Abstract
An intelligent impact casing shaping tool in the field of deformation casing shaping and repair is disclosed. It includes a power module, a detection module, and a repair module. The power module generates power through rotation of a turbine, while the detection module sends pipe wall information to a ground receiving device in real-time. When pipe wall defects are detected, repair operations can be done by increasing the flow rate of the drilling fluid. As the flow rate increases, a clutch unit in the repair module engages with a power disk by centrifugal force of a centrifugal block, transmitting power to a cam seat. When the cam seat rotates, the cam engages with a roller, lifting an impact hammer. As the roller descends, an impact spring releases energy, and a repair push block strikes the deformed area, repairing the deformed casing.
