    摘要： The present inventions contemplate an improved well tool actuator and method that does not require more expensive downhole equipment and can be utilized with limited actuation pressures. According to the improved well tool actuator and method of the present inventions, a fluid pressure intensifier is placed in the well and coupled to the downhole device to be manipulated. By using a fluid pressure intensifier the actuation pressure can be increased to a pressure sufficient to operate or manipulate the downhole device without the necessity of increasing the tubing pressure. According to the present invention the actuation pressures supplied by the intensifier can exceed the safe operating rated pressures of the well tubing and equipment. The well tool actuators of the present invention are self-contained in that they are powered from the tubing fluid pressure itself without a high-pressure hydraulic or electrical connection to the surface. According to the present inventions, subterranean hydraulically actuated well tools can be actuated at higher pressures than the supplied pressure. Fluid pressure intensifiers circuits can be assembled in and carried downhole with the actuation tool and removed once the actuation process is complete. Also, fluid pressure intensifier circuits can be assembled as a part of the well tool and operated remotely.

    摘要： A 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 moved through the jointed tubular structure on an elongated positioning member, representatively a slick line, through a series of joints to be logged. As the detector passes through each joint it electromagnetically senses the joint and responsively generates an electric output signal. The output signal is used to momentarily cause a drag structure portion of the detector, in cooperation with the interior side surface of the tubular structure, to momentarily create a detectable tension change in the elongated positioning member. Alternatively, a pyrotechnic or compressed gas device may be used to create the detectable changes in response to the generation of the electrical output signals. These tension changes, which may be either tension increases or tension decreases, 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 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： Apparatus and methods are provided for anchoring within tubular structures and releasing therefrom. In a described embodiment, a packer includes multiple debris barriers, which are deployed when slips of the packer are radially outwardly extended. The debris barriers prevent debris from settling about the slips, thereby enhancing convenient retrieval of the packer. Use of the debris barriers may also permit control over how the slips are extended.

    摘要： A gas lift valve mandrel especially adapted for mounting on reeled tubing used in a well including a mandrel body in at least two sections comprising a gas lift valve adapter and a clamp which are secured together around the tubing, the adapter including structure for mounting a gas lift valve and flow passages communicating into the gas lift valve and into a bore through the mandrel through which the tubing extends, the flow passage in the adapter communicating with a port in the tubing when the mandrel is mounted on the tubing and further including a seal in the adapter for sealing with the tubing around the port into the tubing. An alternate form of the mandrel includes a pipe plug hole and a pipe plug in the adapter for access to the flow passage in the adapter to drill the port into the tubing when the mandrel is mounted on the tubing during the mounting procedure. The mandrel is readily secured on the tubing at desired locations as the tubing is run into a well.

    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.
