Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling equipment, in particular to a power catwalk and a remote-controlled pressure-operating system. Background Art

[0002] Well repair is an important part of the construction process of oil and gas exploration and development. The pressure operation system is an advanced downhole operation method that keeps the wellbore in a certain pressure state and disassembles and installs pipes without killing the well or releasing the pressure. Pressure operation can protect and maintain the original production capacity of the formation, reduce the number of production-increasing measures such as acid fracturing, and provide a good foundation for the long-term development and stable production of oil and gas fields.

[0003] When the pressurized operation system is working, the transportation of pipe strings is an indispensable part of the pressurized operation. The existing hydraulic catwalks for transporting pipe strings are relatively inefficient. For example, the Chinese utility model patent with publication number CN217712460U discloses a safe and efficient hydraulic catwalk. When the pipe strings on the pipe rack need to be moved to the catwalk transportation track, manual handling or manual intervention is still required to enable the pipe strings to enter the catwalk transportation track, resulting in low construction efficiency and certain safety risks. Utility Model Content

[0004] The utility model aims to overcome the problem of low construction efficiency in the existing pressure operation system, in which manual handling or manual intervention is still required for the pipe string to enter the catwalk transport track from the pipe rack, and to provide a power catwalk and remotely controlled pressure operation system.

[0005] In a first aspect, the utility model provides a power catwalk, comprising a main body base, a transport track being installed on the main body base, a pipe rack being installed on at least one side of the main body base, a sliding shoe being installed on the transport track, the sliding shoe being able to slide on the transport track, an end of the pipe rack close to the main body base being a first end, an end of the pipe rack away from the main body base being a second end, the first end being hinged to the main body base, and a hydraulic support leg being installed on the second end, and the hydraulic support leg being used to drive the second end to rise and fall.

[0006] The power catwalk provided by the utility model is provided with a first end of the pipe rack being hinged to the main body base, and the hydraulic legs can drive the second end to rise or fall, so that the pipe rack as a whole can swing up and down around the hinge point to achieve the tilt of the pipe rack. When the second end is raised, the pipe column placed on the pipe rack can automatically slide into the transport track without manual handling or intervention, reducing the possibility of casualties, significantly improving the efficiency of the pipe column entering the transport track from the pipe rack, and shortening the operation time.

[0007] Optionally, the main body base is also equipped with a pipe inlet assembly, which is used to push the pipe column adjacent to the transport track into the transport track. The pipe inlet assembly includes a base, and the base is equipped with a pipe push component, which can perform linear reciprocating motion in the vertical direction.

[0008] With this structural setting, the pipe pushing component can make linear reciprocating motion in the vertical direction, for example, the pipe pushing component is driven to rise or fall by a hydraulic cylinder or a pneumatic cylinder. When the pipe column is not needed to enter the transport track, the pipe pushing component can be lowered, and the top of the pipe pushing component does not exceed the upper end surface of the pipe rack at this time, and does not affect the parking of the pipe column on the pipe rack; when the pipe column needs to be pushed into the transport track, the pipe pushing component can be raised, and the pipe pushing component pushes the pipe column upward. Since the hydraulic support leg is also raised upward at this time, that is, the height of the second end is higher than the height of the first end, the pipe column is easier to slide or roll into the transport track, further improving the efficiency of the pipe column entering the transport track from the pipe rack and shortening the operation time.

[0009] Optionally, the pipe pushing component includes a first inclined surface, the angle between the first inclined surface and the horizontal plane is an acute angle, and the first inclined surface is used to guide the pipe column to enter the transport track.

[0010] With this structural setting, the angle between the first inclined plane and the horizontal plane is an acute angle, that is, the first inclined plane is inclined toward the transport track, which is more conducive to the automatic sliding of the pipe column into the transport track, making the pipe column smoother when sliding or rolling into the transport track, reducing resistance, and further improving the efficiency of the pipe column entering the transport track.

[0011] Optionally, the push tube component comprises a first protrusion, and the first protrusion is used to prevent the pipe column entering the push tube component from rolling back.

[0012] With this structural arrangement, the first protrusion can effectively prevent the pipe string from rolling back after entering the pipe pushing component, thereby eliminating potential safety hazards and improving the safety of pipe string transportation.

[0013] Optionally, the first protrusion is wedge-shaped.

[0014] With this structural setting, the first protrusion can be set as a wedge-shaped protrusion that gradually narrows from bottom to top. When the pipe columns are arranged on the pipe rack, they can be better inserted into the gaps between the pipe columns and quickly move the pipe columns into the pipe pushing component.

