Title: A Coupling Device for Restraining and Regulating an Uncontrolled Gushing Out From an Oil or Gas Drilling
IPC: E21B33/02
Filed: 1980-02-21
Abstract: The coupling device is intended for closing a drilling pipe, from which oil or gas gushes out in an uncontrollable amount. A housing (1%) comprising a branch pipe (19) is carried downwards about the drilling pipe and fixed by means of tightening means such as hydraulic cylinders (7) comprising pistons pressing closure sections (4%) with claws against the wall of the drilling pipe. At the same time the closure sections are sealingly abutting each other edge to edge and thereby forming a pyramidal or conical closure. An increased pressure within the housing (1%) implies that the capability of the closure sections for holding the housing on the drilling pipe is increased. When a closing valve mounted in advance on the branch pipe (19) is closed the pressure transmitted to the top side of the closure sections (4%) is further increased. Through the pipe (19) the coupling device may be coupled to existing installations. <IMAGE>
