US12753681 - Perforating gun and ballistic interrupter for same

A perforating gun used in oil and gas completions operations, the perforating gun including a ballistic interrupter actuable from a disarmed state or configuration, in which ballistic communication between a detonator and a detonation cord is impeded, to an armed state or configuration, in which ballistic communication between the detonator and the detonating cord is permitted. A gun string includes the perforating gun and one or more additional perforating guns substantially identical to the perforating gun.

The patent describes a perforating gun designed for oil and gas operations, featuring a ballistic interrupter that transitions between disarmed and armed states to control communication between a detonator and a detonating cord. This device allows for safe downhole detonation by providing a mechanical barrier in its disarmed state and enabling ballistic communication in its armed state.

Claim 1

1 . A perforating gun, comprising: a detonator; a detonating cord; and a ballistic interrupter actuable from: a disarmed state or configuration, in which: the ballistic interrupter is oriented so as to provide a mechanical barrier impeding ballistic communication between the detonator and the detonating cord; and the detonating cord is longitudinally overlapped by both the detonator and the mechanical barrier impeding said ballistic communication between the detonator and the detonating cord; to an armed state or configuration, in which: the ballistic interrupter is oriented so as to permit ballistic communication between the detonator and the detonating cord; and the perforating gun, including the detonator, the detonating cord, and the ballistic interrupter, is adapted to be run downhole for detonation; wherein the ballistic interrupter defines an exterior surface and a first bore adapted to accommodate one of the detonator or the detonating cord. a detonator; a detonating cord; and a ballistic interrupter actuable from: a disarmed state or configuration, in which: the ballistic interrupter is oriented so as to provide a mechanical barrier impeding ballistic communication between the detonator and the detonating cord; and the detonating cord is longitudinally overlapped by both the detonator and the mechanical barrier impeding said ballistic communication between the detonator and the detonating cord; to an armed state or configuration, in which: the ballistic interrupter is oriented so as to permit ballistic communication between the detonator and the detonating cord; and the perforating gun, including the detonator, the detonating cord, and the ballistic interrupter, is adapted to be run downhole for detonation; a disarmed state or configuration, in which: the ballistic interrupter is oriented so as to provide a mechanical barrier impeding ballistic communication between the detonator and the detonating cord; and the detonating cord is longitudinally overlapped by both the detonator and the mechanical barrier impeding said ballistic communication between the detonator and the detonating cord; the ballistic interrupter is oriented so as to provide a mechanical barrier impeding ballistic communication between the detonator and the detonating cord; and the detonating cord is longitudinally overlapped by both the detonator and the mechanical barrier impeding said ballistic communication between the detonator and the detonating cord; to an armed state or configuration, in which: the ballistic interrupter is oriented so as to permit ballistic communication between the detonator and the detonating cord; and the perforating gun, including the detonator, the detonating cord, and the ballistic interrupter, is adapted to be run downhole for detonation; the ballistic interrupter is oriented so as to permit ballistic communication between the detonator and the detonating cord; and the perforating gun, including the detonator, the detonating cord, and the ballistic interrupter, is adapted to be run downhole for detonation; wherein the ballistic interrupter defines an exterior surface and a first bore adapted to accommodate one of the detonator or the detonating cord.
