The invention discloses a shaping repair technological method of a casing deformation well, and belongs to the technical field of well repair of oil-water wells in the petroleum extraction. Firstly, a perforation technology is adopted to perforate a deformed part of a casing to release the external stress borne by the deformed well section casing; then, a mechanical shaping method is adopted to perform the percussion drilling pressure shaping for the deformed well section; a reinforcing agent is injected to reinforce the casing deformation well section; and finally, the well wall is rebuilt by a drilling and milling method. The shaping repair technological method of the casing deformation well is different from the conventional casing shaping reinforcement, and rebuilds a high-strength manual shaft on the outer wall of the casing by a mode of adding liquid curing resins between the outer wall of the casing and the stratum, so that the service life of the casing is prolonged.
