Abstract
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.
Claims29
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 ballistic interrupter for a perforating gun, the ballistic interrupter comprising:
- an elongated body defining an exterior surface;
- and
- a first bore formed in the elongated body and adapted to accommodate one of a detonator or a detonating cord so that the ballistic interrupter is 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 detonation housing for a perforating gun, the detonation housing comprising:
- a body portion;
- a first bore defined by the body portion and adapted to accommodate a ballistic interrupter, which ballistic interrupter is adapted to accommodate one of a detonator or a detonating cord;
- and
- a second bore defined by the body portion and adapted to accommodate the other one of the detonator or the detonating cord so that the ballistic interrupter is 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.
