发明名称 PRESSURE RELEASE ASSEMBLY FOR CASING OF DRILLING RIG
摘要 An apparatus is for a drill rig platform configured to be operative with a casing system having a check valve fixedly positioned in a casing joint. The apparatus includes a casing pressure relief assembly fixedly positionable relative to the check valve positioned in the casing system. The casing pressure relief assembly is configured to actuate the check valve in such a way that the check valve actuatably releases internal pressure from the casing system. In this manner, the internal fluid pressure of the pressurized fluid trapped in the casing system is released once the casing pressure relief assembly actuates the check valve.
