An improved electrically actuated detonator for use in oil well perforation guns is described wherein a hermetically sealed donor explosive propels a plate through a barrel cavity into a vented open space to initiate an acceptor explosive. If the open space fills with liquid the detonator fails to operate. The detonator is also resistant to actuation by radio-frequency and electrostatic energy.
An electrically activated detonator assembly for use in perforation guns which fails to detonate when immersed in liquids which comprises an elongated cylindrical outer sleeve having centrally located therein a hermetically sealed donor explosive initiator means held within a first container to propel a sheared plate in its original planar configuration through said first container longitudinally within the bore of said sleeve to strike an acceptor explosive hermetically sealed within a second container fixed at a point within said sleeve and separated f...