[0015] Optionally, the base is also equipped with a blocking tube component, which is closer to the transport track than the pushing tube component. The blocking tube component includes a blocking rod and a hinged seat. The hinged seat is fixedly connected to the base, and the blocking rod is hinged to the hinged seat. The blocking rod can swing within the range of 0° to 90°.

[0016] With this structural arrangement, when the pipe column does not need to be moved into the transport track, the blocking rod can be adjusted to a vertical state to prevent the pipe column from sliding into the transport track. When the pipe column needs to be moved into the transport track, the blocking rod can be adjusted to a horizontal state without affecting the pipe column from entering the transport track.

[0017] Optionally, the distance between the blocking rod and the first protrusion is the diameter distance of a pipe column.

[0018] With this structural setting, a space that can just accommodate a pipe column is formed between the blocking rod and the first protrusion. When a pipe column needs to be moved into the transport track, the pipe pushing component rises, the blocking rod changes from a vertical state to a horizontal state, and the first protrusion can just be inserted into the gap between the first pipe column and the second pipe column close to the transport track, preventing multiple pipe columns from sliding into the transport track at the same time. For pipe columns of different diameters, only the distance between the blocking rod and the first protrusion needs to be adjusted to adapt to pipe columns of different specifications, thereby improving the adaptability of the power catwalk.

[0019] Optionally, the number of the pipe racks is four, and the pipe racks are arranged in pairs on both sides of the main base.

[0020] With this structural setting, pipes can be arranged on both sides of the main base, which improves the pipe transmission efficiency of the power catwalk. At the same time, the left-right symmetrical design also improves the overall structural stability of the power catwalk.

[0021] Optionally, the transport track is a V-shaped groove structure.

[0022] With this structural setting, the transport track with a V-shaped groove structure can facilitate the transportation of the pipe string and prevent the pipe string from accidentally falling off the track during transportation.

[0023] In the second aspect, the utility model provides a remote-controlled pressure-operating system, including a pressure-operating machine, a pipe lifting device and the above-mentioned power catwalk, wherein the power catwalk is arranged on one side of the pressure-operating machine, the pipe lifting device is connected to the pressure-operating machine, and the pipe lifting device is used to receive and deliver the pipe string between the power catwalk and the pressure-operating machine; the pressure-operating machine is used to disassemble or install the pipe string in the wellbore under pressure.

[0024] The remote-controlled pressure-operating system provided by the utility model utilizes the power catwalk provided by the utility model. The pipe columns placed on the pipe rack can automatically slide into the transport track without manual handling or intervention, thereby reducing the possibility of casualties and accidents, significantly improving the efficiency of the pipe columns entering the transport track from the pipe rack, and shortening the operation time.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] 1. The power catwalk provided by the utility model is provided with a first end of the pipe rack being hinged to the main body base, and the hydraulic legs can drive the second end to rise or fall, so that the pipe rack as a whole can swing up and down around the hinge point to achieve the tilt of the pipe rack. When the second end is raised, the pipe column placed on the pipe rack can automatically slide into the transport track without manual handling or intervention, reducing the possibility of casualties, significantly improving the efficiency of the pipe column entering the transport track from the pipe rack, and shortening the operation time.

[0042] Example 1

[0043] like Figure 1 , Figure 2 As shown, this embodiment provides a power catwalk that can transport pipe strings during pressure operations.

[0044] The power catwalk includes a main body base 1, which is fixed to the ground. A transport track 2 is installed above the main body base 1. The transport track 2 can be a V-shaped groove structure to facilitate the transportation of pipe columns and prevent the pipe columns from accidentally falling off the track during transportation. A pipe rack 3 is installed on at least one side of the main body base 1. The pipe rack 3 can be symmetrically arranged on the left and right sides of the main body base 1. Preferably, the number of the pipe racks 3 is four, and the pipe racks 3 are arranged on both sides of the main body base 1 in pairs, that is, Figure 2 As shown, two pipe racks 3 are arranged on the left side of the main base 1, and two pipe racks 3 are arranged on the right side of the main base 1. The positions of the pipe racks 3 on the left and right sides correspond to each other, so that the pipe columns to be transported can be placed on the two pipe racks 3 on the left side of the main base 1. Similarly, the pipe columns to be transported can also be placed on the two pipe racks 3 on the right side of the main base 1, which improves the pipe transfer efficiency of the power catwalk. At the same time, the left-right symmetrical design also improves the overall structural stability of the power catwalk.

