Tubing conveyed perforating gun electrical detonator

摘要

For use with a tubing conveyed perforating gun assembly, a wireline manipulated electrically actuated detonator assembly traversing the interior of the tubing is described. In the preferred and illustrated embodiment, a wireline connected with a sinker bar supports the detonator assembly having a sinker bar sub terminating in a taper adjacent to a set of deflectable collet fingers comprising a latch assembly. The collet fingers are deflected outwardly by the tapered surface and are forced into an undercut located above a booster and detonating cord affixed to the tubing conveyed perforating gun assembly for firing the perforating guns.
