摘要： This invention provides a method and apparatus for maintaining safe pressure in the annulus of a deepwater marine riser by preventing the displacement of drilling mud with formation gas. By providing an improved flow diverting control device having an annular sealing device in the riser string below the riser telescopic joint, liquid well fluids under limited pressure can be maintained in the riser despite the impetus of formation gas below the mud column to displace the liquid. Provision of the annular shut-off below the telescopic joint eliminates the necessity to seal well fluid pressure at the telescopic joint packer during kick control circulating operations. The flow diverting control device includes an outlet which opens on the closing of the annular sealing device and which provides a flow path beneath the annular sealing device to a choke line to facilitate bringing the well under control by circulating kill mud. If the BOP stack is on bottom, circulation can be directed down a riser kill line and introduced into the annulus above a closed ram. If the BOP's are open or if the stack is not on bottom, circulation is directed down the drill pipe, up the riser annulus and through the choke manifold. By maintaining a mud column in the riser annulus, the hazard of collapsing the pipe by external hydrostatic head near the lower end of a deepwater marine riser is avoided.

摘要： Apparatus is disclosed which is 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. The apparatus includes a housing, an annular packing element and two annular pistons. The housing is provided with two outlet passages in its wall. A first piston covers one outlet passage in the housing wall for preventing fluid communication between that outlet passage and the interior of the housing when it is in a nonactivated position and for aligning a first hole in the piston wall with the outlet passage for allowing fluid communication when the piston is in an activated position. The piston also serves to allow fluid communication between the second outlet wall passage and the interior of the housing via a second hole in the piston wall when the piston is in the normal position and to prevent fluid communication therebetween when the piston is in an activated position. Sequencing means are provided to insure that the second piston in the housing is moved axially upwardly sufficiently to urge the annular packing inwardly into sealing engagement with a pipe or other object in the bore only after the first piston closes the second outlet wall passage and opens the first passage. Permanently mounted support members are provided below the rig support structure of the rotary table into which the diverter is inserted. Cooperative alignment means are provided in the diverter and the support member in order that the outlet passages of the diverter may automatically mate with permanently mounted vent and flow lines. A seal member in the housing wall seals about the housing outlet to the first piston on the inside of the housing wall and to the permanent support member on the outside of the housing wall.

摘要： To arrest the propagation of a collapse or buckle the pipeline comprises a plurality of joints of pipe connected end-to-end by threaded connections. Each connection includes external cylindrical threads 14, 16 of opposite hand on adjacent ends of the pipe joints 10, 12 and a coupling 18 having complementary threads 20, 22 for moving the ends of the pipe joints into abutting position in sealing engagement with a seal ring 32 to seal the connection. Each connection provides a physical discontinuity in the pipeline to stop the propagation of a buckle. The thread profile may be dovetailed or hooked provide radial support to the pipe members to resist collapse.
