Description

Technical Field

[0001] The present invention belongs to the technical field of casing repair, and particularly relates to a hydraulic casing shaping and repair device based on oscillating impact. Background Art

[0002] During the oilfield exploitation process, due to factors such as in-situ stress, the downhole casing will undergo deformation and other damage conditions. The occurrence of such a situation will lead to a continuous decrease in the number of production wells in the oil well, and even the situation of production suspension may occur. In response to this situation, a hydraulic casing shaping and repair device is usually required to repair it.

[0003] The document with the publication number CN113622855A discloses a casing hydraulic shaping device, including a pressure relief switch structure, an anchor structure, a hydraulic push cylinder structure, and a shaping device structure; the anchor structure is arranged at the bottom end of the pressure relief switch structure; the upper end of the pressure relief switch is connected to a tubing or a drill pipe and is lowered all the way to the casing necking position. Water is injected and pressurized on the ground. The hydraulic push cylinder converts the hydraulic pressure on the ground into an axial mechanical thrust, and then the hydraulic push cylinder pushes the roller-type shaper to move downward. The roller-type shaper converts the thrust into a radial expansion force, and the rollers at its head perform a rolling motion to extrude the casing at the necking position outward, causing the casing to plastically deform outward and recover. Using hydraulic pressure as the power source, a huge shaping force is generated; it can quickly repair one or more continuous casing deformation sections. One string of pipe can basically complete the workover operation, reducing the operation procedures and improving the speed of repairing the casing. However, in the actual repair operation process, a single outward expansion repair is difficult to eliminate the local stress concentration phenomenon, which easily affects the repair effect of the hydraulic casing. Therefore, improvements are needed. Summary of the Invention

The repair cylinder performs an outward expansion repair on the deformed part by moving outwards. At the same time, the fixed rack cooperates with the transmission gear, the rotating cam, the second spring and the connecting rod to drive the vibrating block to perform high-frequency vibration on the repair cylinder. Driven by the transmission rod, the mechanical outward expansion structure formed by the linkage of the extrusion block and the moving box can apply a continuous and stable expansion force to the deformed part of the hydraulic casing. Cooperating with the high-frequency mechanical vibration wave generated synchronously during the outward movement of the repair cylinder, it can effectively decompose the residual stress on the inner wall of the casing, thereby significantly improving the uniformity and efficiency of the deformation repair. At the same time, through the mechanical linkage design, the synchronization control of vibration and expansion is realized, ensuring the continuity of the force distribution during the repair process and avoiding the risk of secondary deformation. Moreover, through high-frequency vibration, the local stress concentration phenomenon that may be generated by traditional rigid expansion is eliminated, improving the repair effect and repair efficiency.

[0016] 2. In the present invention, by providing an oscillation assembly, the fixed plate drives the oscillation ring to reciprocate in the vertical direction through the push block, push wheel, third spring, sliding column, hinge seat and connecting rod. The oscillation of the oscillation ring in the vertical direction drives the outer housing to vibrate. Through the generated vibration force, the traveling power of the outer housing in the hydraulic casing can be effectively improved, and the traveling efficiency of the outer housing entering the deep hydraulic casing can be improved. At the same time, during the repair process of the hydraulic casing, the vibration force generated by the longitudinal vibration of the outer housing itself can assist in improving the repair speed of the inner wall of the hydraulic casing, thereby improving the repair efficiency.

[0017] 3. In the present invention, by providing a pressurization assembly, the hydraulic oil squeezes the load spring and nitrogen gas through pressurization, enabling the piston body to have potential energy. When the pressure relief component relieves pressure, the compressed nitrogen gas and load spring release the potential energy pressure and drive the piston body to move downward, and transmit the impact force to the transmission rod. By converting the hydraulic force into a kind of potential energy and allowing the potential energy to do work under specific conditions, an impact force is generated instantaneously. Kinetic energy transmission can be achieved without too high pressure, avoiding the long-term existence of high-pressure states and reducing potential safety hazards.

[0023] The implementation method is specifically as follows: By setting the repair component 6, the extrusion block 602 drives the repair cylinder 601 to move outward through the extrusion wheel 609, the moving rod 607 and the moving box 605. The repair cylinder 601 performs an outward expansion repair on the deformed part by moving outward.

Driven by the transmission rod 8, the mechanical outward expansion structure formed by the linkage of the extrusion block 602 and the moving box 605 can apply a continuous and stable expansion force to the deformed part of the hydraulic casing. Cooperating with the high-frequency mechanical vibration wave generated synchronously during the outward movement of the repair cylinder 601, it can effectively decompose the residual stress on the inner wall of the casing, thereby significantly improving the uniformity and efficiency of the deformation repair. At the same time, through the mechanical linkage design, the synchronization control of vibration and expansion is realized, ensuring the continuity of the force distribution during the repair process and avoiding the risk of secondary deformation. Moreover, through high-frequency vibration, the local stress concentration phenomenon that may be generated by traditional rigid expansion is eliminated, improving the repair effect and repair efficiency.

