    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： In accordance with the present invention, a plurality of methods and devices are provided for solving important and serious problems posed by lateral (and especially multilateral) completion in a wellbore including methods and devices for isolating a lateral well from other lateral branches in a multilateral well so as to prevent migration of fluids and to comply with regulations regarding the separate production of different production zones. Various methods and devices are provided for fluid isolation of a lateral well from other lateral wells and for separate production from a lateral well without commingling the production fluids. These methods include the use of a side pocket mandrel, whipstocks with sealable bores and valving techniques wherein valves are located at the surface or downhole at the junction of a particular lateral.

    摘要： Casing valves for selective well stimulation and control. A well system includes at least one valve interconnected in a casing string operable via at least one line external to the casing string to selectively control fluid flow between an exterior and interior of the casing string, and the casing string, valve and line being cemented in a wellbore. A method of selectively stimulating a subterranean formation includes: positioning a casing string in a wellbore, the casing string including spaced apart valves operable via a line to selectively control fluid flow between an interior and exterior of the casing string; and for each of multiple intervals of the formation in sequence, stimulating the interval by opening a corresponding one of the valves, closing the remainder of the valves, and flowing a stimulation fluid from the casing string into the interval.

    摘要： A metal to metal seal for downhole tools. A sealing device includes a metal seal. A nonmetal seal may be used to bias the metal seal in a radial direction in response to a pressure differential applied to the sealing device. A well tool includes a housing assembly, a closure member and the sealing device. Both of the metal and nonmetal seals contact a selected one of the housing assembly and closure member when the closure member blocks flow through the housing assembly. A method of sealing between the housing assembly and closure member includes the step of displacing the closure member to relieve the pressure differential, the metal seal continuing to seal against the pressure differential until the nonmetal seal no longer seals between the housing assembly and the closure member.

    摘要： An airhammer embodies an outer housing structure connectible to a rotatable drill pipe string through which compressed air is conducted. A hammer piston reciprocates in the housing structure, compressed air being directed alternately to the upper and lower ends of the piston to effect its reciprocation in the structure, each downward stroke inflicting an impact blow upon the anvil portion of an anvil bit extending upwardly within the lower portion of the housing structure. Upon elevating the airhammer off the bottom of the bore hole being drilled, the anvil bit drops downwardly of the housing structure to open one or more air bleeding grooves in the anvil bit, compressed air in the housing structure bleeding quickly through such grooves and preventing or stopping the hammer piston from reciprocating and impacting against the anvil bit. A step is also placed in the bit at the junction between its head and shank to break the stress wave, incident to the hammer piston striking the anvil bit, before the wave reaches the bit head, thereby reducing the induced stress at the head and shank junction, which increases considerably the fatigue life of the bit, thereby preventing breaking of the shank at its junction with the bit head.
