Abstract

A method and apparatus for containing one or more shaped charges in a single plane, using a shaped charge housing containing a cluster of one or more shaped charges. The cluster contains with the apex ends facing each other, arrayed about the center axis of a gun body, and detonated from a single initiator located in the middle of the cluster of the one or more shaped charges. The shaped charge housing can be one of many shaped charge housings coupled together to perforate in a plurality of single planes.

First claim

What is claimed is:

1. A perforating gun assembly comprising:
a first cylindrical body composed of an electrical insulator having a plurality of orthogonal hollow cutouts in a first orthogonal perforation plane, the plurality of hollow cutouts further containing a plurality of shaped charges, one shaped charge disposed in each cutout;
a first detonator disposed within a center portion of the cylindrical body, wherein the shaped charges perforate in the first orthogonal plane when detonated by the first detonator;
a threaded cylindrical interface at a protruding distal end of the first cylindrical body wherein the threaded cylindrical interface has a common center axis and includes a thru hole located therethrough;
a contact retainer nut coupled to the threaded cylindrical interface; and
a contact pin, having a substantially cylindrical shaped body and disposed partially within the thru hole, protruding from the threaded cylindrical interface, and restrained by the retainer nut.

2. The perforating gun assembly of claim 1 further comprising the first cylindrical body having a first cylindrical portion having a center axis with an outer surface, a protruding distal end having a first thru hole, a conical shaped end having a second thru hole, and at least one first half shaped charge receptacle.

3. The perforating gun assembly of claim 2 further comprising a second cylindrical portion along the center axis and proximate to the first cylindrical portion, having a second outer surface, a thru hole, and a conical shaped end, and at least one second half shaped charge receptacle.

4. The perforating gun assembly of claim 1 further comprising a spring located within the thru hole and loading the contact pin against the retainer nut.

5. The perforating gun assembly of claim 4 further comprising a contact strap passing over the first cylindrical body and a second cylindrical body and coupling to the spring disposed within the thru hole and a conical shaped end of the second cylindrical body.

6. The perforating gun assembly of claim 1 further comprising a booster holder, having a substantially cylindrical shaped body and disposed partially within a second thru hole of a second cylindrical body.

7. The perforating gun assembly of claim 1 wherein the plurality of shaped charges is arrayed about a center axis of the first cylindrical body.

8. The perforating gun assembly of claim 1 wherein at least one shaped charge is adapted to perforate in a plane orthogonal to a center axis of the first cylindrical body.

9. The perforating gun assembly of claim 1 further comprising:
a second cylindrical body composed of an electrical insulator having a plurality of orthogonal hollow cutouts in a second orthogonal perforation plane, the plurality of hollow cutouts further containing a plurality of shaped chares, one shaped charge disposed in each cutout, wherein the second cylindrical body is located adjacent to and coaxial with the first cylindrical body; and
a second detonator disposed within a center of the second cylindrical body, wherein the shaped charges perforate in the second orthogonal plane when detonated by the second detonator.

10. The perforating gun assembly of claim 1 , wherein the first detonator further comprises an addressable switch.

11. The perforating gun assembly of claim 1 , wherein the plurality of shaped charges is detonated simultaneously by the first detonator.

12. The perforating gun assembly of claim 1 , wherein the first detonator further comprises a percussion initiator.

13. The perforating gun assembly of claim 1 , wherein the first detonator is coupled to a booster located proximate to the plurality of shaped charges.

14. A perforating gun assembly comprising:
a first cylindrical body composed of an electrical insulator having a plurality of orthogonal hollow cutouts in a first orthogonal perforation plane, the plurality of hollow cutouts further containing a plurality of shaped charges, one shaped charge disposed in each cutout;
a first detonator disposed within a center portion of the cylindrical body, wherein the shaped charges perforate in the first orthogonal plane when detonated by the first detonator;
a threaded cylindrical interface at a protruding distal end of the first cylindrical body wherein the threaded cylindrical interface has a common center axis and includes a thru hole located therethrough;
a contact retainer nut coupled to the threaded cylindrical interface;
a contact pin, having a substantially cylindrical shaped body and disposed partially within the thru hole, protruding from the threaded cylindrical interface, and restrained by the retainer nut; and
a spring located within the thru hole and loading the contact pin against the retainer nut.

15. The perforating gun assembly of claim 14 further comprising the first cylindrical body having a first cylindrical portion having a center axis with an outer surface, a protruding distal end having a first thru hole, a conical shaped end having a second thru hole, and at least one first half shaped charge receptacle.

16. The perforating gun assembly of claim 14 further comprising a contact strap passing over the first cylindrical body and a second cylindrical body and coupling to the spring disposed within the thru hole and a conical shaped end of the second cylindrical body.

17. The perforating gun assembly of claim 14 further comprising a booster holder, having a substantially cylindrical shaped body and disposed partially within a second thru hole of a second cylindrical body.

18. The perforating gun assembly of claim 14 wherein the plurality of shaped charges is arrayed about a center axis of the first cylindrical body.

19. The perforating gun assembly of claim 14 wherein at least one shaped charge is adapted to perforate in a plane orthogonal to a center axis of the first cylindrical body.

20. A perforating gun assembly comprising:
