ABSTRACT:
A unique structure for the shaped charge allows the formation of a uniquely configured jet with an alternating velocity gradient along its length. In a preferred embodiment, the velocity of material within the jet is significantly greater at two points along its length than elsewhere. As a result, the material of the jet "bunches up" at these points, forming two bulges. The forwardmost bulge is expended as it breakes through the gun wall and travels through the borehole fluid. The second bulge grows as the jet traverses the annular space between the gun wall and the casing, providing a large diameter mass to impact the casing and form a large diameter hole therein.
