摘要：The shear ram assembly for shearing an oil well tubular T includes a first ramaxially moveable along the first axis for moving an upper blade and an opposing secondram axially moveable along the second ram axis for moving a lower blade An upper
planar surface of the lower blade passes closely adjacent a lower planar surface of theupper blade as the blades move towards each other to shear the tubular. The sealingsystem is positioned within a recess in the upper surface of the lower blade, and includesan elastomeric seal for sealing engagement with the lower planar surface of the upperblade and a rigid actuator moveable relative to the lower blade to energize theelastomeric seal.
