发明名称 Liquid desensitized, electrically activated detonator assembly resistant to actuation by radio-frequency and electrostatic energies
摘要 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.
