Abstract

A perforating gun system includes a cylindrical outer housing, a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly includes a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier, and a detonator holder incorporated into the first endplate of the charge carrier assembly and including a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive a detonator configured to detonate the one or more shaped charged in response to receiving a signal.

First claim

What is claimed is:

1. A perforating gun system, comprising:
a cylindrical outer housing;
a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charge carrier defining an interior configured to at least partially receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier; and
a detonator holder incorporated into the first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive a detonator whereby the detonator is at least partially received in the interior of the charge carrier and is configured to detonate the one or more shaped charges in response to receiving a signal.

2. The perforating gun system of claim 1 , wherein the detonator holder comprises one or more lateral openings that extend entirely through the detonator holder, and wherein the one or more lateral openings are positioned laterally adjacent to the second passage.

3. The perforating gun system of claim 2 , wherein the one or more lateral openings face away from the first passage.

4. The perforating gun system of claim 1 , wherein the first endplate defines an annular face extending around a central axis of the perforating gun system, and wherein one of the pair of longitudinal ends of the detonator holder couples with the annular face of the first endplate.

5. The perforating gun system of claim 1 , further comprising a switch configured to detonate the detonator in response to receiving a firing signal, wherein the first endplate defines a switch receptacle for receiving the switch.

6. A perforating gun system, comprising:
a cylindrical outer housing;
a charger carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier; and
a detonator holder incorporated into the first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive a detonator configured to detonate the one or more shaped charges in response to receiving a signal;
wherein the detonator holder further comprises a first interrupter opening and a second interrupter opening positioned opposite the first interrupter opening, and wherein the first interrupter opening and the second interrupter opening are configured to slidably receive an interrupter to block a ballistic signal between the first passage and the second passage.

7. A perforating gun system, comprising:
a cylindrical outer housing;
a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier; and
a detonator holder incorporated into the first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive a detonator configured to detonate the one or more shaped charges in response to receiving a signal;
wherein the detonator holder comprises one or more openings that extend entirely through the detonator holder, and wherein the one or more openings are positioned adjacent to the second passage.

8. A perforating gun system, comprising:
a cylindrical outer housing;
a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier; and
a detonator holder formed monolithically with first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage configured to receive a detonating cord, and a second passage configured to receive a detonator configured to detonate the one or more shaped charges in response to receiving a signal.

9. The perforating gun system of claim 8 , wherein the detonator holder comprises one or more lateral openings that extend entirely through the detonator holder, and wherein the one or more lateral openings are positioned laterally adjacent to the second passage.

10. The perforating gun system of claim 9 , wherein the one or more lateral openings face away from the first passage.

11. The perforating gun system of claim 8 , wherein the first endplate defines an annular face extending around a central axis of the perforating gun system, and wherein one of the pair of longitudinal ends of the detonator holder couples with the annular face of the first endplate.

12. The perforating gun system of claim 8 , further comprising a switch configured to detonate the detonator in response to receiving a firing signal, wherein the first endplate defines a switch receptacle for receiving the switch.

13. A perforating gun system, comprising:
a cylindrical outer housing;
a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charger carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier; and
a detonator holder formed monolithically with first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage configured to receive a detonating cord, and a second passage configured to receive a detonator configured to detonate the one or more shaped charges in response to receiving a signal;
wherein the detonator holder further comprises a first interrupter opening and a second interrupter opening positioned opposite the first interrupter opening, and wherein the first interrupter opening and the second interrupter opening are configured to slidably receive an interrupter to block a ballistic signal between the first passage and the second passage.

14. A perforating gun system, comprising:
a cylindrical outer housing;
a charge carrier assembly receivable in the outer hosing, wherein the charge carrier assembly comprises a charge carrier configured to receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier, and
a detonator holder formed monolithically with first endplate of the charge carrier assembly and comprising a pair of opposed longitudinal ends, a first passage configured to receive a detonating cord, and a second passage configured to receive a detonator configured to detonate the one or more shaped charged in response to receiving a signal;
wherein the detonator holder comprises one or more openings that extend
