Abstract
A shaped charge for generating a large hole in material such as well casing downhole in a wellbore. A shaped charge liner is oriented about a longitudinal axis, and a disk is positioned at the liner apex. When an explosive material is initiated the liner collapses into a perforating jet. The disk alters the jet formation process and changes the shape and location of a bulge within the perforating jet. Consequently, the shape of the perforating jet retains a larger diameter for generating a larger hole in the material to be perforated or for controlling the penetration depth. The disk surfaces can be flat, concave, convex or other shapes, and the disk composition can be varied to accomplish different design criteria.
