FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, namely to structural part of perforation systems lowered into oil or gas wells, and can be used for perforation of several spaced intervals in one round-trip operation for any electric initiating means, including those actuated by alternating-current pulse. Device for consecutive initiation of perforation system includes housing, electric detonator, cord detonating, electric wire, device for transfer of detonation, electric contact. At end of electric contact on inner side of device on side of detonator there is a magnet, and opposite – at actuation distance – reed relay, and as detonator there used are detonators with deceleration.
EFFECT: reliability of the device is provided.
