    摘要: A subterranean well tool seals along a section of a wall of the well and is carried on a conduit into the well. A plurality of anchoring elements and seals are provided for respective anchoring and sealing engagement along the wall of the well in concert and substantially concurrently with one another when the tool is shifted to the set position. When the well tool moves to the set position, a portion of the mandrel separates and is retrieved from the well bore, allowing the well tool to be reduced in overall length. The anchoring elements are sandwiched in between first and second, or upper and lower, sets of seals.

    摘要: A single trip multizone time progressive well treating method and apparatus that provides a means to progressively stimulate individual zones through a cased or open hole well bore. The operator can use pre-set timing devices to progressively treat each zone up the hole. At each zone the system automatically opens a sliding sleeve and closes a frangible flapper, at a preselected point in time. An adjustable preset timing device is installed in each zone to allow preplanned continual frac operations for all zones. An optional “Stand-Down-Mode” can be integrated into the timing system so that if pumping stops the timers go into a sleep mode until the pumping resumes. The apparatus can consist of three major components: a packer, a timing pressure device, and a sliding sleeve/isolation device. The packer may be removed.

    摘要: A separable fluid pressure activated firing mechanism for a perforating gun comprises a pressure-operated tubing valve, a packer, and a tubular housing assembly defining a plurality of fluid pressure chambers therein. The first chamber contains a light density, clean, compressible fluid which is subject to well annulus pressure above the packer to provide a reference pressure. A second chamber sealably mounts a piston-type firing pin, which is normally secured by a locked latch in an elevated position above a detonatable primer and the lower portion of said firing pin is exposed to the reference pressure. The latch is unlocked through the application of a predetermined annulus pressure above the packer to a locking piston which moves to unlock the latch and trap the reference pressure in the first chamber. A further increase in said annulus pressure opens the tubing valve. A still further increase in said annulus pressure releases the firing pin from the latch and drives the firing pin downwardly to detonate the primer. Additional features of the disclosure are the provision of a crossover tool between the packer and the tubular housing assembly to permit underbalance perforating, the provision of a detachable connection between the cross-over tool and the packer, and the provision of a shiftable sleeve valve effecting the closing of a connection from the packer bore to the annulus upon disconnection of the packer from the cross-over tool.

    摘要: A well perforating apparatus includes an underbalancing valve for opening ports in a tubing string immediately subsequent to the firing of a perforating gun, and comprises a hollow conduit having at least one pair of axially aligned, and radial holes traversing the wall of the conduit. A frangible member has its end portions slidably and sealably mounted in such holes and is therefore disposed transversely to the path of a detonating bar which is dropped to initiate the firing of the perforating gun. Upon breakage of the frangible member, the ends of the bar are forced inwardly out of the holes by the fluid pressure differential existing between the interior and exterior of the conduit due to the underbalanced fluid pressure condition achieved in the tubing string prior to firing the perforating gun.

    摘要: A redundant firing mechanism for a perforating gun utilized in subterranean wells comprises a hollow housing assembly incorporating two spaced primer charges disposed in vertically spaced relationship. A fluid pressure chamber is defined within the hollow housing assembly and is closed at the top end of the assembly by a frangible barrier disc. A fluid pressure actuated hammer is provided to impact upon the lowermost one of the primers in response to fluid pressure developed in the fluid pressure chamber. In the event that the lowermost primer does not detonate, a detonating bar may then be dropped through the tubing string to break the frangible barrier and impact upon a second hammer disposed in overlying relationship to the second primer.

    摘要: A method and apparatus effecting the perforating of a well casing and the gravel packing of the perforated areas of the well casing with one trip into the well of a combined perforating and gravel packing apparatus. This desirable objective is accomplished by a perforating gun construction permitting complete flexibility to adjust in the field the number of horizontally and vertically spaced shaped charges through the provision of a polygonal carrier having vertically spaced holes provided in each of its planar sides to accommodate vertically spaced horizontal groups of shaped charges with the charges in one horizontal group being angularly displaced relative to the charges in a vertically adjacent horizontal group. Additionally, the crossover mandrel employed in the gravel packing operation provides, in its run-in position, a continuous axial passage through its entire length, permitting a detonating device to be placed therethrough to actuate the perforating gun. Subsequent to the perforating operation, a ball is dropped and seated on an annular sleeve carried within the hollow mandrel which permits the development of internal pressure within the mandrel. Such internal pressure is employed not only to effect the setting of a fluid pressure actuated packer but also to shift the ball supporting sleeve downwardly and uncover a crossover port in the mandrel which permits the gravel packing operation to be carried out conventionally.

    摘要: A method and apparatus for releasing a subterranean well perforating gun from a tubular string after firing of the subterranean well perforating gun. The apparatus comprises two telescopically inter-related tubular assemblies which are interconnected for axial co-movement solely by a plurality of radially shiftable latching elements. Such latching elements are normally maintained in a locked position by an annular piston. One end of the annular piston is exposed to gas at surface ambient pressure and the other end is exposed to the gas pressure generated in the perforating gun by its discharge and subsequently to the well fluid pressures produced by flow of well fluids through the perforations. The movement of the annular piston under such fluid pressure forces permits the locking elements to be cammed radially inwardly and release the connection between the tubular tool string and the perforating gun without any action on the part of the operator.
