Abstract (en)

[origin: WO9827312A1] System for controlling oil well fires by blocking the production or drilling pipes. A box incorporating a movable piston is fitted around the pipe. The piston carries, on its forward end, a drilling cylinder (3), which can be brought to the pipe by a hydraulic piston-cylinder arrangement. Subsequently, the drilling cylinder drills through the pipe wall and after that the drilling cylinder or a separate plugging cylinder (4) is left in the drilled hole and blocks the fluid flow through the pipe. The process is remote controlled.
