摘要： Disclosed is a surface controlled subsurface safety valve for deep well service. Communication of control fluid to the subsurface safety valve is controlled at a subsurface location in close proximity to the valve. Responsiveness of the subsurface safety valve to decreases in control pressure is thereby increased and the valve's closure speed is also increased. This abstract of the disclosure is neither intended to define the scope of the invention, which, of course, is measured by the claims, nor is it intended to limit the invention in any way.

摘要： A packer includes one dual, or double acting, slip and a single acting slip positioned on a mandrel on opposite sides of a packing element and a setting cylinder. The single acting slip is designed to resist forces acting on the mandrel in one direction. Setting forces generated by the setting cylinder are coupled to the mandrel through a releasing sleeve. When the releasing sleeve is decoupled from the mandrel, the slip setting forces on both slips and the packing element are released and the packer can be retrieved from a well. In a preferred form, the releasing sleeve may be decoupled from the mandrel by multiple means.

摘要： Apparatus and corresponding methods are disclosed for controlling fluid flow within a subterranean well. In a described embodiment, a longitudinally spaced apart series of selectively set and unset inflatable packers is utilized to substantially isolate desired portions of a formation intersected by a well. Setting and unsetting of the packers may be accomplished by a variety of devices, some of which may be remotely controllable. Additionally, a series of fluid control devices may be alternated with the packers as part of a tubular string positioned within the well.

摘要： A coupling 10 for use with composite coiled tubing 12 connects the coiled tubing 12 to a tool or other tubing member. The coupling 10 may include a female coupling component 26 and a male coupling component 28, with a substantially flush internal bore through the coupling 10 concentric with the coiled tubing. The female component 26 may include a tapered, negative flank thread profile 32 for engagement with the coiled tubing 12, and preferably provides a fluid tight seal and axial joint strength substantially as strong as the coiled tubing 12. Another embodiment of the coupling 70 may include a smooth tapered inner surface 76 for bonding engagement with the coiled tubing 12. In addition, a double male flush joint adapter 80 may be used to connect multiple strings of composite coiled tubing 12 and may also provide a substantially flush internal joint.

摘要： A slip having a passageway for installation of lines therethrough and associated anchoring device provides uniform gripping engagement with a wellbore without unduly stressing the slip or casing, and without requiring complex manufacturing and assembly. In a described embodiment, a slip has slip segment, transitional and C-ring axial portions. The slip segment portion includes multiple axially elongated and circumferentially spaced apart slip segments. Each slip segment is attached to an axial end of the C-ring portion by a transitional element. When the slip is extended into engagement with a wellbore, the transitional portion permits the slip segments to flex and uniformly apply a gripping force to the wellbore.

摘要： Pumpdown toolstring for performing operations requiring application of power downhole in horizontal or high-deviation oil or gas wells, comprising an elongate toolstring element (30), locomotive devices (31, 32A) on said toolstring element, with at least one locomotive device (32) provided at a trailing or top end of the toolstring element (30). The toolstring element (30) is tubular and has a closed leading or bottom end, whereas it is open at the opposite, top end. The leading locomotive device, (31) adapted to pull the toolstring element during pumping down, has a seal for co-operation with a seat at a no-go or nipple assembly at the bottom end of a tubing from which an extension tubing extend into the horizontal or high-deviation well. The leading locomotive device (31) sealingly surrounds the toolstring element (30) and allows sliding of the toolstring element there-through when engaging the seat. The toolstring element (30) has a safety bypass valve (80) near the at least one locomotive device (32A) at the top end of the toolstring element and check valve (70) between the bypass valve (80) and the at least one locomotive device (32A).

摘要： A system for controlling flow in a well conduit including a landing nipple in the well conduit and a standing valve, which after landing in the landing nipple may be retrieved or expended from the landing nipple. The standing valve permits upward flow and prevents downward flow through the landing nipple and conduit and has a resilient seal which expands into a groove in the landing nipple to provide limited resistance to upward flow moving the standing valve upwardly out of the landing nipple. Sufficient weight on the standing valve or pumping down the conduit with sufficient pressure releases a landing ring on the standing valve to retract, permitting the standing valve to be moved downwardly and expended out of the landing nipple.
