Abstract
A detonator assembly includes a capacitor, an initiator, a transformer and an addressable chip. The initiator is electrically connected to the capacitor, the transformer is mechanically and electrically connected to the capacitor and the addressable chip is mechanically and electrically connected to the transformer. The initiator may be bonded or fused to the capacitor, and the transformer may be bonded or fused to the capacitor. The capacitor, initiator, transformer and addressable chip form a unified integrated detonating unit.
Claims56
A detonator assembly, comprising:
- a capacitor;
- an initiator mechanically and electrically connected to the capacitor;
- a transformer mechanically and electrically connected to the capacitor;
- and
- an addressable digital chip mechanically and electrically connected to the transformer, wherein the capacitor, initiator, transformer, and addressable chip form a unified integrated detonating unit configured to respond to a command communicated from a remote source to activate an explosive;
- wherein the detonator assembly is connected with a perforating string and a carrier line, the carrier line being at least one selected from a list comprising:
- wireline, electrical cable, slickline, and tubing;
- and
- the carrier line connecting with the detonator assembly and perforating string downhole and extending uphole, wherein the remote source of the command is uphole and the command is transmitted along the carrier line to the detonator assembly.
