US12584386 - Perforating gun with detonation module

An apparatus for selectively firing a perforating gun having a plurality of gun assemblies may include an end plate, a portion of a signal communication circuit, an initiator assembly, and an initiating element. The end plate has a cavity formed by at least a first passage intersecting a second passage. The first passage extends from a planar end face of the end plate and the second passage extends from a circumferential surface of the end plate. The portion of a signal communication circuit is disposed in the end plate and conveys signals between the first gun and the second gun. The initiator assembly is at least partially disposed in the first passage. The initiating element is sized to pass through the second passage. The initiating element is also configured to electrically couple to the portion of the signal communication circuit and to thermally couple to the initiator assembly when at least partially seated in the first passage.

The patent describes an apparatus for selectively firing a perforating gun with multiple gun assemblies, featuring an end plate with intersecting passages that house a signal communication circuit and an initiator assembly. The design allows for the electrical and thermal coupling of an initiating element to facilitate the operation of the gun assemblies.

Claim 1

1 . An apparatus for selectively firing a perforating gun having a plurality of gun assemblies, the plurality of gun assemblies including at least a first gun and a second gun, the apparatus comprising: an end plate having a cavity formed by at least a first passage intersecting a second passage, the first passage extending from a planar end face of the end plate and the second passage extending from a circumferential surface of the end plate; a portion of a signal communication circuit disposed in the end plate, the signal communication circuit conveying signals between the first gun and the second gun; a body disposed at least partially in the second passage; an initiator assembly at least partially disposed in the first passage; and an initiating element projecting from the body, the initiating element configured to electrically couple to the portion of the signal communication circuit and thermally couple to the initiator assembly when at least partially seated in the first passage. an end plate having a cavity formed by at least a first passage intersecting a second passage, the first passage extending from a planar end face of the end plate and the second passage extending from a circumferential surface of the end plate; a portion of a signal communication circuit disposed in the end plate, the signal communication circuit conveying signals between the first gun and the second gun; a body disposed at least partially in the second passage; an initiator assembly at least partially disposed in the first passage; and an initiating element projecting from the body, the initiating element configured to electrically couple to the portion of the signal communication circuit and thermally couple to the initiator assembly when at least partially seated in the first passage.
