Abstract
A gun assembly for perforating wells comprising a plurality of guns with shape charges aligned centrically by end caps having insulated connector pins for conducting electrical signals and pressure through the end caps while preventing debris from the blast of one gun from entering and damaging the electrical connections and components of the next gun. The end caps being interconnected physically and electrically by specialized intermediate subs.
Claims17
A gun assembly for perforating wells comprising:
- at least one gun body casing, the casing being a hollow cylinder, with a box fitting at each end;
- a charge carrier, the carrier being a hollow cylinder, with exterior diameter less than the interior diameter of the casing, and a length shorter than the distance between the box fittings of the casing;
- a plurality of shape charges positioned radially inside the charge carrier and inter connected by a detonator cord;
- a plurality of end caps affixed to the ends of the carrier and axially aligning the carrier within the casing between the box fitting ends, and secured therein;
- at least one end cap being of a durable material, electrically conductive and electrically connects the charge carrier of the gun body;
- an addressable detonation switch electrically connected between an inner side of at least one end cap and the plurality of shape charges within the charge carrier.
