摘要： A tool for use in a subterranean well to seal with a generally cylindrical interior surface of a tubular or another downhole tool, the tool comprising:
a conveyance tubular for positioning the tool at a selected location below the surface of the well;
an annular seal assembly disposed about the conveyance tubular, the seal assembly having a reduced diameter run-in position and an expanded sealing position;
a wedge ring having a substantially conical outer surface configured to radially expand the annual seal assembly upon axial movement of the annular seal assembly relative to the wedge ring such that the seal assembly is expanded from its run-in position to its expanded sealing position wherein the seal assembly is in sealing engagement with the generally cylindrical interior surface; and
the annular seal assembly including a metal framework having a radially inward annular base and a plurality of metal ribs each extending radially outward from the base, the metal framework including an upper downwardly angled primary seal metal rib for sealing pressure below the seal assembly, a lower upwardly angled primary seal metal rib for sealing pressure above the seal assembly, a primary elastomeric seal in a cavity readially outward from the base and axially between the upper primary seal metal rib and the lower primary seal metal rib, an upper downwardly angled secondary seal metal rib spaced axially above the upper primary seal metal rib, and a lower upwardly angled secondary seal metal rib spaced axially below the lower primary seal metal rib.

摘要： A downhole tool (100) includes a closure seat (116, 176) for seating with a closure, such as a, ball. Shear pins or other connectors temporarily limit axia movement of the closure seat which is initially housed within a restricte diameter portion of the central throughbore in the tool body. The closure sea may be lowered to engage a stop (108, 157), thereby positioning the seat withi an enlarged diameter bore portion of the tool and allowing radial expansion of closure seat to release the ball.

摘要： Method and apparatus are disclosed to complete a threaded connection between two connector members by relative rotation between the connectors, utilizing fluid pressure between them to overcome radial load resistance during make up by rotation, and thereafter to produce axial and radial loading in the completed connection, but without otherwise applying longitudinal forces to drive the two connectors together to make up the threaded connection. In a disclosed embodiment, a pin connector (10) has a tapered neck with external threads, and a box connector (12) has a collar with a tapered interior, featuring tapered threads. The pin neck is received within the box collar, and the two sets of threads are made up by relative rotation between the pin and box. When a stall position is reached due to radial resistance forces, two combinations of bump and ramp seals (38,42,48,52) provide a sealed zone between the sets of threads. Fluid pressure is applied in the sealed zone to radially contract the neck and expand the collar without breaking the sealing engagement between the bump seals and the ramp seals. The resulting reduction of radial resistance between the neck and collar allows the further threading of the pin and box together by rotation between them until load surfaces of the pin and box mutually engage. Subsequent release of the fluid pressure from the sealed zone allows the pin neck to expand and the box collar to contract, moving the two sets of threads together, and radially loading the engagement at the seals. The load surfaces of the pin and box threads are slanted so that a wedging action is produced that further axially loads the connected pin and box.

摘要： A liner hanger running tool (10) and method are provided for positioning a liner in a well bore. A tool mandrel (24) is supported from a running string, and a housing (44) surrounds the tool mandrel. A flow annulus between the mandrel and the housing allows fluid to pass upward through the running tool to a position above the liner. A hydraulic release mechanism (78, 79) is activated by fluid pressure within the mandrel to axially move a piston (50) positioned radially outward of the mandrel to release the running tool from the liner.

An upper seal body 64 may include threads for engagement with the metal seal body. According the method of the invention, an initial elastomeric seal is first formed, and fluid pressure is applied from above to set the high temperature metal seal.

摘要： A liner hanger running tool (120) includes improvements to the running tool release mechanism, the packoff bushing, and the packer setting assembly. A method is provided for reliably releasing a running tool from a liner hanger (110), for allowing stabbing of the running tool packoff bushing (10) into the top of the liner hanger, and for reliably setting the radial set packer element. The port closure member (212) is movable with a tubular body from a port isolation position to an open port position. The tool includes an annular seal assembly and a substantially conical wedge ring having an outer surface configured to radially expand the annular seal assembly. A ball (240) is lowered into a diverter and thus guided into a pocket (286) in one side thereof to permit passage of a pump down plug (180) into a lower wiper plug (181). A slip assembly carried about a liner for lowering into a wellbore includes a C-ring (64), which expands to cause its teeth to engage with the wellbore. A plug holder (10) sub temporarily supports a liner wiper plug, so that a pump down plug may land in the liner wiper plug and be supported from a generally tubular body of the plug holder sub.
