Description

Technical Field

[0001] This utility model belongs to the field of well workover rig technology, specifically relating to an integrated fast-moving electric-driven sand flushing workover rig. Background Technology

[0002] During oil well production, sand from the formation can enter the wellbore along with the oil and gas flow, depositing at the bottom and clogging the oil production channels. Sand flushing workover rigs inject high-pressure fluid into the well by running a sand flushing string, dispersing the sand and circulating it to the surface to ensure the wellbore remains unblocked.

[0003] Common sand flushing workover rigs typically consist of a vehicle body with a derrick mounted on it. A drill rope is attached to the derrick, and the end of the drill rope is connected to a sucker rod. Moving the vehicle body moves the sucker rod to the designated well for sand flushing and oil extraction. However, during workover operations, the vehicle body is prone to swaying, resulting in poor overall stability and affecting the rig's normal operation. Utility Model Content

The bottom of the main trailer 28 is equipped with wheels, a first support assembly, and a second support assembly. The first and second support assemblies are respectively located on the front and rear sides of the main trailer 28. The wheels are located between the first and second support assemblies and on the rear side of the main trailer 28. The front end of the main trailer 28... Used for connection with a tractor unit; the first support assembly includes two telescopic outriggers respectively located on the left and right sides of the main trailer 28; the second support assembly includes a left lateral telescopic cylinder 29, a left telescopic outrigger 30, a right lateral telescopic cylinder 31, and a right telescopic outrigger 32. The left and right lateral telescopic cylinders 29 and 31 are both horizontally positioned, while the left and right telescopic outriggers 30 and 32 are both vertically positioned, located on the left and right sides of the main trailer 28 respectively. The left and right lateral telescopic cylinders 29 and 31 are sequentially arranged along the length of the main trailer 28, and their telescopic directions are opposite. This structure, with the first and second support assemblies supporting the front and rear sides of the main trailer 28 respectively, improves the overall stability of the main trailer 28, ensuring the workover rig can operate normally. The front of the main trailer 28 is supported by two telescopic outriggers, while the rear is supported by wheels, a left telescopic outrigger 30, and a right telescopic outrigger 32. This further enhances the overall stability of the main trailer 28, ensuring the workover rig can operate normally. Furthermore, the left lateral telescopic cylinder 29 can drive the left telescopic outrigger 30 to extend or retract to the left, and the right lateral telescopic cylinder 31 can drive the right telescopic outrigger 32 to extend or retract to the right, increasing the distance between the left and right telescopic outriggers 30 and 32, thus further improving the overall stability of the main trailer 28. When the main trailer 28 moves, the outriggers retract to their initial positions. The left and right telescopic outriggers 30 and 32 retract first, and then the left and right lateral telescopic cylinders 29 and 31 respectively drive the outriggers 30 and 32 to retract to their initial positions, allowing the main trailer 28 to move normally.

[0023] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the left lateral telescopic cylinder 29 includes a first outer tube 291, a first inner tube 292, and a first telescopic sleeve 293. One end of the first inner tube 292 is fitted inside the first outer tube 291, and the other end extends outside the first outer tube 291 and is connected to the left telescopic support leg 30. The rear end of the first telescopic sleeve 293 is fixed to the inner wall of the first outer tube 291, and the front end of the first telescopic sleeve 293 is fixed to the inner wall of the first inner tube 292. The first telescopic sleeve 293 is used to drive the first inner tube 292 to extend or retract. With this structure, the first telescopic sleeve 293, as a driving component, can smoothly drive the first inner tube 292 to extend or retract along the first outer tube 291, thereby controlling the lateral movement of the left telescopic support leg 30 and improving the deployment and retraction efficiency of the support assembly.

[0024] In some embodiments of this application, such as Figure 3 , Figure 6 and Figure 9 As shown, the first telescopic sleeve 293 includes a first telescopic tube, a first telescopic rod, and a first oil supply pipe. The first telescopic rod is sleeved inside the first telescopic tube, and a first oil supply chamber is provided between the inner walls of the first telescopic rod and the first telescopic tube. The first oil supply pipe and the first oil supply chamber are connected. A first connecting rod is provided at the end of the first telescopic tube, and both ends of the first connecting rod are fixedly connected to the inner wall of the first outer tube 291. A second connecting rod is provided at the end of the first telescopic rod, and both ends of the second connecting rod are fixedly connected to the inner wall of the first inner tube 292. With this structure, hydraulic oil is transmitted through the first oil supply chamber and the first oil supply pipe, providing power for the telescopic movement. The first connecting rod and the second connecting rod respectively fix the first telescopic tube and the first telescopic rod to the first outer tube 291 and the first inner tube 292, so that the first telescopic sleeve 293 can smoothly drive the first inner tube 292 to telescopically move under hydraulic pressure, thereby controlling the lateral movement of the left telescopic outrigger 30.

