OILFIELD SIDE INITIATION BLOCK CONTAINING BOOSTER

摘要

An initiation block for connecting a detonator with a detonating cord may have a body having a first face opposing a second face; a first chamber extending between the opposing faces and through the body, the first chamber being formed by a first bore serially arranged with a second bore, the second bore being shaped to seat the detonator adjacent to the second face; a second chamber extending between the opposing faces and through the body, the second chamber being parallel with the first chamber, the second chamber shaped complementary to the detonating cord; a passage providing communication between the first chamber and the second chamber; a booster positioned in the first bore and proximate to the first face, the booster positioned along the passage; and an opening formed in the body, the opening providing communication between an exterior of the body and a portion of the chamber between the booster and the detonator.

主权项

1. An apparatus for use in a wellbore, comprising:
a work string; a downhole tool conveyed by the work string, the downhole tool having a fluid tight interior, a detonating cord, and a detonator; and an initiation block disposed inside the fluid tight interior, the initiation block comprising a body having:
a first face;a second face opposing the first face;a first chamber extending between the opposing faces and through the body, the first chamber being formed by a first bore serially arranged with a second bore, the second bore seating the detonator adjacent to the second face;a second chamber extending between the opposing faces and through the body, the second chamber being parallel with the first chamber, the second chamber receiving the detonating cord;a passage formed in a wall separating the first chamber and the second chamber, the passage providing the only communication inside of the body between the first chamber and the second chamber;a booster positioned in the first bore and proximate to the first face, the booster positioned along the passage; andan opening formed in the body, the opening providing fluid communication between an exterior of the body and a portion of the first chamber between the booster and the detonator.
