    摘要: Disclosed is a hydraulically operable well packer for releasable setting within a well conduit, including a seal assembly for sealing the packer to the conduit and an anchor assembly for anchoring the packer to the conduit. The seal assembly includes sealing members for engaging the conduit as well as secondary sealing members for engaging a central mandrel of the packer, both sets of sealing members being constructed of material which permits the mandrel to remain sealed to the well conduit in the presence of high temperatures. The packer may be released by straight longitudinal movement of the mandrel relative to the outer packer assembly.

    摘要: A setting tool is shown of the type adapted to be made up in a pipe string for releasably engaging a setting sleeve in a well bore. The setting tool has a mandrel having an upper end adapted to be connected in the pipe string and having a lower end. A setting nut is carried on the mandrel having external connecting threads for engaging mating connecting threads located on the interior of a setting sleeve disposed about the lower end of the mandrel. The mandrel is slidably disposed within the setting nut when the setting nut is engaging the setting sleeve and the mandrel is slidable between an extended running-in position and a weight set-down position.A latch collar having at least one latch ear is carried on the mandrel exterior. The setting sleeve has at least one end notch adapted to receive the latch ear for preventing relative rotational movement between the connecting threads of the setting nut and the setting sleeve when the mandrel is in the extended running-in position and allowing relative movement between the connecting threads when the mandrel is in the weigh-down position to release the connecting threads. Torque override is provided for releasing the latch mechanism upon the application of a predetermined rotational torque to the mandrel to thereby allow relative rotational movement between the connecting threads without the application of downward force to the mandrel. The mandrel is spring biased in the extended running-in position and connected by a shear mechanism to the setting sleeve to prevent inadvertent release of the tool during the running in operations.

    摘要: A seal assembly is disclosed including first and second annular members mutually movable longitudinally to effect a first configuration in which the seal assembly is releasably anchored to a cylindrical body circumscribed by the seal assembly, and a second configuration in which the seal assembly is releasably anchored to a surrounding conduit. Sealing members are carried by the seal assembly to engage the enclosed cylindrical body as well as the circumscribing conduit. Operation of the seal assembly for movement between the first and second configurations is accomplished by manipulation of the cylindrical body which, with the seal assembly anchored to the conduit, is permitted limited longitudinal movement relative to the conduit and seal assembly while maintaining sealing engagement with the seal assembly. A disclosed embodiment includes a well seal assembly, or packer, for sealing a pipe string to a well conduit.

    摘要: A valve used in a drill stem test tool has a ball movable between an open position to allow flow through the drill string for testing and a closed position to block flow. Operating means move the ball between the open and closed positions in response to pressures in the well annulus. A nitrogen filled pressure chamber and pressure balancing piston compensate for variations in annular pressure as the tool is being lowered into position in the well. Actuating means including a weight operated sleeve are operated from the surface to overcome the compensating effect of the pressure balancing piston to allow the ball to be rotated to the open position. The ball is spring biased toward the closed position by a coil spring located inside the pressure chamber. Relieving pressure in the annulus causes the spring to close the ball.

    摘要: Disclosed is a well packer for releasable setting within a well conduit, including a seal assembly for sealing the packer to the conduit and an anchor assembly for anchoring the packer to the conduit. The packer is set in stages by hydraulic pressure. The seal assembly is extended, and locked, in sealing configuration; the anchor assembly is then set, and locked, in gripping engagement with the conduit. The packer is released by longitudinal movement of a central mandrel relative to the seal and anchoring assemblies. The release of the packer also occurs in stages, with the seal assembly unlocked and released from its set configuration followed by like operations relative to the anchor assembly. A hold-down system prevents premature release of the packer by securing the mandrel against such relative longitudinal movement.

    摘要: A retrievable well packer is shown of the type adapted for releasable setting within a well conduit. The packer has a central mandrel extending within an outer assembly, seal members carried on the outer assembly for sealingly engaging the conduit, anchoring slips carried on the outer assembly for grippingly engaging the conduit, and a hold down piston-collet assembly for releasably connecting the mandrel to the outer assembly to maintain sealing and gripping engagement between the seal members an anchoring slips and the conduit. The collet is movable between a locking position in contact with the piston whereby the mandrel is connected to the outer assembly, and a release configuration out of contact with the piston whereby the mandrel is released for longitudinal movement relative to the outer assembly. A shear wire fixes the piston in the locking configuration in contact with the collet. The shear wire has a preselected shear index, whereby a predetermined increase in well annulus pressure over pressure inside the central mandrel shears the shear wire to release the hold down piston.

    摘要: The invention comprises a plug assembly for selectively closing and opening a flowway in a tubular conduit. The apparatus includes a seating body having a main passage and adapted to be mounted in the conduit with the main passage in register with the conduit flowway. The seating body defines a seat for receipt of a plug for closing the main passage and supporting a pressure differential across the seat. The apparatus further includes a release control mechanism operative upon the presence of a pressure differential across the seat in excess of a given magnitude to open a bypass passageway bypassing the seat and plug to permit a relatively slow decrease in the pressure differential across the seat.

    摘要: The present invention is an interprocess communications (IPC) system and method which utilizes shared memory to transfer message contents and a separate, efficient notification mechanism to perform message control functions. The present invention supports robust, asynchronous communications between potentially large number of software application processes residing on any single or tightly-coupled multiple processor arrangement supporting shared memory between the processes. The present invention is a combination of existing IPC mechanisms available in most commercially available UNIX operating systems. The IPC mechanism utilizes the presently available UNIX shared memory IPC mechanism for transferring message contents and the presently available UNIX datagram socket IPC mechanism for message control and notification. The IPC mechanism may be adapted to other operating system environments. The IPC mechanism performs a controlled shutdown of the interprocess communications associated with a user process which has ceased executing. The shared memory allocated for the IPC mechanism is periodically audited to reclaim lost shared memory blocks due to user process failures.