A connecting rod 703 is hinged to the periphery of the bottom of the oscillation ring 701. The other end of the connecting rod 703 is hinged to a hinge seat 704. A sliding column 705 capable of reciprocating motion is connected to the bottom of the hinge seat 704. The other end of the sliding column 705 is connected to a pushing wheel 711. Connecting frames 706 are connected to the periphery of the inner wall of the outer casing 5. The cross-sectional shape of the connecting frame 706 is L-shaped. The sliding column 705 is slidably connected to the connecting frame 706. A third spring 710 is sleeved on the outer surface of the sliding column 705. The two ends of the third spring 710 are respectively connected to one side of the connecting frame 706 and one side of the pushing wheel 711. A plurality of weight columns 702 distributed in an array are connected to the outer peripheral side of the oscillation ring 701. A plurality of sliding grooves distributed in a circumferential array are opened at the top of the oscillation ring 701. A fixed sliding rod 709 is slidably connected in the sliding groove. The other end of the fixed sliding rod 709 is connected to the inner wall of the outer casing 5. A fixing plate 707 is connected to the outer peripheral side of the transmission rod 8. A pushing block 708 distributed in a linear array is connected to one side of the fixing plate 707. The pushing block 708 and the fixing plate 707 periodically fit with the pushing wheel 711.

[0025] The implementation method is specifically as follows: By setting the oscillation component 7, the fixed plate 707 drives the oscillation ring 701 to reciprocate in the vertical direction through the push block 708, the push wheel 711, the third spring 710, the sliding column 705, the hinge seat 704 and the connecting rod 703. The vibration of the oscillation ring 701 in the vertical direction drives the outer casing 5 to vibrate. Through the generated vibration force, the traveling power of the outer casing 5 in the hydraulic casing can be effectively improved, and the traveling efficiency of the outer casing 5 entering the deep hydraulic casing can be improved. At the same time, during the repair process of the hydraulic casing, the vibration force generated by the longitudinal vibration of the outer casing 5 itself can assist in improving the repair speed of the inner wall of the hydraulic casing, thereby improving the repair efficiency.

[0026] The pressurizing component 3 includes an inner tube 304, and the inner tube 304 is connected inside the outer sleeve 2. A flow cavity is formed between the outer sleeve 2 and the inner tube 304, and hydraulic oil flows in the flow cavity. A partition 308 is connected inside the inner tube 304 from top to bottom. A sliding rod 305 is slidably connected between the two partitions 308. The top of the sliding rod 305 extends to the other side of the partition 308 and is connected with a piston body 302. An annular block 307 is connected to the outer surface of the sliding rod 305. A load spring 306 is sleeved on the outer surface of the sliding rod 305. Both ends of the load spring 306 are respectively connected with one side of the annular block 307 and one side of the partition 308. A plurality of inlet and outlet ports 303 are opened on the outer peripheral side of the inner tube 304, and a plurality of pressure relief members 301 are communicated with the outer peripheral side of the outer sleeve 2.

[0027] The implementation method is specifically as follows: By setting the pressurizing component 3, the hydraulic oil pressurizes and squeezes the load spring 306 and nitrogen gas, so that the piston body 302 has potential energy. When the pressure relief member 301 relieves pressure, the compressed nitrogen gas and the load spring 306 release the potential energy pressure and drive the piston body 302 to move downward, and transmit the impact force to the transmission rod 8. By converting the hydraulic force into a kind of potential energy, and the potential energy does work under specific conditions, an impact force is generated instantaneously, and kinetic energy transmission can be realized without too high pressure, avoiding the long-term existence of the high-pressure state and reducing potential safety hazards.

[0028] Working principle: When in use, the staff inserts the whole device into the hydraulic casing. Then, the staff transports hydraulic oil into the outer sleeve 2 through an external device and the connecting member 1. Nitrogen gas is stored between the piston body 302 and the top of the inner tube 304. The hydraulic oil enters the inlet and outlet ports 303 through the flow cavity, and pressurizes and squeezes the load spring 306 and nitrogen gas in the inner tube 304, so that the piston body 302 moves upward and has potential energy. Then, the pressure relief member 301 relieves pressure, and the compressed nitrogen gas and the load spring 306 release the potential energy pressure and drive the piston body 302 to move downward, and transmit the impact force to the transmission rod 8.

[0029] When repairing the hydraulic casing, the transmission rod 8 gradually moves downward under the drive of the pressurizing assembly 3. The transmission rod 8 drives the fixed plate 707 to move downward, the fixed plate 707 drives the push block 708 to move downward, the push block 708 drives the push wheel 711 to move to one side, and the third spring 710 drives the push wheel 711 to move in a reset manner, so that the push wheel 711 makes a reset movement. The push wheel 711 drives the sliding column 705 to make a reciprocating movement, the sliding column 705 drives the hinge seat 704 to make a reciprocating movement, the hinge seat 704 drives the connecting rod 703 to reciprocate, and multiple connecting rods 703 drive the oscillation ring 701 to reciprocate in the vertical direction. The oscillation of the oscillation ring 701 in the vertical direction drives the outer casing 5 to vibrate, assisting in the repair of the hydraulic casing.

[0030] When repairing the deformation of the hydraulic casing, the transmission rod 8 drives the extrusion block 602 to move downward. The extrusion block 602 drives the surrounding extrusion wheels 609 to move to one side. The extrusion wheels 609 drive the moving box 605 to move to one side through the moving rod 607. The moving box 605 drives the repair cylinder 601 to move outward. The repair cylinder 601 performs an outward expansion repair on the deformed part through outward movement, so that the hydraulic casing returns to its original state. During this process, the moving box 605 drives the transmission gear 603 to move on the fixed rack 604, so that the transmission gear 603 rotates on its own. The transmission gear 603 drives the rotating cam 610 to rotate. The rotating cam 610 drives the moving plate 611 to move, and the second spring 612 drives the moving plate 611 to make a reset movement, so that the moving plate 611 makes a reciprocating movement. The moving plate 611 drives the connecting rod 614 to make a reciprocating movement. The connecting rod 614 drives the vibration block 613 to perform high-frequency vibration on the repair cylinder 601, cooperating with the outward expansion of the repair cylinder 601 itself to assist in improving the repair speed of the hydraulic casing.
