Abstract
A box by pin perforating gun system using swaged down gun bodies, a removable cartridge to hold a detonator and switch, and an insulated charge holder as an electrical feed-through.
Claims5
A perforating gun system comprising:
- a first gun body having external threads at a first end and internal threads at a second end;
- a cartridge holding a detonator;
- a shaped charge loading tube having an upper end and a lower end;
- an upper end fitting on the upper end of the shaped charge loading tube;
- a lower end fitting on the lower end of the shaped charge loading tube;
- an upper insulating cap on upper end fitting;
- a lower insulating cap on lower end fitting;
- wherein the upper and lower end fittings are conductive;
- wherein the cartridge has an electrical contact proximate to the detonator;
- and
- wherein the lower end of the loading tube has an electrical contact adapted to contact the electrical contact proximate to the detonator.
8 more elements
A perforating gun system comprising:
- a first gun body having external threads at a first end and internal threads at a second end;
- a cartridge holding a detonator;
- a switch electrically connected to the detonator;
- at least one insulator between the shaped charge loading tube and the gun body;
- wherein the cartridge has at least one electrical contact at each end;
- and
- wherein at least one of the electrical contacts of the cartridge is resiliently biased.
4 more elements
A perforating gun system comprising:
- a first gun body having external threads at a first end and internal threads at a second end;
- a cartridge holding a detonator;
