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 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： 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： 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.

摘要： The present invention presents a method and apparatus for perforating a well in response to fluid pressure in a first tubing string while establishing a pressure balance in response to pressure in a second string, or in the well casing, through which the well will be produced. Additionally, redundant firing heads may be provided for perforating guns utilized to assure optimal reliability of the system. One or more perforating equipment assemblies may be employed in a tool string, each of which includes redundant firing mechanisms responsive to pressure in the tool string. Additionally, a firing head assembly is utilized which is initially responsive to pressure in the tool string, but which is subsequently actuated by annulus pressure. The firing head is suitable for use with much lower annulus pressures than are utilized with conventional hydraulically actuated firing head assemblies.

摘要： A firing head actuator for a perforating gun includes an atmospheric pressure chamber which is run into the well on a slick line. The atmospheric pressure chamber can then be communicated with a low pressure side of an actuating piston to move the piston and initiate firing of the perforating guns. Either pyrotechnic or electrical time delays may be built in to the firing head actuator.

摘要： A method and apparatus for perforating oil well casing in a well bore, with particular advantage in highly deviated well bores. The perforating guns are run into the well bore using the production tubing. A sliding sleeve is connected in the tubing above the guns and a packer is run in for setting above the sliding sleeve and guns. The assembly is run into the well bore until the guns extend into the highly deviated portion of the bore where the well casing is to be perforated. The packer is set into place, isolating that portion of the well bore below the packer from that portion above the packer, and the sliding sleeve is opened using a wireline or other means. The well bore below the packer is pressurized through the tubing to ensure that the packer is properly set. The pressure is then allowed to bleed off and the sliding sleeve is closed. The guns use a differential pressure-actuated firing head which is actuated upon a predetermined differential pressure between the production tubing bore and the annulus between the tubing and the casing. The invention provides the capability of perforating well casing using relatively low values of actuating pressure, providing greater control over performating conditions such as underbalance.
摘要翻译：一种用于在井眼中穿孔油井套管的方法和装置，在高度偏离的井筒中特别有利。穿孔枪使用生产管道进入井筒。滑动套管连接在枪上方的管道中，并且封隔器被运行以设置在滑动套筒和枪上方。组件进入井眼，直到枪伸入井套孔穿孔的高偏差部分。将封隔器固定就位，将封隔器下方的井眼部分与封隔器上方的部分隔离，并使用电缆或其他方式打开滑套。封隔器下方的井眼通过管道加压，以确保封隔器正确固定。然后允许压力泄放并且滑动套筒关闭。枪支使用压差致动的点火头，其在生产油管孔与油管和套管之间的环空间之间的预定差压下被致动。本发明提供使用相对较低的致动压力值穿孔井壳的能力，从而对诸如不平衡的执行条件提供更大的控制。
