Adapter and shaped charge apparatus for optimized perforation jet

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.

What is claimed is: 
     
         1 . An adapter for a shaped charge comprising:
 a plurality of members configured to be secured to an inner surface of a shaped charge case; and   a securing mechanism, wherein   each member of the plurality of members is spaced apart from each other such that the adapter has a central open area, and   the securing mechanism is configured to secure the member to an inner surface feature of the shaped charge case.   
     
     
         2 . The adapter of  claim 1 , wherein each member of the plurality of members comprises:
 a first end; and   a second end opposite and spaced apart from the first end.   
     
     
         3 . The adapter of  claim 2 , wherein the securing mechanism extends from the second end of at least one of the members. 
     
     
         4 . The adapter of  claim 3 , wherein the securing mechanism extends from the at least one member in a direction away from the first end to engage the inner surface feature. 
     
     
         5 . The adapter of  claim 1 , wherein each member of the plurality of members comprises:
 a first surface; and   a second surface spaced apart from the first surface,   wherein the second surface is configured to be adjacent the inner surface of the shaped charge case.   
     
     
         6 . The adapter of  claim 5 , wherein the securing mechanism extends outwardly from the second surface of the member to engage the inner surface feature. 
     
     
         7 . The adapter of  claim 2 , wherein the securing mechanism extends from the first end of the member. 
     
     
         8 . The adapter of  claim 1 , wherein the securing mechanism comprises a protrusion configured for being received by one of a dimple, a hole and a slotted opening of the inner surface feature to secure the adapter in the shaped charge case. 
     
     
         9 . An adapter for a shaped charge, 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, wherein   the collar and the plurality of members are secured to an inner surface of a shaped charge case.   
     
     
         10 . The adapter of  claim 9 , 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.   
     
     
         11 . The adapter of  claim 10 , 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. 
     
     
         12 . The adapter of  claim 9 , 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. 
     
     
         13 . The adapter of  claim 9 , 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. 
     
     
         14 . The adapter of  claim 9 , wherein the adapter is formed from a plastic material.
