Abstract
Components for a perforation gun system are provided including combinations of components including a self-centralizing charge holder system and a bottom connector that can double as a spacer. Any number of spacers can be used with any number of holders for any desired specific metric or imperial shot density, phase and length gun system.
Claims20
A perforating gun, comprising:
- an outer gun carrier;
- a charge holder positioned within the outer gun carrier and including at least one shaped charge;
- a detonator contained entirely within the outer gun carrier, the detonator including
- a detonator body containing detonator components,
- a wireless signal-in connector, a wireless through wire connector, and a wireless ground contact connector, and
- an insulator electrically isolating the wireless signal-in connector from the wireless through wire connector;
- and,
- a bulkhead, wherein the bulkhead includes a contact pin in wireless electrical contact with the wireless signal-in connector, wherein
- at least a portion of the bulkhead is contained within a tandem seal adapter, and the wireless ground contact connector is in wireless electrical contact with the tandem seal adapter.
6 more elements
A modular detonator, comprising:
- a detonator body containing detonator components;
- a wireless signal-in connector;
- a wireless through wire connector;
- a wireless ground contact connector;
- a signal-in wire electrically connecting at least in part the wireless signal-in connector to at least one of the detonator components;
- and,
- an insulator electrically isolating the wireless signal-in connector from the wireless through wire connector, wherein
- the wireless signal-in connector is configured for making wireless electrical contact with an electrical contact of a bulkhead assembly contained at least in part within a tandem seal adapter when the modular detonator is received within a gun assembly of a perforating gun system, and
- the wireless ground contact connector is configured for making wireless electrical contact with the tandem seal adapter when the modular detonator is received within the gun assembly of the perforating gun system.
6 more elements
A method for assembling a perforation gun system, comprising:
- (a) inserting a charge holder within a hollow interior of an outer gun carrier, wherein the charge holder includes a detonating cord connected to the charge holder and at least one shaped charge;
- (b) inserting a top connector into the outer gun carrier adjacent to the charge holder, the top connector comprising a hollow channel;
- (c) inserting a detonator into the hollow channel of the top connector, the detonator including
- a detonator body containing detonator components,
- a wireless signal in connector, a wireless through wire connector, and a wireless ground contact connector, and
- an insulator electrically isolating the wireless signal in connector from the wireless through wire connector;
- (d) connecting a through wire to the wireless through wire connector;
- (e) energetically coupling the detonating cord to the detonator;
- and,
- (f) transporting the perforation gun system to a wellbore site, wherein at least one of steps (a), (b), and (d) is performed before transporting the perforation gun system, and step (c) is performed at the wellbore site.