[0045] When the power catwalk is in use, the end close to the pressure working machine is connected to the vertical support, and the vertical support is used to vertically transport the transported pipe column. The end of the transport track 2 away from the vertical support is installed with a sliding shoe 4 and a motor 8. The transmission chain 7 is installed in the transport track 2. The sliding shoe 4 is connected to the motor 8 through the transmission chain 7. The motor 8 drives the chain 7 to drive, and then drives the sliding shoe 4 to slide back and forth on the transport track 2. When in use, one end of the transported pipe column is placed on the sliding shoe 4, and the other end is grabbed by the jacking trolley as in the prior art. The jacking trolley can move upward along the vertical support. The jacking trolley cooperates with the sliding shoe 4 to adjust the pipe column from a horizontal state to a vertical state and transport it to the operating platform of the pressure working machine.

[0046] The end of the pipe rack 3 close to the main body base 1 is the first end, and the end of the pipe rack 3 away from the main body base 1 is the second end. The first end is hinged to the main body base 1, and the second end is installed with a hydraulic leg 5. The hydraulic leg 5 is hinged to the second end. The hydraulic cylinder of the hydraulic leg 5 rises to drive the second end to rise, and the hydraulic cylinder of the hydraulic leg 5 retracts to drive the second end to fall. This arrangement allows a single pipe rack 3 to independently swing up and down with the connection between the first end and the main body base 1 as the hinge point, so that the pipe rack 3 can freely switch between a horizontal state, an inclined state toward the transport track 2 (the height of the second end is higher than the height of the first end), and an inclined state in the opposite direction of the transport track 2 (the height of the second end is lower than the height of the first end).

[0047] The power catwalk may also be equipped with a control cabinet, the input end of which is electrically connected to an external power source, and the operation of the power catwalk may be controlled through the control cabinet.

[0048] The power catwalk provided in this embodiment is provided with a first end of the pipe rack 3 being hinged to the main body base 1, and the hydraulic legs 5 can drive the second end to rise or fall, so that the pipe rack 3 as a whole can swing up and down around the hinge point to achieve the tilt of the pipe rack 3. When the second end is raised, the pipe column placed on the pipe rack 3 can automatically slide into the transport track 2 without manual handling or intervention, reducing the possibility of casualties, significantly improving the efficiency of the pipe column entering the transport track 2 from the pipe rack 3, and shortening the operation time.

[0049] Example 2

[0050] Based on Example 1, the power catwalk provided in this embodiment also includes an inlet pipe assembly 6, which is installed on the main base 1. Preferably, the inlet pipe assembly 6 can be installed near the hinge point between the first end and the main base 1. The inlet pipe assembly 6 is used to push the pipe column adjacent to the transport track 2 into the transport track 2.

[0051] like Figure 3-Figure 5 As shown, the pipe inlet assembly 6 includes a base 61, on which a pipe push component 62 and a hydraulic cylinder 64 are installed. The fixed end of the hydraulic cylinder 64 is fixedly installed on the base 61, and the movable end of the hydraulic cylinder 64 is fixedly connected to the pipe push component 62. The movable end of the hydraulic cylinder 64 can extend or retract in the vertical direction, thereby driving the pipe push component 62 to perform linear reciprocating motion in the vertical direction.

[0052] With this structural arrangement, the pipe push component 62 can perform linear reciprocating motion in the vertical direction, for example, the pipe push component 62 is driven to rise or fall by the hydraulic cylinder 64 or the air cylinder. When the pipe column is not required to enter the transport track 2, the pipe push component 62 can be lowered, and at this time, the top of the pipe push component 62 does not exceed the upper end surface of the pipe rack 3, and does not affect the parking of the pipe column on the pipe rack 3; when the pipe column needs to be pushed into the transport track 2, the pipe push component 62 can be raised, and the pipe push component 62 pushes the pipe column upward. Since the hydraulic support leg 5 is also raised upward at this time, that is, the height of the second end is higher than the height of the first end, the pipe column is easier to slide or roll into the transport track 2, further improving the efficiency of the pipe column entering the transport track 2 from the pipe rack 3, and shortening the operation time.

[0053] Further, such as Figure 6As shown, the pipe pusher component 62 includes a first inclined surface 621, and the angle between the first inclined surface 621 and the horizontal plane is an acute angle, that is, the first inclined surface is inclined toward the transport track 2, and the first inclined surface 621 is used to guide the pipe column into the transport track 2. This structural setting is more conducive to the automatic sliding of the pipe column into the transport track 2, so that the pipe column slides or rolls into the transport track 2 more smoothly, reduces resistance, and further improves the efficiency of the pipe column entering the transport track 2.

