摘要： A non-linear shaped charge perforator for use in perforating an oil and gas formation into which a wellbore has been drilled comprises a monolithic, axisymmetric metal case in which is disposed a main explosive charge between the front of the case, which is closed with a concave metal liner, and the closed back end of the case. The main explosive charge contains multiple initiation points, preferably two initiation points located about 180° apart on the outside surface of the charge, so that when the perforator is detonated the main charge is initiated such that the metal liner is collapsed into a non-circular jet, preferably a fan-shaped jet, that pierces the casing of the wellbore and forms non-circular perforations, preferably slot-shaped perforations, in the surrounding formation.

摘要： The improved perforation gun of the present invention includes an outer gun barrel, which is used in conjunction with an inner movable charge carrier or an inner movable sleeve to trap virtually all of the debris created by the firing of the perforation gun. This elimination of debris reduces costly operational problems in both gravel pack and horizontal well completions. It also improves the production from a perforated underground hydrocarbon bearing formation since there is no debris to potentially cause plugging in the well or subsequent production lines.
摘要翻译：本发明的改进的穿孔枪包括外枪管，其与内部可移动电荷载体或内部可移动套管结合使用，以捕获几乎所有由射孔枪射击产生的碎屑。这种消除碎屑减少了砾石充填和水平井完井中的昂贵的操作问题。它还改善了穿孔地下含烃地层的生产，因为没有碎屑可能导致井或其后的生产线堵塞。

摘要： A shaped charge is formed having a pressed polymer pellet positioned between the explosive charge and the metal liner. The shock wave resulting from detonation of the explosive passes through the polymer to the liner. The collapse of the liner results in the formations of a jet—piercing the casing. The high-pressure gaseous by-products of the explosive force (inject) the polymer in the perforation “tunnel”. This shockwave will also start the decomposition of the polymer. The polymer will continue to decompose during its injection into the tunnel. As it is being injected into the perforation tunnel, the residue heat generated by the explosive combined with the shear and induced plastic flow, the polymer will ignite and burn. The burn time will be an order of magnitude greater than the explosive; the pressure generated by the polymer will be an order of magnitude less than the explosive.

摘要： An apparatus for stimulating a subterranean formation includes a first tube, a second tube, a combustion body and an ignition propagator. The second tube is positioned within the first tube interior and the second tube interior is sealed from the first tube interior to substantially prevent fluid communication between the first tube interior and the second tube interior. The combustion body is formed from a solid propellant and is positioned within the first tube interior external to the second tube interior. The ignition propagator is positioned within the second tube interior and is substantially free from fluid contact with fluid residing in the surrounding environment external to the first tube wall.

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.
