The application provides a drilling leak stoppage valve. The drilling leak stoppage valve comprises a leak stoppage valve body, an elastic member, a sliding sleeve, a ball seat and a ball catcher. The leak stoppage valve body comprises a first cavity, an inner step and a first opening on the side wall of the body. The bottom end of the elastic member abuts against the inner step. The sliding sleeve is slidably arranged in the first cavity and the bottom end is supported by the elastic member. The sliding sleeve comprises a second cavity and a second opening on the side wall thereof, and the second opening can be moved to a position in alignment with the first opening when the elastic member is compressed. The ball seat is arranged in the second cavity and is positioned between the second opening and the bottom end of the sliding sleeve, the ball seat is connected to the inner wall of the sliding sleeve and has a ball seat opening for accommodating a ball, and the ball seat can be deformed at a predetermined pressure to increase the radial size of the ball seat opening. The ball catcher is connected to the bottom end of the leak stoppage valve body. The drilling leak stoppage valve is more stable in performance and is not affected by the high temperature and high pressure at the bottom of the well, and is convenient for plugging the well leakage under the high temperature and high pressure environment.
