Abstract
FIELD: oil and gas industry. SUBSTANCE: perforator is intended for gas and oil wells. It has shaped charges in separate hermetic body with framework for their fastening, detonating cables and initiating means. Framework for fastening charges is in the form of separate longitudinal strips with openings for head of charge which are connected by replaceable rings corresponding to diameter of perforator. Perforator ensures more unification of frameworks for perforators of various type-sizes, allows for variation of phasing of charges and density of perforations within wide limits, and also for higher strength and rigidity of frameworks. EFFECT: high efficiency.
