Abstract
An oil shaped charge for deeper penetration includes a case, a quantity of explosive material, and a liner. The case is designed with different inner surface sections, where the step inner surface section creates maximum space for the explosive material so that the explosive material can be effectively placed between the case and the liner. A step conical region of the liner, a step conical inner surface of the case, and an effective placement of the explosive material are able to achieve significantly higher speeds for liner materials flow into the jet, thus creating deeper penetration.
