Plasma gap detonator with novel initiation scheme

摘要

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.

主权项

1. An initiator apparatus for detonation of an explosive, the initiator comprising:
a housing; a reactive element located in the housing; a semiconductor bridge located in the housing configured to form a plasma gas upon application of a sufficient electrical charge; and an air gap positioned between the reactive element and the semiconductor bridge element, wherein the air gap is dimensionally configured to prevent stray energy from igniting the reactive element during transfer of the stray energy.
