物理教师摘要：An inflatable well bore packer element, having inner and outer elastomer plies and an intermediate sheath of reinforcing wires, is cured at each end to a central mandrel by inner and outer annular coupling members. Wedge-shaped gripping members that hold the free ends of the reinforcing wires between facing surfaces of the coupling members are positioned and cured by independently tightened rings. The inner elastomer ply is bonded to the inside of the inner coupling member, and the tip of the inner coupling member is formed with a deformable skirt portion that flexes during packer inflation to oppo extrusion of the inner ply into the reinforcing wire holding area between the facing surfaces. The tip of the outer coupling member is rounded to protect the outer elastomer ply from tearing.
