摘要： An apparatus (100) for selectively firing a perforating gun having a plurality of gun assemblies (110,112) may include an end plate (202), a portion of a signal communication circuit (116), an initiator assembly, and an initiating element. The end plate has a cavity (206) formed by at least a first passage intersecting a second passage. The first passage (230) extends from a planar end face of the end plate and the second passage (232) extends from a circumferential surface of the end plate. The portion of a signal communication circuit is disposed in the end plate and conveys signals between the first gun and the second gun. The initiator assembly is at least partially disposed in the first passage. The initiating element (248) is sized to pass through the second passage. The initiating element is also configured to electrically couple to the portion of the signal communication circuit and to thermally couple to the initiator assembly when at least partially seated in the first passage.

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 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.

摘要： A well tool (60) includes a perforating gun (108), a sealing element (130), at least one pressure sensor (150), a detector (132), a controller (152), and an anchor (134). The perforating gun (108) perforates the wellbore tubular in response to a firing signal. The sealing element (130) is connected to the perforating gun (108) and generates a pressure differential thereacross. The at least one pressure sensor (150) is associated with the sealing element (130) and detects a surface transmitted pressure signal. The detector (132) detects at least one marker (70) positioned along the wellbore (12) and which includes a perforating marker (70) associated with a perforating depth. The controller (152) is in signal communication with the at least one pressure sensor (150) and the detector (132) and is configured to transmit the firing signal to the perforating gun (108) only after: (i) the at least one pressure sensor (150) detects the surface transmitted pressure signal, and (ii) the detector (132) detects the perforating marker (70). The anchor (134) is connected to the perforating gun (108) and selectively locks the perforating gun (108) to the wellbore tubular.

摘要： An interrupter for use with a wellbore tool may include a housing having an interior and a fusible body disposed in the housing interior. The fusible body may be solid below a specified temperature and liquid above the specified temperature. The fusible body communicates a first high-order detonation to a detonator only when liquid. The communicated the first high-order detonation is at a magnitude sufficient to cause the detonator to produce a second high-order detonation.
