摘要： A perforating gun for use in a well casing, the gun having a gun carrier extending along a longitudinal axis; plural shaped charges located inside the gun carrier, in groups of three, a first group of three shaped charges being positioned in a first single plane, transverse to the longitudinal axis, and a second group of three shaped charges being positioned in a second single plane, transverse to the longitudinal axis; and a charge holder configured to carry the plural shaped charges, the charge holder configured to be inserted into the gun carrier. The first and second groups of three charges are spaced along the longitudinal axis so that a third single plane, transverse to the longitudinal axis, intersects each of the six shaped charges of the first and second groups of three charges, to achieve an ultra-short, high-density, perforating gun.

摘要： The present invention provides a method and apparatus for plugging a wellbore in a trip saving manner. In one aspect, the invention includes a cement retainer disposed on a run-in string and a radially expanded perforating assembly disposed below the cement retainer. In a single run, the apparatus provides for perforating a wellbore and squeezing cement through the perforations and into the formation therearound. In another aspect, a method of plugging the wellbore includes running a cement retainer and a radially expanded perforating assembly into a wellbore on a run-in string. After the cement retainer is set, a firing head is actuated to cause the perforating gun to discharge. After perforations are formed, cement is introduced from the cement retainer into the isolated area and squeezed through the perforations. Thereafter, the run-in string disengages from the cement retainer leaving behind the plug formed. In yet another aspect, a firing head capable of being actuated by different means is used to discharge the perforating assembly.
摘要翻译：本发明提供一种以跳闸保存方式堵塞井筒的方法和装置。在一个方面，本发明包括设置在输入线上的水泥保持器和设置在水泥保持器下方的径向扩张的穿孔组件。在单次运行中，该装置用于穿孔井眼，并通过穿孔挤压水泥并进入周围的地层。在另一方面，一种堵塞井筒的方法包括将水泥保持器和径向膨胀的穿孔组件运行到入射柱中的井筒中。在水泥固定器固定之后，致动一个击发头使射孔枪放电。在形成穿孔之后，将水泥从水泥保持器引入隔离区域并挤压通过穿孔。此后，导入柱离开水泥固定器，留下形成的塞子。在另一方面，能够通过不同的装置致动的击发头被用于排出穿孔组件。

摘要： A perforating gun is supported from the lower end of a side pocket mandrel. The perforating gun includes a mechanical detonator which is received within the side pocket receptacle bore. The mechanical detonator is actuated in response to striking engagement by a kickover tool. The side pocket mandrel includes a longitudinal production bore which is connected in alignment with a string of production tubing. The perforating gun assembly is run in with the production tubing during initial installation of isolation packers, and the shoot is carried out while the well bore is in an underbalanced pressure condition.

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.
