The invention provides a subterranean well casing perforating gun device which employs shaped explosive charges to perforate the well casing. The device generally defines an outer tubular housing assembly concentrically insertable in the well and defining a vertical axis, cylindrical chamber. A tubular carrier of polygonal cross sectional configuration is insertable in the chamber in concentric relationship to the cylindrical wall of the cylindrical chamber. Each of the faces of the carrier have a plurality of spaced passages therethrough, each passage having a configuration substantially corresponding to the configuration of the polygonal face. A shaped charge container has its cylindrical body insertable in any selected one of the passages and a radial flange on the outer end for abutting the polygonal face portion adjacent the respective passage, thereby limiting the insertion of each of the containers into the selected passage. Selectively disengageable fastening means are operable from the exterior of the carrier for clamping the radial flange against the respective polygonal face and for selective disengagement therefrom from the exterior of the carrier. The invention also contemplates a method of utilization of the carrier and the gun, as well as to incorporation of same into a particular perforating and gravel packing method and apparatus.
