High-energy quantitative cannula reshaping device, system, and method

Abstract

The application discloses a high-energy quantitative casing shaping device, system and method. The device comprises, from top to bottom, a running assembly, an igniting assembly, an anchoring assembly and a shaping assembly connected in sequence. The running assembly is used for inputting liquid into the sleeve through an external oil pipe to push the ball seat downward to impact a detonator to ignite the shaping explosive. The anchoring assembly is used for pushing the piston downward to drive the shaping main body to impact the deformation of the casing inner wall when the shaping explosive is ignited. The system comprises a controller, an electrically-controlled valve, an oil pipe, an oil pipe hanger, a lifting device, a weight indicator and the device. The method comprises the following steps: controlling the lifting device to lower the device into the casing through the oil pipe; monitoring the weight change measured by the weight indicator; and determining whether the device is lowered to the deformation of the casing based on the change to shape the casing. The device, system and method can reliably shape and repair the casing, and effectively avoid the problems of incomplete repair and over-repair.
