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： 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 sleeve valve assembly featuring a cylindrical housing within which a sleeve valve is axially slidable within a radially expanded section of the housing. The radially expanded section of the housing presents an inwardly extending stop shoulder at one point along its length and an annular expansion notch at another point. The sleeve valve includes a radially projecting chamfered boss about its circumference. A portion of the sleeve valve is longitudinally slotted so as to form collets. An outwardly biased C-ring is disposed about the sleeve valve within the radially expanded section. The C-ring is initially disposed to be free to travel axially along the radially expanded section between the boss and the stop shoulder. As the sleeve valve is moved toward an open position, the boss, C-ring and stop shoulder engage each other such that the sleeve valve is releasably snagged against further axial movement toward the open position. A significant axial force upon the sleeve valve is required to effect unsnagging. Upon application of increased axial force, the collets of the sliding sleeve are forced radially inward to permit the boss to slip past the C-ring.An exemplary stimulation tool incorporating the sleeve valve assembly is described which permits acid to be selectively communicated into the surrounding formation. A stimulation tool constructed in accordance with the present invention is particularly useful for acid stimulation applications in horizontal well conduits as the snagging feature of the sleeve valve assembly provides a positive indication that lateral acid flow ports within the shifter tool have been placed adjacent complimentary flow ports in the surrounding housing.

摘要： A production nipple is suspended within an uncased bore hole in a slimhole/monobore completion. A deposit of cement is conveyed through the nipple and is spotted in the annulus across the face of the uncased well bore, with the nipple and cement deposit thereafter being perforated by a small diameter perforating gun. The production nipple has a thin walled section which is characterized by reduced resistance to perforation by a shaped explosive charge. The perforating gun is accurately positioned in registration with the dedicated nipple section by an annular locator slot formed on a coupling sub, which is engagable by a resilient latch arm carried by the perforating gun.

摘要： A linear indexing tool is operably supportable on a tubing string in a subterranean wellbore and has a tubular housing structure within which a tubular mandrel is coaxially and slidably disposed. An indexing structure is operable by tubing pressure to sequentially drive the mandrel through a plurality of axial travel increments in response to a corresponding successive plurality of tubing pressure forces exerted on the indexing structure. Pressure diversion apparatus is operative to permit flow of pressurized fluid from within the housing structure to an external, pressure-actuatable device, such as a packer, only after the mandrel has been driven through at least two of its axial travel increments. Accordingly, the internal tubing pressure may be elevated to a test level thereof, thereby driving the mandrel through its first axial travel increment, without actuating the external device. A subsequent tubing pressure reduction and re-elevation may then be used to index the mandrel through another axial travel stroke to cause the internal tubing pressure to be operably diverted to the external device.
摘要翻译：线性分度工具可操作地支撑在地下井筒中的油管柱上，并且具有管状壳体结构，其中管状心轴同轴且可滑动地设置。分度结构可通过管道压力操作，以响应于施加在分度结构上的相应的连续多个管道压力，顺序地驱动心轴通过多个轴向移动增量。只有在心轴已经被驱动通过其轴向行程增量中的至少两个之后，压力转向装置可操作以允许加压流体从壳体结构内部流动到外部可压力致动的装置，例如封隔器。因此，内部管道压力可以升高到其测试水平，从而驱动心轴通过其第一轴向行程增量，而不致动外部设备。然后随后的管道压力降低和再升高可以用于通过另一个轴向行程行程将心轴分度，以使内部管道压力可操作地转移到外部装置。

摘要： A longitudinally spaced series of tubular nipple structures are installed in a well flow conductor operatively extended through a subterranean well bore. Each nipple structure has a thinned-wall, increased interior diameter longitudinal section through which a plurality of fluid flow openings laterally extend, and an interior side surface annular tool locator recess, with each such recess having a profile different than those of all of the other tool locator recesses. The thinned-wall longitudinal sections of the nipples facilitate the formation of the flow openings therein. To seal off the flow openings in any selected one of these longitudinal nipple sections, a radially expandable tubular metal patch is supported on a setting tool which is lowered into the well flow conductor. A locator member complementarily and lockably receivable by the locator recess of the selected nipple is also supported on the tool. When the locator member snaps into releasably locked engagement with such locator recess, the patch member is automatically positioned in a predetermined longitudinal orientation coaxially with the longitudinal nipple section whose flow openings are to be sealed off. An expander portion of the setting tool is then pulled through the patch member to radially expand it into sealing engagement with the interior side surface of the selected longitudinal nipple section. Due to the increased interior diameter of the longitudinal nipple section, the tubular patch member installed therein does not decrease the drift diameter of the well flow conductor.

摘要： A subsurface well flow control system includes a series of movable sleeve type flow control devices installed in a well flow conductor at various fluid-containing fracture zones, and a shifter tool movable through the conductor and operable to selectively shift any selected number of the sleeve portions of the flow control devices, in either direction between their open and closed positions, without removing the tool from the conductor. Radially retractable anchor and shifter key sets are carried in side wall openings of the tool body, and are respectively configured to be lockingly engaged with interior side surface groove sets on the body and movable sleeve portions of any of the flow control devices. The key sets are spring-biased radially outwardly toward extended positions, and an electromechanical drive system disposed within the tool body is operative to radially retract the key sets, and to axially drive the shifter key set toward or away from the anchor key set. This permits the tool to be moved into and through any of the flow control devices in either axial direction, locked to the device, operated to shift its sleeve portion fully or partially in either direction, and then disengaged from the flow control device and moved to any other one of the flow control devices to shift its sleeve portion. Interengaged V-threads on the body and sleeve portions of each flow control device facilitate the releasable retention of the sleeve portion in a partially shifted position.
