FIELD: equipment for secondary tapping-perforation of bottom-hole formation zone by blasting. SUBSTANCE: device includes hollow-carrier jet-type perforator with head and sealed side holes, jet chargers, tip and two sealed air chambers with atmospheric pressure. Sealed air chambers are located at ends of perforator. Powder charges are located in sealed air chambers. Located between powder chargers and jet charges are protective blocks from nondetonating mixed fuel of elastic type. EFFECT: creation of additional energy carrier forming powerful flow of gases in well during operation of jet charges. 1 dwg
