Abstract

The disclosed embodiments include bulkheads for perforating guns and perforating gun assemblies. A bulkhead includes a threadless exterior surface that spans a length of a threaded connection of adjacent first and second perforating guns. The bulkhead also includes a first exterior groove having a first sealing element partially disposed in the first exterior groove. The bulkhead further includes a second exterior groove having a second sealing element partially disposed in the second exterior groove, where the first sealing element and the second sealing element are positioned around the threaded connection.

Claims (33)

1. A bulkhead for a perforating gun, comprising:

a threadless exterior surface that spans an entire length of a threaded connection of adjacent first and second perforating guns;

a first exterior groove having a first sealing element partially disposed in the first exterior groove; and

a second exterior groove having a second sealing element partially disposed in the second exterior groove;

an interior pass through that houses one or more components of a perforating gun assembly within the bulkhead

an electrical sealing element disposed within the interior pass through; and

a compressible retainer, wherein compression of the compressible retainer pressure seals the one or more components of the perforating gun assembly,

wherein the threaded connection is positioned in between the first sealing element and the second sealing element.

2. The bulkhead of claim 1 , further comprising a notch positioned between the first perforating gun and the second perforating gun.

3. The bulkhead of claim 2 , wherein the notch comprises an angled surface.

4. The bulkhead of claim 3 , wherein the angled surface is disposed on a first side of the notch, and wherein the notch comprises a second angled surface that is disposed on a second side that is opposite of the first side.

5. The bulkhead of claim 1 , further comprising an alignment piece disposed on the exterior surface.

6. The bulkhead of claim 1 , wherein the interior pass through comprises a threaded surface that fastens the one or more components of the perforating gun assembly to the bulkhead.

7. The bulkhead of claim 1 , wherein the first sealing element is completely disposed within the first exterior groove, and wherein the second sealing element is completely disposed within the second exterior groove.

8. The bulkhead of claim 1 , further comprising an electrical ground.

9. The bulkhead of claim 1 , wherein the bulkhead is fitted inside a gun body of a perforating gun assembly.

10. A perforating gun assembly, comprising:

a first perforating gun;

a second perforating gun; and

a bulkhead, comprising:

a threadless exterior surface that spans an entire of a threaded connection of the first perforating gun and the second perforating gun;

a first sealing element;

a second sealing element;

an interior pass through that houses one or more components of the perforating gun assembly within the bulkhead;

an electrical sealing element disposed within the interior pass through; and

a compressible retainer, wherein compression of the compressible retainer pressure seals the one or more components of the perforating gun assembly,

wherein the threaded connection is positioned in between the first sealing element and the second sealing element.

11. The perforating gun assembly of claim 10 , further comprising a notch positioned between the first perforating gun and the second perforating gun.

12. The perforating gun assembly of claim 11 , wherein the notch comprises an angled surface.

13. The perforating gun assembly of claim 12 , wherein the notch comprises a second angled surface, and wherein the angled surface is disposed on a first side of the notch and wherein the second angled surface is disposed on a second and opposite side of the notch.

14. The perforating gun assembly of claim 10 , further comprising an alignment piece disposed on the exterior surface.

15. The perforating gun assembly of claim 10 , wherein the interior pass through comprises a threaded surface that fastens the one or more components of the perforating gun assembly to the bulkhead.

16. The perforating gun assembly of claim 10 , wherein the bulkhead is partially housed inside a gun body of the perforating gun assembly.
