Abstract
In the representative embodiment of the present invention disclosed herein, this new and improved perforating apparatus includes a plurality of encapsulated shaped explosive charges having their forward ends respectively fitted and threadedly secured in a facing relationship along the concave rear face of an elongated steel carrier strip of a unique design having its forward face complementally shaped for accommodation within a given size of well bore piping thereby allowing the largest possible mass of explosive to be disposed in each capsule. To assure the proper installation of the detonating cord, the rear portions of the two-part charge capsules are cooperatively arranged in a unique fashion so as to be rotatably positionable in relation to their forward portions for facilitating proper alignment of transversely-oriented cord-receiving openings provided in the base of each capsule.
