摘要： A detonator bar has an outer housing, an inner housing connected to the outer housing by at least one first frangible member, an explosive charge disposed in the inner housing, and a firing piston with firing pin held in the inner housing by at least one retaining dog and at least one second frangible member. Operation occurs in response to a relatively small impact force between the detonator bar and a perforator or other explosive object located in a subterranean well. This relatively small impact breaks the at least one first frangible member. Thereafter, a fluid pressure existing in the subterranean well, such as a hydrostatic pressure within a tubing string on which a perforator is conveyed, is used to exert a sufficient force to break the at least one second frangible member after the at least one retaining dog has been released by downward movement of the outer housing relative to the inner housing, which relative movement occurs only after the initial impact force has broken the at least one first frangible member.

摘要： A method and apparatus for perforating a subsurface formation in a pumped well. An assembly is provided which facilitates both the support of a pump in a tool string and the convection of fluid, and pressures, around the pump in the tool string. A firing head associated with the perforating gun is actuated by a pressure of differential between the tubing string bore and the wellbore annulus. This pressure differential is achieved by a downhole pump which pumps fluid out of the wellbore into the tubing string bore.

摘要： Systems and methods for surging fluid downhole in an earth borehole, as well as tools especially adapted for use in such systems and methods, are disclosed. In a system for surging fluids, upper and lower valves both operated through the use of annulus pressure define the upper and lower extremities of a surge chamber. In a multiple surge system, first and second surge chambers are provided and a further valve is operative to surge fluids from the first surge chamber into the second surge chamber. A valve is disclosed having a longitudinal passageway initially closed by a breakable closure member. The valve is opened by breaking the closure member, and removing the broken closure member from the longitudinal passageway. The valve is operated by pressure differential between annulus pressure and atmospheric pressure which serves to accelerate a massive cutter member into the closure member for opening it. Also, a fluid pressure actuated apparatus especially useful in operating the upper valve is disclosed. A mechanism enables the operation of the valve in response to the elevation of fluid pressure within the valve, so that the operation of the upper valve with the use of annulus pressure is independent of the operation of the lower valve.

摘要： A tool for activating the firing head of a perforating gun located below a packer by applying pressure to the upper well annulus while maintaining an unimpeded bore between the perforating gun and the pipe string. The tool is provided with a flow valve to prevent flow through the flow bore when closed, and a circulation valve which permits fluid flow from the upper annulus into the flow bore when open and a means of switching the valves so that when one is open the other is closed. A method of using the tool to complete a well is also disclosed.

摘要： A system for perforating a well with an annulus pressure firer is provided by the present invention. A pressure responsive means is positioned in a tubing string uphole a packer and includes a piston movable in response to a pressure differential between the upper annulus pressure and the pressure inside the tubing string. The movement of the piston is transferred through a second, concentric tubing string to a firing head on a perforating gun below the packer. The system includes a means for simultaneously decoupling the concentric tubing strings below the packer to drop the perforating gun to the bottom of the well.

摘要： Methods and apparatus are provided for setting a packer and for placing a seal assembly into the packer bore on a single trip into the borehole. Such apparatus includes a releasable mechanism coupling the seal assembly in fixed relation to the packer until such time as the packer is at least partially set. Methods and apparatus of the present invention also include a mechanism for hydraulically setting a packer without any manipulation of the tubing string. A pair of hydraulic pistons are utilized to move in opposite directions and exert forces on both a packer actuating sleeve and the packer body to set the packer. Methods and apparatus are provided for actuating well tools in response to the hydrostatic pressure in the well. Through use of such apparatus, a chamber at atmospheric pressure is placed in communication with one side of a hydraulically movable member, the other side of which is exposed to hydrostatic pressure. The low pressure of the atmospheric chamber causes movement of the member to operate the well tool.

摘要： An actuating tool which is conveyed into a tubing string to attach to portions of an emplaced perforating gun. The tool includes an actuator with an electronic delay timer and an explosive device. The tool attaches to an emplaced perforating gun and detonates it by initiating an explosive charge along a complete explosive pathway formed between the actuator and gun, the actuator includes a tandem piston arrangement functional at most existing hydrostatic pressure levels, but nonfunctional at or near the surface of the wellbore. The tool may be withdrawn from the tubing string for a backup detonation tool to be placed into the tubing string to detonate a secondary firing head.

摘要： Methods of perforating a well using coiled tubing conveyed perforating guns are disclosed. A perforating tool string includes a coiled tubing string, a perforating gun, a releasable gun hanger, and a pressure responsive release connecting the coiled tubing string to the perforating gun. The perforating tool string is lowered into place within the well and then the gun hanger is actuated by reciprocating motion of the coiled tubing string without rotating the coiled tubing string, thereby setting the gun hanger in the casing. Fluid pressure is then increased in the coiled tubing string to actuate the pressure responsive release to release the coiled tubing string from the perforating gun. The coiled tubing string and pressure responsive connector may then be retrieved from the well prior to firing the perforating gun. The perforating gun is subsequently fired by a pressure responsive firing head to perforate the well casing, and the perforating gun then automatically drops to the bottom of the well casing.
