    摘要: An apparatus and method are provided for completion of a horizontal section of a subterranean well. The apparatus comprises a first packer assembly which is settable in the well by longitudinal manipulation of a tubular workstring. A second packer is carried into the well on the workstring and is settable by application of hydraulic pressure through the workstring. A perforating gun is carried into the well on and in communication with the workstring, together with a gun retractor for telescopically retracting the perforating gun. A valve is also provided for selective communication between the exterior and the interior of the apparatus and is manipulatable to the open position to effect, for example, a fluid flow path from the production zone to the top of the well for transmission of production fluids in the well.

    摘要: A packer assembly is provided for use in a subterranean well and settable only by longitudinal manipulation of a tubular workstring. The assembly has an outer housing and a seal assembly with anchoring slips carried by the housing in retracted position and movable to expanded position along the wall of a casing or the like. A longitudinally extending central mandrel telescopes within the housing. Orienting and setting pins are provided for initial receipt within orienting and setting slots with the setting pins being moved to the orienting slot to permit setting of the packer. The seal assembly and anchoring slips are maintained in retracted position and are responsive to a variation in internal diameter between a first and second tubular conduit to thereafter permit the manipulating device to move the seal assembly and the anchoring slips to expanded position within only the second tubular conduit which has a diameter less than that of the first tubular conduit.

    摘要: A well packer has a metal seal which seals between the packer mandrel and the casing. The metal seal includes a seal sleeve located on the exterior of the mandrel. The sleeve has an inner wall and an outer wall radially separated by a channel. The inner channel is initially separated from the exterior of the mandrel by a clearance. An energizing ring is sizably mounted to the mandrel for axial movement relative to the mandrel. Initially, the energizing ring will be located at the entrance of the channel. An actuating device moves the energizing ring into the channel, wedging the walls of the seal sleeve apart. The inner wall seals against the mandrel. The outer wall seals against the casing.

    摘要: The apparatus of the present invention is a retrievable packer which provides for release between a mandrel and a packing element support structure by virtue of a rotational movement The apparatus is configured so that the packer can be set by letting up on a tubing string or, in some applications where sufficient weight is unavailable, by pulling up on the tubing string. The slips feature a locking mechanism to secure the packing element against the wellbore W. A release mechanism is provided to defeat the lock mechanism and to act upon the slips to draw them inwardly so the apparatus can be removed from the wellbore W.

    摘要: A subterranean well casing float tool is comprised of a tubular metal housing which is securable to a well casing conduit. Varing means are implaced within the housing, with substantially all of the components of the valving means, save a biasing means, are thermosetting. The valving means has a thermosetting frame and valve head and valve seat means relative to the frame. A biasing member, such as a compressed spring is used for urging the valve head toward the valve seat to a closed position. A compartment including the valve head is provided for enclosure around the biasing means when the valve head is moved fully away from the valve seat to protect the spring from errosive turbulent fluid flow when the valve head is in the open position relative to the seat. The valving means is directly secured to the housing by means of thread members having profiled shear surfaces such that the shear area of the valving means is substantially greater than that of the metal housing.

    摘要: A well control system for providing surface control of downhole production tools in a well. The well control system is capable of detecting well conditions and of generating command signals for operating one or more well tools. An electric conductor transmits electric signals, and a hydraulic line containing pressurized hydraulic fluid provides the power necessary to operate downhole tools. The invention provides a unique system for providing redundant conductors and redundant hydraulic lines to the well tool to continue operation if an electric conductor or hydraulic line becomes disabled. The well control tool also permits the selective operation of multiple production zones in a producing well.

    摘要: A pack-off tubing hanger is shown for use in a tubing string extending from a well surface location to a downhole location within a well casing. The hanger body includes an external packing element and gripping slips which support the hanger body within the surrounding casing. A hydraulic line communicates hydraulic pressure from the lower end of the hanger to a setting chamber to hydraulically set the packing elements and actuate the gripping slips. The tubing hanger is releasable by a straight upward pull upon the tubing string extending from the well surface to the tubing hanger.

    摘要: The invention provides an apparatus for limiting tension produced in a tubular string extending from a packer set in a subterranean well to the well surface. Such apparatus comprises a receptacle secured to the packer and defining an elongated seal bore, and a mandrel telescopically and sealably related to the seal bore, the mandrel being connected to the bottom end of the tubing string. In one embodiment, a collet, incorporated in the receptacle for cooperating with an abutment formed on the mandrel, thereby securing the mandrel and the receptacle in a telescopically contracted position until sufficient tensile force is exerted on the mandrel to cause the collet arms to be expanded by the abutment to permit upward movement of the mandrel relative to the receptacle.
