Abstract

Claims (20)

1. 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.

2. The shaped charge of claim 1 , wherein the plurality of members comprises:

a first member; and

a second member,

wherein the first and second members are spaced 180 degrees from each other on the collar.

3. The shaped charge of claim 2 , wherein a width of each of the first member and the second member spans between approximately 20 degrees to 100 degrees of a circumference of the collar.

4. The shaped charge of claim 1 , wherein each of the plurality of members comprise a first end and a second end opposite and spaced apart from the first end, wherein the collar is secured to a substantially central portion of each of the members between the first and second ends.

5. The shaped charge of claim 4 , wherein, in each member of the plurality of members, a thickness of the first end is less than a thickness of the corresponding substantially central portion.

6. The adapter of claim 4 , wherein, in each member of the plurality of members, a thickness of the second end is less than a thickness of the corresponding substantially central portion.

7. The adapter of claim 4 , wherein, in each member of the plurality of members, a thickness of the substantially central portion is greater than a thickness of the first end and greater than a thickness of the second end.

8. The shaped charge of claim 1 , wherein a surface profile of each of the plurality of members is contoured to conform to a contour of the inner surface of the shaped charge case.

9. The shaped charge of claim 1 , wherein the adapter is formed from a plastic material.
