FIELD: recovery of liquid and gaseous substances from wells; devices applicable in perforation of wells. SUBSTANCE: device has hollow body with holes in form of nozzles. Located in opposite sections of hollow body are two charges of solid fuel and initiators. The latter ensure ignition of each charge. Body is separated by partition located between charges. One charge is selected with excessive oxidizer, and the other charge, with excessive fuel. Axes of holes in form of nozzles are intersecting beyond the body. Besides, partition is made to transmit initiating pulse through delay mechanism from one charge to the other. EFFECT: higher efficiency. 2 cl, 1 dwg
