Aiming at the problems that the shaping force of the shaping tool on the sleeve is smaller, the tool abrasion is larger and the like in the prior art, the application provides a hydraulic control synchronous telescopic torque-changing type oil-gas well sleeve shaping tool, wherein a power output mechanism converts part of kinetic energy of fluid in a well into torque and outputs the torque to a torque increasing mechanism, the torque increasing mechanism is used for increasing the torque as the name implies and outputs the increased torque to a repairing mechanism, and the repairing mechanism receives power transmitted by the torque increasing mechanism and enables an extrapolation block to move along the radial direction of the tool so as to apply radial outward acting force to the deformed sleeve of the well wall, thereby realizing shaping and repairing of the deformed sleeve.
When the application works, the tool is sent into the well until the tool reaches the deformation section of the casing, and drilling fluid, completion fluid and other fluids are pumped into the well.
It can be seen that the application is realized by means of the hydraulic force of the drilling fluid or the completion fluid pumped into the well, and the like, the deformed casing is forced and extruded in the working process, and the torque increasing mechanism is used for increasing the output torque, so that the radial outward thrust of the push block is increased, and compared with the prior art, the application can provide larger repairing force for the casing, thus the shaping capability is obviously improved; in addition, when the tool is used, the tool does not need to make axial or circumferential movement wholly, the shaping block repairs the sleeve in a radial extrusion mode, the technical thought of repairing the deformed sleeve in the mode of wholly axially moving the shaping block in the prior art is abandoned, the abrasion of the shaping tool and the sleeve is remarkably reduced, and the service life of the tool is prolonged; in addition, the application can continuously repair the casing with more deformation points and longer deformation sections, can complete large-section repair operation by one-time well logging without repeated tripping operation, and obviously improves the casing repair efficiency of the oil and gas well; finally, the application can meet the casing repair operation of different well diameters by matching with the extrapolation blocks with different sizes, has larger use flexibility and improves the application range of the casing repair tool.
It should be noted that, the power output mechanism in the present application may adopt any structure capable of outputting torque by using kinetic energy of fluid in the well in the prior art, such as a hydraulic motor, a screw drilling tool, a propeller blade, etc.; the torque increasing mechanism can adopt any structure capable of increasing output torque in the prior art, such as a turbo-charging structure, a torque increasing motor structure, a speed changer structure and the like; the repairing mechanism can adopt any structure capable of converting rotation into radial motion in the prior art, such as a reversing gear set, a chuck, cam transmission and the like.

In the scheme, the power output mechanism is driven by fluid in a moving state in the well, part of kinetic energy of the fluid is converted into rotating torque of the power output shaft, the rotating torque is output outwards through the torque output shaft after being increased by the torque increasing mechanism, and finally the repairing mechanism is driven to act through the torque output shaft. It can be seen that the torque transmission among the power output mechanism, the torque increasing mechanism and the repairing mechanism is realized through the power output shaft and the torque output shaft, so that the transmission difficulty is reduced, and the transmission structure is simplified.