[0054] Furthermore, the push tube component 62 further includes a first protrusion 622, such as Figure 3 , Figure 6 As shown, the first protrusion 622 can be arranged on the side of the first inclined surface 621 away from the transport track 2. The first protrusion 622 can be arranged in an upward wedge shape, and the first protrusion 622 is used to prevent the pipe column entering the push pipe component 62 from rolling back.

[0055] The first protrusion 622 can effectively prevent the pipe string from rolling back after entering the pipe pushing component 62, eliminating potential safety hazards and improving the safety of pipe string transportation. The first protrusion 622 is configured as a wedge-shaped protrusion that gradually narrows from bottom to top. When the pipe string is arranged on the pipe rack 3, it can be better inserted into the gap between the pipe strings and quickly move the pipe string into the pipe pushing component 62.

[0056] Example 3

[0057] On the basis of Example 2, the inlet pipe assembly 6 provided in this embodiment further includes a pipe blocking component 63, such as Figure 3-Figure 5 , Figure 7 As shown, the pipe blocking component 63 is installed on the base 61, and the pipe blocking component 63 is closer to the transport track 2 than the push pipe component 62. Figure 7 As shown, the blocking tube component 63 may specifically include a blocking rod 631, an articulated seat 632, a blocking pin 633, a mounting seat 634 and a blocking block 635. The articulated seat 632 is fixedly mounted on the base 61. The articulated seat 632 can be set as two relatively arranged mounting ears, and the blocking pin 633 is fixedly mounted between the mounting ears. The blocking block 635 is hinged to the mounting ears through a pin shaft. The mounting seat 634 is fixedly mounted on the upper part of the blocking block 635, and the blocking rod 631 is fixedly mounted on the upper part of the mounting seat 634. The blocking block 635 swings between the two mounting ears. When the blocking pin 633 contacts the blocking block 635, it can prevent the blocking block 635 from continuing to swing, thereby controlling the blocking rod 631 to swing within the range of 0° to 90°.

[0058] With this structural setting, when the pipe column does not need to be moved into the transport track 2, the blocking rod 631 can be adjusted to a vertical state to prevent the pipe column from sliding into the transport track 2. When the pipe column needs to be moved into the transport track 2, the blocking rod 631 can be adjusted to a horizontal state without affecting the pipe column from entering the transport track 2.

[0059] Furthermore, a plurality of mounting holes 636 at different positions can be opened on the upper portion of the mounting seat 634, and the blocking rod 631 is threadedly connected to the mounting hole 636. By selecting different mounting holes 636 to install the blocking rod 631, the distance between the blocking rod 631 and the first protrusion 622 can be more reasonably selected. Preferably, the distance between the blocking rod 631 and the first protrusion 622 is the diameter distance of a pipe column.

[0060] With this structural setting, a space that can just accommodate a pipe column is formed between the blocking rod 631 and the first protrusion 622. When a pipe column needs to be moved into the transport track 2, the pipe pushing component 62 rises, the blocking rod 631 changes from a vertical state to a horizontal state, and the first protrusion 622 can just be inserted into the gap between the first pipe column and the second pipe column close to the transport track 2, preventing multiple pipe columns from sliding into the transport track 2 at the same time. For pipe columns of different diameters, it is only necessary to adjust the distance between the blocking rod 631 and the first protrusion 622 to adapt to pipe columns of different specifications, thereby improving the adaptability of the power catwalk.

[0061] Preferably, the push pipe component 62 can be hinged with the stopper 635. When the hydraulic cylinder 64 pushes the push pipe component 62 to rise, the push pipe component 62 drives the stopper 635 to rotate, thereby driving the stopper 631 from a vertical state to a horizontal state, so as to facilitate the pipe column to enter the transport track 2. When the hydraulic cylinder 64 drives the push pipe component 62 to fall, the push pipe component 62 drives the stopper 635 to rotate, thereby driving the stopper 631 from a horizontal state to a vertical state, thereby preventing the next pipe column from sliding into the transport track 2. Of course, it is foreseeable that an independent driving component can also be provided for the stop pipe component 63, such as a hydraulic cylinder, a gas cylinder, an electric cylinder, etc., to drive the stopper 631 to swing within a range of 0° to 90°.