[0025] In some embodiments of this application, such as Figure 6 , Figure 7 and Figure 9 As shown, a first oil supply connector is provided on the inner wall of the first outer pipe 291, and a second oil supply connector is provided on the left telescopic outrigger 30. A second oil supply pipe is also provided inside the first telescopic pipe. One end of the second oil supply pipe is connected to the first oil supply connector, and the other end is connected to the second oil supply connector. With this structure, the hydraulic oil circuit forms a continuous passage through the first oil supply connector, the second oil supply pipe, and the second oil supply connector, allowing hydraulic oil to be directly delivered from the first outer pipe 291 to the left telescopic outrigger 30.

[0026] In some embodiments of this application, such as Figure 3 and Figure 6As shown, the right lateral telescopic cylinder 31 includes a second outer tube 311, a second inner tube 312, and a second telescopic sleeve 313. One end of the second inner tube 312 is fitted inside the second outer tube 311, and the other end extends outside the second outer tube 311 and is connected to the right telescopic support leg 32. The first outer tube 291 and the second outer tube 311 are parallel to each other and fixedly connected. The rear end of the second telescopic sleeve 313 is fixed to the inner wall of the second outer tube 311, and the front end of the second telescopic sleeve 313 is fixed to the inner wall of the second inner tube 312. The second telescopic sleeve 313 is used to drive the second inner tube 312 to extend or retract. With this structure, the second telescopic sleeve 313 can drive the second inner tube 312 to extend or retract smoothly relative to the second outer tube 311, thereby controlling the lateral movement of the right telescopic support leg 32. The first outer tube 291 and the second outer tube 311 are fixedly connected in parallel, so that the horizontal telescopic cylinders on the left and right sides are structurally related and move in a coordinated manner. This helps to form a stable symmetrical support on the rear side of the main trailer 28 and improves the overall stability of the workover rig in operation.

[0027] In some embodiments of this application, such as Figure 3 , Figure 6 and Figure 9 As shown, the second telescopic sleeve 313 includes a second telescopic tube, a second telescopic rod, and a third oil supply pipe. The second telescopic rod is sleeved inside the second telescopic tube, and a second oil supply cavity is provided between the inner walls of the second telescopic rod and the second telescopic tube. The third oil supply pipe communicates with the second oil supply cavity. A third connecting rod is provided at the end of the second telescopic tube, and both ends of the third connecting rod are fixedly connected to the inner wall of the second outer tube 311. A fourth connecting rod is provided at the end of the second telescopic rod, and both ends of the fourth connecting rod are fixedly connected to the inner wall of the second inner tube 312.

[0028] In some embodiments of this application, such as Figure 3 , Figure 6 and Figure 9 As shown, a third oil supply connector is provided on the inner wall of the second outer tube 311, and a fourth oil supply connector is provided on the right telescopic outrigger 32. A fourth oil supply pipe 33 is also provided inside the second telescopic tube, with one end connected to the third oil supply connector and the other end connected to the fourth oil supply connector. This structure forms a hydraulic passage through the second oil supply chamber and the third oil supply pipe, providing power for the extension and retraction of the second telescopic sleeve 313. The third connecting rod and the fourth connecting rod respectively fix the second telescopic tube and the second telescopic rod to the second outer tube 311 and the second inner tube 312, allowing the hydraulic drive to be effectively converted into the lateral movement of the second inner tube 312, thereby controlling the extension and retraction of the right telescopic outrigger 32.

[0029] In some embodiments of this application, such as Figure 1 and Figure 2As shown, the drill rope 22 is sequentially connected to a traveling block 21, a sucker rod hook 23, and a sucker rod clamp 24 at its end, with the sucker rod clamp 24 connected to the sucker rod. With this structure, the drill rope 22 is connected to the sucker rod in series via the traveling block 21, sucker rod hook 23, and sucker rod clamp 24. The traveling block 21 bears the main load and guides the rope's direction, while the sucker rod hook 23 and sucker rod clamp 24 transmit the lifting force to the sucker rod in stages, forming a multi-stage connection. This makes the sucker rod tripping operation smoother and facilitates connection and disassembly during well workover operations.

[0030] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the main trailer 28 is also equipped with a dead-end fixing device 5, and the end of the drilling rope 22 is fixedly connected to the dead-end fixing device 5. With this structure, the end of the drilling rope 22 is firmly connected to the main trailer 28 through the dead-end fixing device 5, providing a stable fixing point for the drilling rope 22. This helps to maintain the tension stability of the drilling rope 22 during the winding and unwinding process of the winch 3, preventing the rope from loosening or slipping, thereby ensuring that the hoisting system composed of the traveling block 21, the sucker rod hook 23, and the sucker rod clamp 24 can operate smoothly during sand flushing and well workover operations.

[0031] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the main trailer 28 is also equipped with a driller's cabin 2. With this structure, the driller's cabin 2 is located on the main trailer 28, integrating the operation functions of the workover rig into one place. Operators can centrally control key components such as the winch 3 and hydraulic system from within the driller's cabin 2, and monitor the equipment's operating status. This facilitates coordination and management of workover operations and reduces the time spent by personnel traveling between different operating points during the operation.
