Abstract

Components for a perforation gun system are provided including combinations of components including a self-centralizing charge holder system and a bottom connector that can double as a spacer. Any number of spacers can be used with any number of holders for any desired specific metric or imperial shot density, phase and length gun system.

First claim

What is claimed is:

1. A stackable charge holder for a perforation gun system having an outer gun carrier, the charge holder comprising:
a charge receiving structure configured for receiving a shaped charge, the structure comprising a pair of arms extending between a first rotation coupling and a second rotation coupling; and
a plurality of projections extending from each of the arms of the charge receiving structure, wherein the plurality of projections are configured for centralizing the shaped charge within the gun carrier.

2. The stackable charge holder of claim 1 , wherein a pair of the plurality of projections is configured for capturing a detonation cord traversing the charge holder.

3. The stackable charge holder according to claim 1 , wherein the first rotation coupling and the second rotation coupling being configured for providing a selectable clocking rotation between the charge holder and other components of the perforation gun system.

4. The stackable charge holder according to claim 3 , wherein the first rotation coupling comprises a plurality of pins symmetrically arranged about a central axis of one side of the first rotation coupling, and the second rotation coupling comprises a plurality of sockets symmetrically arranged about the central axis of the second rotation coupling.

5. The stackable charge holder of claim 1 , wherein the plurality of projections are also configured for retaining the shaped charge.

6. The stackable charge holder of claim 1 , wherein the charge receiving structure is injection molded.
