higher than the height of the lower material side.

[0037] In step S2, when placing the oil pipes, the oil pipes are arranged sequentially from the unloading side to the upward loading side along the bearing surface of the upper bearing support arm 1.

[0038] In step S3, the oil pipe placement pipe 5 is used to support the single-layer oil pipe, and the oil pipe placement pipe 5 is suspended on the guide column 3 by the U-shaped brackets 4 on both sides of the upper support arm 1.

[0039] In a further preferred embodiment, in step S6, each pipe retrieval operation starts from the uppermost oil pipe closest to the material discharge side, and the subsequent oil pipe automatically rolls down to the retrieval position by relying on the tilt angle.

[0040] In step S7, the oil pipe placement pipe 5 and U-shaped bracket 4 are removed in the order of removing them from the top layer to the bottom layer.

[0041] This embodiment is another preferred implementation method, which stipulates that the pipe is taken from the top layer and closest to the material feeding side. The tilt angle is fully utilized to realize the automatic rolling of the oil pipe for replenishment, reduce downtime waiting time, realize the continuity of the pipe taking process, and improve the operation efficiency.

[0042] The removal of the oil pipe placement pipe 5 and U-shaped bracket 4 is carried out layer by layer from top to bottom, which ensures that the lower oil pipes are always supported, avoids structural instability, and the sequential disassembly improves operational safety and facilitates on-site management.

[0047] More preferably, the storage rack 9 includes guide columns 3 and oil pipe placement pipe 5. There are two guide columns 3, one guide column 3 is fixed on one side of the upper support arm 1, and the other guide column 3 is fixed on the other side of the upper support arm 1.

[0050] Example 7 See Figures 1-3 A simple pipe-laying device for automated pressurized operations includes a loading / unloading mechanism 6, a connecting bracket 7, and a control box 19. There are two loading / unloading mechanisms 6 connected by the connecting bracket 7. Each loading / unloading mechanism 6 includes a lower support base 8, an upper support arm 1, a storage rack 9, and an angle adjustment component 10. The angle adjustment component 10 is located between the lower support base 8 and the upper support arm 1.

[0052] The storage rack 9 includes guide columns 3 and oil pipe placement pipe 5. There are two guide columns 3. One guide column 3 is fixed on one side of the upper support arm 1, and the other guide column 3 is fixed on the other side of the upper support arm 1.

[0054] The lower support base 8 has a sliding groove 17, and the slider 12 is equipped with a roller 18, which is located in the sliding groove 17.

[0055] This embodiment is another preferred embodiment. The groove 16 of the end cap guide plate 15 can limit the end of the oil pipe placement tube 5, so that the end of the oil pipe placement tube 5 can only move up and down within the groove 16 of the end cap guide plate 15, which can effectively prevent the oil pipe placement tube 5 from falling off during loading, unloading and storage. The slider 12 moves within the sliding groove 17 via the roller 18, reducing motion friction and resistance, making tilt angle adjustment smoother and more durable, and enhancing the mechanical stability and long-term reliability of the entire device.

[0056] The basic principle of this invention is as follows: During loading, the servo electric cylinder 2 drives the upper support arm 1 to tilt towards the lower loading side, and the operator places the oil pipes sequentially from the lower loading side to the upper loading side. Each time a layer is filled, a U-shaped bracket 4 is installed on the guide columns 3 on both sides, and an oil pipe placement tube 5 is inserted to support the oil pipes of that layer, thus constructing a stable stacking structure that can be gradually increased in height. After all the oil pipes have been stacked in layers, the upper support arm 1 returns to a horizontal position, completing the storage preparation.

[0057] During unloading, the upper support arm 1 tilts again towards the unloading side, using gravity to automatically roll the oil pipes towards the unloading position. The unloading operation starts from the top layer, removing the outermost oil pipes one by one, with the subsequent oil pipes automatically rolling down to replenish them. When a layer is empty, the oil pipe placement pipe 5 and U-shaped bracket 4 of that layer are removed, and the upper support arm 1 remains tilted so that the next layer of oil pipes continues to be automatically replenished to the unloading position. This cycle continues until all oil pipes are removed.

[0058] The entire process, through simple tilt angle changes and detachable layered supports, achieves automated flow of oil pipe storage and retrieval.
