The invention discloses a thread-based under-pressure oil pipe leakage repairing device, and relates to the technical field of pressure pipeline protection devices. The thread-based under-pressure oil pipe leakage repairing device comprises a compression bolt, a lock washer, an end cover, a rotating hand wheel, a main rotating rod, a rear pressing plate bolt, a rear pressing plate, a cavity, a push sleeve, a leakage-proof partition plate sleeve, a transmission gear shaft, a push cover, a front pressing plate, a control gear shaft, a flange buckle, a rubber hole film and the like. When leakage repairing is carried out, a leakage repairing flange and the rubber hole film wrap a leakage point, the rotating hand wheel is rotated, a main transmission rod drives the push sleeve to push a leakage repairing agent in the cavity forwards, the leakage repairing agent is evenly distributed in the rubber hole film, the leakage repairing agent overflows from small holes of the rubber hole film and is in full contact with the leakage point, and then an injection needle on the rubber hole film is pulled out to complete leakage repairing; and emergency leakage repairing can be conducted on the oil pipe under the condition of medium-low pressure pipeline leakage, and the device has the characteristics of being wide in applicability, high in leakage repairing efficiency, easy to operate and the like.
