摘要： An improved repair connector for a subsea tubular member and the method of making such repair. The improved repair connector includes a annular housing and an annular guide, said annular housing having internal grooves filled with pressure compensating material, a concave recess having serrations therein, a rib having a downwardly facing shoulder on the interior of said housing, threads on the upper interior of said housing for receiving a string, and means carried by said guide for sealing against the exterior of a string on which the connector is to be installed. Also, a band of brittle material is positioned within a groove in the exterior of the housing which generates a noise upon the deformation of the housing responsive to completion of the forming of the tubular member therein. The method of connecting the improved connector includes the steps of preparing the casing at a level below the defect, lowering the improved connector into engagement with the upper end of the prepared casing within the well bore, exerting deforming pressure within the upper end of the casing to deform the casing into sealing engagement within the internal grooves in the connector, and releasing and recovering the means generating the deforming pressure.

摘要： A wellhead has, instead of a conventional Christmas tree, a spool tree (34) in which a tubing hanger (54) is landed at a predetermined angular orientation. As the tubing string can be pulled without disturbing the tree, many advantages follow, including access to the production casing hanger (21) for monitoring production casing annulus pressure, and the introduction of larger tools into the well hole without breaching the integrity of the well.

摘要： An improved method and apparatus for operating or setting equipment within a subsea marine wellhead from the surface having an indicating signal provided at the surface of the successful completion of such operation. The steps of the method include the lowering of a well component and the detecting and transmitting equipment on a running string from the surface; detecting the successful completion of the subsea operation, and transmitting to the surface of a signal signifying that the operations within the subsea well head have been successfully completed. The apparatus includes the running string, the detecting means which may be an acoustic detector or a ferrous metal detector or other suitable detector, a signal transmitter, means for supporting the detector and transmitter on the running string so that the well component can be properly lowered and positioned within the subsea wellhead and its proper landing, sealing or latching or other desired condition signalled to the surface to provide an indication that the operation has been completed.

摘要： An improved wellhead seal for sealing across the annular space between the exterior of a hanger and the interior of a wellhead housing having a seal ring with upper and lower rims, resilient metal lips on the interior of said lower rim for engaging the exterior of the hanger and gripping and sealing elements on the exterior of the upper rim and multiple camming surfaces on the interior of the upper rim and an actuating ring having multiple camming surfaces mating with the multiple camming surfaces on the upper rim so that downward movement of said actuating ring cams the gripping and sealing elements on said upper rim into tight metal-to-metal sealing engagement with the housing interior sealing surface. The sealing may be accomplished directly between the exterior of a hanger rim or by a seal ring positioned between the hanger rim and the interior housing surface.

摘要： The improved wellhead seal assembly includes an annular metal seal ring having upper spaced apart inner and outer rims with an upper energizing ring positioned between such rims and movable axially between them, a resilient seal embedded in and extending through ports in the central portion of the seal ring, lower inner and outer seal rings connected to said central portion of said seal ring by inner and outer bellows and a wedging ring depending from the central portion of the seal ring between such bellows and adapted to move downward between the inner and outer seal rings to wedge them apart into sealing engagement with the inner and outer sealing surfaces, such movement being responsive to downward movement of the upper energizing ring and the flexing of the lower bellows legs and continued movement of said upper energizing ring wedging said upper rims apart into sealing engagement with the inner and outer sealing surfaces, the upper energizing ring being releasably connected to the upper seal rims so that said upper seal is not set until the lower seal is completely energized and set.
