摘要： The improved structure of the present invention includes a hanger (10) having a landing seat (16) for engaging the landing seat (18) within a wellhead housing (14), a hanger holddown ring (24), an external sealing surface spaced from the internal sealing surface of the housing to form the annulus to be sealed, a seal assembly (12) including a seal body (100) having external metal seal legs (102, 104) diverging outward but having a free diameter less than the diameter of the housing internal sealing surface and internal metal seal legs (106, 108) converging inwardly and having a free diameter smaller than the diameter of the hanger external sealing surface, a lower body (110) movably connected to the seal body and having an upstanding rim (118) engaging the lower outer seal leg, an upper body (112) movably connected to the seal body, a loading ring (136) surrounding the upper portion of the seal body and engaging the upper outer seal leg, means (153) for securing said seal assembly to said hanger after said seal assembly has been set in loaded sealed position and means for retaining said loading ring against the upper outer seal leg to latch said seal assembly in loaded sealed position. In a modified form the seal body includes an upper outer seal leg extending upwardly and outward and having a free diameter less than the internal sealing diameter of the housing and a lower outer seal leg extending upwardly and having a free diameter larger than the internal sealing diameter of the housing and this form does not have a lower body or upper rim supporting the lower outer seal leg. It does have the means for loading the upper outer seal leg and the latch to retain the seal assembly in sealing position.

摘要： A method and apparatus for the protection of downhole equipment from excessive pressure conditions which includes providing structures of volume compensating material which are designed to resist normal pressures expected in the well bore. One form of the invention has a plurality of half sections (26) of volume compensating material positioned around one of the tubular members (22) in the annulus (20) which has fluids that can increase in pressure to a point approaching damage to the inerior or exterior member of the annulus. In another application a resilient seal includes a recess into which a ring of volume compensating material is placed to allow a place for fluids to flow when they are subjected to overpressure conditions.

摘要： A ratcheting connector 10 for providing a radial connection between two concentric tubular members 12, 16, with one of the members 12 having a recess in which a split latching ring 14 is mounted with coarse threaded engagement between the split latching ring and the one member and fine threads 28 on the side of said split latching ring facing the other member 16 which has mating fine threads 30 with a shape which cams the split latching ring into its recess as the threads move past each other in the direction of installation. Setting of the connector is accomplished after full engagement of the fine threads by rotation of the central tubular member 12 less than a full revolution.
