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 ballistic interrupter adapted to accommodate one of a detonating cord or a detonator;
- and
- a detonation housing adapted to accommodate the ballistic interrupter and the other one of the detonating cord or the detonator so that the ballistic interrupter is actuable from:
- a disarmed state or configuration, in which the ballistic interrupter is rotationally oriented so as to provide a mechanical barrier impeding ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the detonation housing;
- and
- the other one of the detonating cord or the detonator accommodated within the detonation housing;
- to
- an armed state or configuration, in which the ballistic interrupter is rotationally oriented so as to permit ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the detonation housing;
- and
- the other one of the detonating cord or the detonator accommodated within the detonation housing;
- wherein the ballistic interrupter comprises an exterior surface and a first bore adapted to accommodate the one of the detonating cord or the detonator.
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 detonating cord or a detonator so that the ballistic interrupter is actuable from:
- a disarmed state or configuration, in which the ballistic interrupter is rotationally oriented so as to provide a mechanical barrier impeding ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the first bore of the ballistic interrupter;
- and
- the other one of the detonating cord or the detonator;
- to
- an armed state or configuration, in which the ballistic interrupter is rotationally oriented so as to permit ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the first bore of the ballistic interrupter;
- and
- the other one of the detonating cord or the detonator.
A detonation housing for a perforating gun, the detonation housing comprising:
- a body portion;
- and
- 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 detonating cord or a detonator;
- and
- a second bore defined by the body portion and adapted to accommodate the other one of the detonating cord or the detonator so that the ballistic interrupter is actuable from:
- a disarmed state or configuration, in which the ballistic interrupter is rotationally oriented so as to provide a mechanical barrier impeding ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the first bore of the detonation housing;
- and
- the other one of the detonating cord or the detonator accommodated within the second bore of the detonation housing;
- to
- an armed state or configuration, in which the ballistic interrupter is rotationally oriented so as to permit ballistic communication between:
- the one of the detonating cord or the detonator accommodated within the ballistic interrupter, which ballistic interrupter is accommodated within the first bore of the detonation housing;
- and
- the other one of the detonating cord or the detonator accommodated within the second bore of the detonation housing.
