摘要： Disclosed are apparatus and method of closing a conduit against fluid flow in at least one longitudinal sense, and selectively disengaging and reengaging the closure mechanism without removing the closure mechanism from the conduit. In a particular embodiment, a valve assembly may be selectively anchored and sealed to a well packer, or disengaged therefrom. The valve assembly is manipulated by an operating tool to which the valve assembly is anchored in the well when the valve assembly is disengaged from the packer.

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： 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 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： An expandable slip ring is used to secure attachment of an expanded tubular to a surrounding tubular. It features elongated generally axially oriented openings separated by narrow segments. As a swage is advanced within a tubular that has the slip ring outside it the narrow segments or tabs expand and can break but the ring is still held to its shape as the expansion progresses due to the integrity of other tabs that can subsequently break as the swage advances within the tubular that is surrounded by the slip ring. The integrity of the slip ring is enhanced for storage and run in while the expansion characteristics are more uniform as the ring retains some structural integrity during much of the expansion process.

摘要： An expandable tubular pin and box connection is described having a feature of trapping the pin nose after preferably deforming the pin nose plastically in an outward direction away from the longitudinal axis of the connection. The box end is held away from the pin wall before expansion so that its tendency to curl inwardly upon expansion causes it to bend against the pin wall for sealing with it. The thread profile is also optimized to reduce flank separation as a result of expansion.
