초록 ▼

A perforating apparatus adapted to be disposed in a wellbore includes a plurality of shaped charges, an electrical current carrying conductor, and a plurality of exploding foil or exploding bridgewire initiators disposed, respectively, between the plurality of charges and the current carrying conductor for simultaneously detonating thereby simultaneously detonating all of the plurality of shaped charges of the perforating apparatus in response to a current flowing in the conductor. Each of the shaped charges include a new secondary explosive primer disposed in the apex of the charge for detonating in response to a detonation of the exploding foil or exploding bridgewire initiator. The electrical conductor may include a flat cable having a plurality of such initiators spaced apart at predetermined intervals along the cable and adapted to wrap helically around the perforating apparatus until each of the initiators abut against a shaped charge of the plurality of charges in the perforating apparatus. In an alternate embodiment, the electrical current carrying conductor may include a flat sheet having a specific length and width and including a plurality of such initiators. The flat sheet is adapted to wrap around the entire circumference of the perforating apparatus until each of the initiators in the sheet abut against a shaped charge of the plurality of charges in the perforating apparatus. The current in the conductor may originate from a compressed magnetic flux (CMF) current pulse generator or from a charging capacitor of a conventional system including one or more charging capacitors and associated discharge switches. When the perforating apparatus includes a first and second perforator separated by an adaptor, the adaptor includes a pressure bulkhead adapted to seal the first perforator from the second perforator, an explosive disposed in contact against one side of the bulkhead and a piezoelectric ceramic disposed in contact against the other side of the bulkhead.
