Abstract
Disclosed is a method and apparatus for use in initiating explosives used in application including well perforating systems. The initiator uses an air gap separating an electrically triggered semiconductor bridge plasma energy creator and a reactive foil abutting an explosive.
Claims4
An initiator apparatus for detonation of an explosive, the initiator comprising:
- a housing;
- an explosive charge in the housing;
- and means for forming plasma gases upon the application of a sufficient electrical charge, the plasma gas forming means is located in the housing at a position spaced a distance away from the explosive charge.
The reactive layer to heat the reactive layer to at least about 250 degrees C. at a rate of at least about 200 degrees C./minute when sufficient electrical charge is applied to the plasma forming means.
