摘要： A firing head for selectively activating an initiator of a downhole tool may include a housing, a pin, and a moveable stopper. The housing may have a bore and a radially enlarged chamber formed along the bore. The pin is disposed in the bore and has a circumferential groove formed on an outer surface of the shank. The moveable stopper is disposed in the radially enlarged chamber. The stopper is only partially disposed in the groove when the housing is in a vertical position. The stopper moves out of the groove when the housing has a predetermined minimum angular deviation from the vertical position.

摘要： An apparatus for selectively isolating a firing head associated with a perforating gun may include an igniter coupled to a firing head, a time delay module coupled to the igniter and generating a pressure pulse after being activated by the igniter, a metering module, and a second firing head. The metering module may be coupled to the time delay module and including a housing having a bore and at least one opening exposed to a wellbore annulus. A piston disposed in the housing bore may have at least one passage. The piston is axially displaced from a first position to a second position by the generated pressure pulse. The second firing head is coupled to the metering module and is in fluid communication with the housing bore. The piston blocks fluid communication from the at least one opening of the housing and the second firing head in a first position and allows fluid communication from the at least one opening of the housing to the second firing head in the second position.

摘要： A method for perforating a subterranean formation includes positioning a shaped charge and a reactant composite material in a carrier; positioning the carrier in the wellbore; detonating the shaped charge; and disintegrating the reactant composite material using a shock generated by the detonated shaped charge. The method may also include initiating a first deflagration by using carbon and heat resulting from the detonation of the shaped charge and an oxygen component of the disintegrated reactant composite material. A system for performing the method may include a carrier, a shaped charge positioned in the carrier; and a reactant composite material positioned in the carrier. The reactant composite material may be configured to disintegrate upon detonation of the shaped charge.

摘要： A perforating system has a perforating module comprising a unitary body of explosive. The explosive is contained within a non-explosive casing, or liner, having formed indentations and a cover thereover. The indentations, which will transform into explosively formed penetrators (EFP's) upon detonation, have a perimeter shape that allows for improved packing density, e.g., a hexagonal perimeter, which results in relatively little "dead space" wherein no perforating penetrators are generated. In operation, the module provides a relatively dense shot pattern and substantially reduced amount of post-detonation debris that could clog the perforations and/or require remedial clean-up or repeat perforation.

摘要： A carrier tube for use in a wellbore perforating gun has inner and outer layers selected from materials of different, comparative physical properties. The inner layer has a higher compressive strength, and the outer layer has a higher yield strength. The inner layer enables the tube to withstand wellbore compressive pressures, which may, depending upon the material selected, include relatively high pressures, while the outer layer contains any fragments of the inner layer that result upon detonation of the gun. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： The present invention provides systems, methods and devices for selectively firing a gun train formed of a plurality of guns. Conventionally, the guns each include a detonator assembly that detonates upon receiving a firing signal transmitted by a surface source. In one embodiment of the present invention, an operator provided in the gun train selectively couples one or more of the guns to the signal transmission medium. The operator has an safe state wherein the operator isolates the gun from the firing signal and an armed state wherein the operator enable the transmission of the firing signal to the gun. A control signal is used to move operator between the safe state and the armed state. In some embodiments, two or more guns are each provided with a separate operator. In other embodiments, one operator can selectively engage two or more guns.

摘要： An apparatus for perforating a wellbore includes a plurality of perforator units that includes a first perforator unit and a second perforator unit; and a signal transfer module connecting the first perforator unit to the second perforator unit. The signal transfer module includes an enclosure having a bore, an input end, and an output end, an initiator positioned adjacent to the first perforator unit and at least partially in the enclosure, an initiator, an igniter, a fuse, and an isolator. The initiator generates a shock wave when initiated. The igniter is positioned in the enclosure and generates a low order output upon receiving the shock wave generated by the initiator. The fuse is positioned in the enclosure and is initiated by the low order output of the igniter. The fuse outputs a high order output from the output end of the enclosure. The isolator secures the fuse body in the bore of the enclosure. The isolator includes a shock attenuator. Only the shock attenuator physically connects the fuse to the enclosure.
