An apparatus and method for providing a fiber optic cord in a perforating gun.

An apparatus and method for providing a fiber optic cord in a perforating gun.

The present disclosure is an explosive matrix assembly that has a first single detonating cord formed into a first grid, and the first grid has a first plurality of detonating cord portions lying in a first plane and a second plurality of detonating cord portions lying in a second plane and the first plurality of detonating cord portions perpendicularly overlay the second plurality of detonating portions. Additionally, the matrix assembly has a second single detonating cord formed into a second grid, and the second grid has a third plurality of detonating cord portions lying in a third plane and a fourth plurality of detonating cord portions lying in a fourth plane and the third plurality of detonating cord portions perpendicularly overlay the fourth plurality of detonating portions. Further, the matrix assembly has a third single detonating cord formed into a third grid, and the third grid has a fifth plurality of detonating cord portions lying in a fifth plane and a sixth plurality of detonating cord portions lying in a sixth plane and the fifth plurality of detonating cord portions perpendicularly overlay the sixth plurality of detonating portions. The matrix assembly also has a first fastener coupling the first grid perpendicular to the second grid, a second fastener coupling the first grid perpendicular to the third grid, and a third fastener coupling the second grid perpendicular to the third grid thereby forming a partial cube.

A perforating tool includes an encapsulated shaped charge that has a bulkhead with a reduced wall thickness section, a plate having a shallow recess, and a detonating cord having an energetic core. The energetic core forms the plate into an explosively formed perforator when detonated. The plate is positioned to direct the explosively formed perforator into the reduced wall thickness section.

A perforating gun includes a charge tube disposed inside a carrier and a plurality of sets of shaped charges axially distributed along the charge tube and the initiation tube. Each shaped charge of the plurality of shaped charges is supported at an opening in the charge tube. The perforating gun also includes a plurality of detonator cords. Each detonator cord of the plurality of detonator cords connects to one shaped charge in each set of shaped charges.
