摘要： A decentralizer for a diverter, a centralizing guide bushing and a downhole-deployable locating and orienting subsystem. The subsystem is capable of three modes of operation: (a) a running mode in which an actuating mandrel is in a first axial limit position with respect to a common mandrel, the actuating mandrel placing first and second double-acting springs in a stowed position wherein locating and orienting keys are retracted radially inwardly with respect to the common mandrel to shield the locating and orienting keys from substantial contact with a surrounding well flow conductor as the common mandrel traverses therethrough, (b) a locating mode in which the actuating mandrel is in an intermediate axial position with respect to the common mandrel, the actuating mandrel placing the first and second double-acting springs in a deployed position resiliently to bias the locating and orienting keys radially outwardly with respect to the common mandrel to seek a locating and orienting profile on an inner surface of a surrounding honed bore within the surrounding well flow conductor, and (c) a set mode in which the actuating mandrel is in a second axial limit position with respect to the common mandrel, the actuating mandrel directly engaging and stiffly retaining the locating and orienting keys in engagement with the locating and orienting profile thereby to fix the common mandrel in a desired location and orientation with respect to the honed bore.

摘要： A bidirectional disappearing plug member and plug assembly is capable of blocking pressurized fluid flow from opposing axial directions in a flowbore. In a preferred embodiment, the plug member, which blocks flow through the flowbore, may be readily and at least partially dissolved through the application of at least one pressurization and depressurization within a tubing string above the plug assembly. Construction of the plug assembly permits the plug member to be conveniently emplaced in a fluid-filled wellbore by permitting fluid flow around the plug member during the emplacement process. The plug member may then be secured within the plug assembly to block fluid flow from either axial direction. Operation of a plug rupture sleeve or mandrel, for at least partially dissolving the plug member, may be controlled by a ratchet assembly or linear indexing apparatus requiring multiple pressurizations and depressurizations before the plug member is exposed to wellbore fluids and thereby at least partially dissolved.

摘要： An improved full bore nipple and associated lock mandrel provides enhanced sealing capability in tubing strings positioned in subterranean wells. In a described embodiment of the full bore nipple, a nipple body has a recessed seal surface and a latch profile formed on an internal bore of the body. In a described embodiment of the lock mandrel, an expander sleeve radially outwardly expands a circumferential seal to sealingly engage the recessed seal surface, locks a series of keys into the latch profile, and displaces another seal to sealingly engage an outer housing, when the expander sleeve is displaced axially downward relative to an inner mandrel of the lock mandrel.

摘要： In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls into and is retained in an underlying gun catcher portion of the workstring. While an overpull force is maintained on the workstring above the perforations, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone. After stimulation of the production zone, the workstring and the spent perforation gun that it retains are pulled up, with the upwardly moving workstring positioning a sliding closure device inwardly over the perforations to isolate the stimulated production zone until the well is readied for production. Illustrated alternate embodiments include the use of a low debris casing gun in place of the drop-off type perforating gun, the use of pre-formed wide wall perforations in the workstring side wall, and a one-trip perforation and production flow creating method in which the production zone stimulating step is eliminated.

摘要： A retrievable well lock for use within a subterranean member is used in cooperation with a tool for setting the lock. The lock will include an actuation assembly which is operable in response to longitudinal movement between portions of the lock. The setting tool will preferably include a power source within a housing assembly which can be selectively coupled to or decoupled from the lock assembly. The power source is associated with the setting tool through an activation assembly which will cause movement of a movable mandrel within the setting tool facilitating the selective actuation of the lock.

摘要： A system and a plug for plugging a well conduit. The plug includes a lock mandrel and a valve. There is a prong releasably connected in the plug. A running tool is adapted to releasably connect to the plug lock mandrel and prong. After the plug is lowered into a well conduit and installed in a landing nipple, upward releasing force on the running tool moves the prong upwardly closing the valve and plug to flow and the prong locks in valve closed position. Later, the prong may be disconnected and raised from the plug to surface, permitting pressure outside and inside the plug to equalize for retrival of the plug.
