    摘要: A hydraulic well tool for running into a flow conduit of a well on a handling string, such as reeled tubing or jointed pipe, for generating and applying an axial force to an object in the well, the well tool including an anchoring mechanism actuatable by fluid pressure in the handling string for anchoring the well tool in the flow conduit, this well tool further including a piston/cylinder arrangement also actuatable by fluid pressure in the flow conduit for moving the aforementioned object. The object may be a well tool, a sliding sleeve, a fish, or other well tool. The hydraulic well tool may be provided with a suitable device to permit increasing the pressure in the handling string for actuation of the anchoring mechanism and the piston/cylinder arrangement. Devices suitable for such purpose include a flow restrictor, ball and seat, velocity check valves, plugs, or the like devices. The displacement of such object is brought about hydraulically while the well tool is anchored in the flow conduit and without axially stressing the handling string. The anchoring mechanism includes piston type anchor members each formed with a sinusoidal seal ring recess at its inner end for increasing the stroke of the anchor members, and with a recess running across the inner face of the anchor member in a direction parallel to the longitudinal axis of the well tool to avoid obstructing the longitudinal body bore.

    摘要: A pilot operated gas lift valve utilizing a diaphragm formed of polymeric or elastomeric material and exposed to lift gas pressure on one side and atmospheric pressure on the other side, the diaphragm being able to withstand very high differential pressures and endure an extremely great number of operating cycles. The gas lift valve may be provided with an extension on the pilot valve member and this extension is exposed at all times to production fluid pressure, in which case, production fluid pressure will affect the operation of the gas lift valve. Thus, the gas lift valve may be 100 percent sensitive to production fluid pressure and totally insensitive to lift gas pressure, or its sensitivity to production fluid pressure may be as little as about four percent, depending upon the cross sectional area of the extension. Use of the diaphragm in the pilot valve mechanism provides essentially friction free operaton. Use of atmospheric pressure and a spring on the side of the diaphragm opposite the lift gas pressure avoids the effects of downhole temperatures on the pilot valve. Diaphragms formed of Teflon, especially virgin Teflon are disclosed should last for the life of most gas lift wells, and for operation in excess of 100,000 cycles. Also, diaphragms formed of elastomeric materials are also disclosed.

    摘要: In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip and wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip. Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.

    摘要: An annular safety valve system provides a retrievable annular safety valve and packer. In a preferred embodiment, an annular safety valve system has an annular safety valve connected to an upper tubing string extending to the earth's surface. The annular safety valve is initially connected to the hydraulically set packer which has no openings through an inner mandrel thereof. The safety valve is retrievable separate from the packer after the packer has been set. The safety valve is rotated relative to the packer in order to release the safety valve from the packer. As the safety valve is rotated, a setting line of the packer is severed. Other transmission lines, electrical wires, etc. may be severed as well. The safety valve may then be raised to the earth's surface with the tubing above it. A replacement safety valve is also provided for installing in the packer after the prior safety valve is retrieved.

    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: An electromechanical detector structure is used to sense and log the joints in a downhole jointed tubular structure, such as a well bore casing or production tubing, in a subterranean well. The detector is lowered into the tubular structure on an elongated positioning member, representatively a slick line, through a series of joints to be logged, and then pulled upwardly through the joints. As the detector passes upwardly through each joint it electromagnetically senses the joint and responsively generates an electric output signal. The output signal is used to momentarily drive a drag structure portion of the detector into forcible, motion inhibiting contact with the interior surface of the tubular structure. This, in turn, momentarily creates a detectable tension increase in the elongated positioning member. These tension increases serve as mechanical output signals transmitted upwardly through the positioning member, and may be plotted on a strip chart recorder at the surface to record the joint locations and correlate them to the lowered depth odometer readings of the detection system. Using this electromechanical joint detection apparatus, correlative joint logging procedures may be carried out for tool setting purposes without the necessity of utilizing an electrical conductor line.

    摘要: A method and apparatus especially adapted for use with an injection well in which a valve controlled H-member interconnects the two tubings of a two tubing installation and landing nipples are attached to the lower legs of the H-member to receive expendable fluid control means, such as standing valves, in which pressure applied to one tubing to create a pressure differential will move the valve controlling the interconnection between the H-members to open position to permit TFL operations to be carried out in the well and thereafter pressure exerted on a ball supported on the valve member of the control valve for the H-member closes the control valve, and the ball passes through the control valve. The fluid control members in the landing nipples may be ejected either before or after closing of the valve in the H-member.The standing valve shear pins may be sheared without releasing the valves from their supporting shoulders. When pressure approaches equalization the valves will pass through the supporting shoulders.
