摘要： Disclosed is a binary electroexplosive device including an explosive lead and a pyrotechnic explosive which may be selectively positioned to initiate the explosive lead upon combustion of the pyrotechnic material. The pyrotechnic material is contained in an initiator assembly which may be inserted within a combination socket and housing which also holds the explosive lead facing the pyrotechnic material but spaced therefrom. Insertion of the initiator assembly within the socket completes electrical connections between a power source and a bridgewire within the initiator assembly embedded in the pyrotechnic material. In a particular embodiment shown, the electroexplosive device is utilized as a blasting cap for a well jet perforating gun wherein the gun may be completely assembled with the exception of the insertion of the initiator assembly in the socket. At the well site, the electrical system may be tested for shorts or other malfunctions by a combination test and insertion tool, whereby the initiator assembly may then be seated to arm the electroexplosive device.

摘要： Disclosed are method and apparatus for cutting tubular members from the inside by use of an explosive-induced shock wave. In a particular disclosed embodiment, an electric detonator is used to initiate two equal lengths of linear explosives, each of which initiates a non-electric detonator, to provide dual simultaneous detonation of both ends of an elongate high explosive charge distribution. The resulting collision of detonation shock fronts at or near the center of the explosive charge diverts the shock energy 90.degree. into a 360.degree. distribution about the axis of the charge distribution in a plane perpendicular to that axis to provide the energy to cut a tubular member circumscribing the explosive charge.
