Abstract
A method and system for a perforating gun having a box by pin perforating gun system using swaged down gun bodies. The box by pin perforating gun system may include a removable cartridge to hold a detonator with a switch and an insulated charge holder as an electrical feed-through.
Claims22
A perforating gun system comprising:
- a first gun body having external threads at a first end, internal threads at a second end, shaped charges arrayed within a loading tube located within, a detonating cord coupled to the shaped charges;
- a cartridge inserted in the gun body containing an electrically actuated detonator adjacent to the detonating cord, a shunt, and an electrical switch for selective detonation, wherein the shunt is electrically coupled to the electrical switch, which is further electrically coupled to the detonator, wherein the insertable cartridge can selectively fire the perforating charges in the first gun body, independent of any additional gun body coupled to the first gun body;
- and
- a contact wave spring and a deto transfer puck, wherein the contact wave spring is engaged between the insertable cartridge and the deto transfer puck.
