ABSTRACT:
An improved stripper rubber for a rotating blowout preventor. The stripper rubber has an upper annular area attached to the lower end of a metal support member. The support member extends upwardly into fixed relationship respective to part of the rotating head of a rotating blowout preventor. The stripper rubber downwardly depends into concentrically arranged, spaced annular body members. The inner annular body has an axial passageway formed therethrough for telescopingly receiving a rotating member in sealed relationship therewith. The outer annular member has an outer circumferentially extending wall surface which rotatably engages the lower marginal end of a washpipe. The inner and outer annular members are made integral respective to the stripper rubber, and are separated from one another by a downwardly opening annular recess. The annular recess is formed by a number of walls arranged to deflect debris flowing uphole, such that the debris impact against the wall surfaces and is deflected through the lateral outlet passageway of the rotating blowout preventor rather than impacting against any vital components thereof.
