Abstract
A loaded perforating gun and/or downhole perforating tool are assembled and used for perforating a wellbore. The loaded perforating gun includes a gun housing, a detonator assembly, and a plunging charge assembly. The plunging charge assembly includes a charge tube, a shaped charge, and a plunger. The plunger includes a receiving cap, and a detonator cord supported in the receiving cap. The shaped charge is operatively connected to the detonator cord. The detonator is selectively connected to the detonator cord by the plunger. The plunging charge assembly is movable between a disarmed position with the detonator cord disconnected from the detonator assembly and an armed position with the detonator cord operatively connected to the detonator assembly whereby, when the detonator can selectively pass a detonation signal via the detonator cord to the shaped charges.
