This application discloses a process for repairing casing in oil and water wells. The process includes obtaining the location and rate of diameter reduction within the casing, calculated from the deformed inner diameter and the initial inner diameter before deformation. When the rate of diameter reduction is less than or equal to a preset value, a reshaping process is used to repair the casing at the diameter reduction location. After reshaping, the repaired inner diameter is obtained. It is then determined whether the difference between the repaired inner diameter and the initial inner diameter is less than or equal to a first distance. When the difference is less than or equal to the first distance, an expansion tube process is used to repair the casing. Since the expansion tube process utilizes an expansion tube support, it can support the casing at the reshaping repair location, preventing further diameter reduction at that location and improving casing stability to ensure the repair meets the production requirements of the oil and water well.
