Abstract
Description
Technical Field

[0002] Wireline testing is a widely used testing method in oilfields. Its main components include a wireline, a pressure gauge, and a wire cap. The wireline is used to lower the pressure gauge to a designated location in the well, while the wire cap connects the wireline to other downhole tools, ensuring minimal or no rotation of the tool string during downhole rotation, thus preventing accidents caused by tool tripping.
[0003] A slickline well test system is a type of testing equipment used in oil exploration and production. Its main components include a winch, pulley system, slickline, pressure gauge, and thermometer. The winch provides power, driving the downhole tool through the slickline to perform various testing operations. The pulley system changes the direction of the slickline to ensure smooth testing. The slickline acts as a bridge between surface equipment and downhole tools, bearing both tension and pressure.
[0004] In the existing technology, during the steel wire well testing process, the steel wire needs to withstand stresses such as tension and bending moment, as well as the corrosive effect of downhole fluids. Excessive tension will cause the steel wire to withstand stress beyond its bearing capacity, thereby increasing the risk of breakage. Once the steel wire breaks, it will not only cause the well testing operation to fail, but also pose a serious safety threat to downhole equipment and personnel. Therefore, a steel wire well testing stable tension adjustment device structure is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 2The utility model provides an embodiment: a structure of a wireline well testing stabilization tension adjustment device, comprising a base 1 and a wire rope 3, wherein the base 1 is made of high-strength steel to ensure its stability and durability. A fixed column 4 is fixedly connected to the top of the base 1, and two rotating rods 5 are rotatably connected to the outside of the fixed column 4. The adjacent sides of the two rotating rods 5 are rotatably connected to a movable pulley 11, and the position change of the rotating rod 5 drives the position of the movable pulley 11 to move. One end of the wire rope 3 is sleeved on the outside of the movable pulley 11. The position change of the movable pulley 11 changes the traction force of the wire rope 3. In order to reduce friction and improve transmission efficiency, the movable pulley 11 is made of wear-resistant material.
[0033] The inner wall of the base 1 is mounted with a motor 7, the driving end of which is fixedly connected to a disc 8. The disc 8 is made of a lightweight alloy material to reduce the overall weight and improve the rotation efficiency. When the motor 7 is started, the position change of the driving end of the motor 7 drives the disc 8 to rotate. The outer rotation of the disc 8 is connected to a connecting rod 9 (see attached). Figure 2 ), the rotation of disk 8 drives connecting rod 9 to rotate about the center of disk 8. A movable rod 10 is movably connected to the inner wall of connecting rod 9. Changes in the position of connecting rod 9 cause changes in the position of movable rod 10. The other end of movable rod 10 is rotatably connected to the exterior of rotating rod 5. Changes in the position of movable rod 10 cause changes in the position of rotating rod 5.
[0034] Reference Figure 1 The top of the base 1 is fixedly connected to an auxiliary component that assists in wireline well testing. The auxiliary component includes a winch 2. The bottom of the winch 2 is mounted on the top of the base 1. One end of the wire rope 3 is installed inside the winch 2. The winch 2 has the function of fixing one end of the fixed pulley 12. The top of the fixed column 4 is fixedly connected to the fixed pulley 12. The outer part of the wire rope 3 is slidably connected to the outside of the fixed pulley 12. The fixed pulley 12 has the function of supporting the wire rope 3. The fixed pulley 12 is made of high-strength bearing material to ensure that it can still work smoothly under high loads.
[0035] Reference Figure 1 、 Figure 3 and Figure 4 The top of the base 1 is fixedly connected to a fixed platform 13, and the top of the fixed platform 13 is fixedly connected to a plurality of telescopic columns 6. The inner wall of the fixed platform 13 is slidably connected to a sliding plate 15. The bottom of the sliding plate 15 is fixedly connected to the top of the plurality of telescopic columns 6. The sliding plate 15 drives the telescopic changes of the plurality of telescopic columns 6, thereby keeping the sliding plate 15 stable during the movement. The inner wall of the sliding plate 15 is fixedly connected to a plurality of springs 17 (as shown in the attached figure). Figure 4), the other ends of the multiple springs 17 are fixedly connected to the cleaning plate 16. The cleaning plate 16 moves in the opposite direction, causing the springs 17 to deform. The return of the multiple springs 17 drives the cleaning plate 16 to continue to approach the wire rope 3. The bottom of the cleaning plate 16 contacts the outside of the wire rope 3. The position change of the sliding plate 15 drives the cleaning plate 16 closer to the wire rope 3, thereby cleaning the outside of the wire rope 3 as the position of the wire rope 3 changes.
[0036] The fixed platform 13 is externally mounted with a second motor 14. The driving end of the second motor 14 is fixedly connected to a rotating rod 19. When the second motor 14 is started, the rotation of the driving end of the second motor 14 drives the rotating rod 19 to rotate. The external portion of the rotating rod 19 is rotatably connected to the inner wall of the fixed platform 13. The inner wall of the sliding plate 15 is rotatably connected to a fixed rod 18 (see attached). Figure 3 ), the position change of the fixed rod 18 drives the position change of the sliding plate 15. Both ends of the fixed rod 18 are fixedly connected to the traction line 20 (as shown in the attached Figure 3 ), the other ends of the two traction lines 20 are fixedly connected to the outside of the rotating rod 19, and the rotation of the rotating rod 19 drives the traction lines 20 to reel in, so that the other ends of the traction lines 20 can pull the position of the fixed rod 18 to change.
[0037] Working principle: Start motor 7. The rotation of the driving end of motor 7 drives disc 8 to rotate. The rotation of disc 8 drives one end of connecting rod 9 to rotate around the center of disc 8. The rotation of connecting rod 9 drives movable rod 10 to slide on its inner wall, so that the position change of movable rod 10 drives the position of rotating rod 5 to change in an arc shape, thereby driving the position change of fixed pulley 12, so that the traction force on wire rope 3 changes, thereby changing the wire tension. By controlling the tension of the wire, the stability and safety of the test process can be ensured, and accidents such as wire breakage and seal failure caused by excessive or insufficient tension can be avoided. At the same time, reasonable tension adjustment can also reduce the wear between the wire and the sealing packing, extending the service life of the equipment.
[0038] Start the motor 2 14. The rotation of the driving end of the motor 2 14 drives the rotating rod 19 to rotate. The rotation of the rotating rod 19 drives the traction wire 20 to reel in, so that the other end of the traction wire 20 can pull the position of the fixed rod 18 to change, so that the sliding plate 15 can slide down on the inner wall of the fixed platform 13, and the sliding plate 15 drives the telescopic changes of the multiple telescopic columns 6, so that the sliding plate 15 is kept stable during the movement. The position change of the sliding plate 15 drives the cleaning plate 16 to approach the wire rope 3, so that the outside of the wire rope 3 is cleaned as the position of the wire rope 3 changes. Cleaning the steel wire can effectively remove dirt, grease and corrosion products on the surface, reduce the risk of wear and breakage, and improve the strength and durability of the steel wire. In addition, the surface of the cleaned steel wire is smoother, which helps to reduce friction with other equipment and improve the efficiency and safety of well testing operations.
