Abstract
An adapter for a shaped charge includes a plurality of members configured to be secured to an inner surface of a shaped charge case. Each member of the plurality of members is spaced apart from each other such that the adapter has a central open area. According to an aspect, a securing mechanism is configured to secure the member to an inner surface feature of the shaped charge case.
Claims9
A shaped charge comprising:
- a shaped charge case comprising an inner surface and an outer surface, wherein the inner surface defines a hollow interior of the shaped charge case;
- an adapter coupled to the inner surface of the shaped charge case, the adapter comprising:
- a collar;
- and
- a plurality of members secured to the collar in a spaced apart configuration from each other such that the adapter has a central open area;
- an explosive load disposed within the hollow interior atop the adapter, such that the explosive load covers the adapter and is in direct contact with a portion of the inner surface of the shaped charge case;
- and
- a liner disposed adjacent the explosive load, wherein
- at least a portion of the adapter displaces some of the explosive load, and
- the displaced explosive load is configured to accelerate the liner to produce a perforating jet upon detonation of the shaped charge such that the adapter is configured to produce an atypical perforation hole geometry in a target.
