Processing and Understanding of the Pipe-stuck Accidents in Kongqueting B2H Well
Ground collapse caused the pipe-stuck accidents in φ212.725 mm hole of KQT-B2H. In this accidents, limited actived drill pipe, added torque, depressed, pulled drill pipe with pressure, hammer tool and so on, were used, but failed. Combined with the pipe, casing and ground, succed unfreezing through add pressure to annular. It widen the pipe-stuck treatment method and accumulated experience.
