FIELD: oil and gas industry.
SUBSTANCE: invention is related to oil and gas simulation systems and may be used at perforation of wells with shape-charged perforators. The invention comprises a body, electric conductor, piston, cartridge with detonating cord placed inside it, detonation transmitting unit, electric detonator, and contact of electric detonator. The claimed device is equipped with movable electric contact placed at the first but end of the piston. The top part of the piston is conical. At the second butt end part of the piston there is a dead-end hole with diameter equal to diameter of the top end of electric contact in the perforator lower section.
EFFECT: simple docking of the perforation system sequential initiation device with perforator sections at assembly and increased reliability of connections.
