FIELD: oil industry, conducting of perforation operations in production wells. SUBSTANCE: shaped charges are installed and anchored in tube of perforator in correspondence with invention. They are interconnected by means of detonation cord and are linked to initiation unit. Electric communication line from initiation unit to electric lead-in in head of perforator is laid. Tube is shut by head on top and by lug from beneath. Internal space of tube is vacuumed through hole in nipple which is placed in lug before assembly. When nipple shuts automatically after termination of vacuuming process hole with nipple is sealed additionally. EFFECT: increased perforation efficiency. 1 dwg
