摘要： An underwater pipeline is disclosed that arrests the propagation of a collapse or buckle that may occur as the pipeline is being laid or after the pipeline is in service. The pipeline comprises a plurality of joints of pipe connected end-to-end by a threaded connection. Each connection includes external cylindrical threads of opposite hand on adjacent ends of the pipe joints. A coupling having right and left-hand threads for moving the ends of the pipe joints into abutting position in sealing engagement with a seal ring to seal the connection. The connection provides a physical discontinuity in the pipeline to stop the propagation of a buckle in the pipeline. Additionally, by virtue of the thread profile, the coupling may provide radial support to the pin members to resist collapse.

摘要： A system adapted for alternative use as a diverter or a blowout preventer for a bottom supported rig and adapted for positioning beneath a rotary table of the drilling rig is disclosed. The system comprises a fluid flow controller and at least two bases adapted for being alternatively removably secured to the controller. When the first base is in combination with the fluid flow controller, the system may be used only as a diverter and when the second base is used in combination with the fluid flow controller the system may be used only as a blowout preventer. A method according to the invention includes steps for installing the system adapted for alternative connection as a diverter or a blowout preventer for a bottom supported drilling rig after structural casing has been set in a borehole.

摘要： A seal member of elastomeric material is disclosed which is shaped to fit sealably within a recess of a flow diverter body. On the inside of the diverter body, a seal is effected against a slidable cylindrical valve sleeve. On the outside of the diverter body, a seal is effected against a permanent housing. The seal is constructed with an outer section having a generally circular opening, an inner section having an oblong opening and a connecting section between the outer and inner section having a bore therein connecting the circular opening with the oblong opening. A rigid support member embedded in the elastomeric material provides rigidity and strength to the seal member.

摘要： A marine riser safety valve is disclosed which, when placed in series with a deep water marine riser string, prevents collapse of riser pipe when inadvertent gas influx replaces the drilling fluid column. A cylindrical body is provided having a depression formed therein with at least one diaphragm port from the central bore of the body through the wall of the depression. A valve port is provided axially from the depression. A cylindrical member including a cylindrical diaphragm and a valve sleeve are joined end-to-end. The cylindrical member is disposed about the exterior of the body with the elastomeric diaphragm covering the depression and the valve sleeve covering the valve port. When a differential pressure develops across the wall of the diaphragm of a predetermined threshold, the diaphragm constricts into the body depression and moves the valve sleeve axially, opening the valve port to permit sea water influx. An outer skirt is provided to prevent outward ballooning of the diaphragm when bore pressure is greater than the surrounding sea water pressure.

摘要： An extended lift coupling for joining tubular members in an end-to-end relationship is disclosed. The coupling is of simple design having only three components: a pin, a box and a threaded lock ring. An external compressive axial preload places a torus on the pin in axial compression. Make-up of the lock ring maintains the compressive strain on the torus and the lock ring when the axial make-up force is removed. Thereafter, increased tensile loading on the pin and box is partially absorbed in benign compressive stress of the locking ring. By controlling the geometry of the coupling such that the stiffness of the torus is high compared to the stiffness of the box and the stiffness of the lock ring, the fatigue life of the coupling caused by applied cyclic tensile forces is enhanced.

摘要： FLOW DIVERTER Apparatus adapted for connection to a drilling conduit beneath a drilling rig floor for diverting pressurized well bore fluid in the conduit from the rig and sealing the annulus between a pipe or other object and the conduit or closing the vertical flow path of the conduit in the absence of any object in the conduit is disclosed. The apparatus includes a housing, an annular packing element and two pistons. The housing is provided with at least one outlet passage in the wall of its body, and one of the two pistons acts as a sliding sleeve valve in cooperation with the housing wall for preventing fluid communication between the outlet passage and the interior of the housing when it is in a nonactuated or normal position and for allowing fluid communication when it is in an actuated or diverting position. The second piston is advantageously disposed axially upwardly within the housing and is adapted for engagement with the upper part of the first piston after the first piston has moved an upward axial distance sufficient to insure opening of the outlet passage before the upward movement of the first piston urges the second piston upwardly thereby causing the annular packing element to close about an object in the housing bore. Another embodiment of the invention provides two outlet passages in the housing wall and two holes in the first piston. When the first piston is in the normal position, one of its holes is in alignment with one of the housing outlet passages, while the other outlet passage is covered by a portion of the piston wall. When actuated, the piston closes the previously opened outlet passage and opens the previously closed outlet passage.
