FIELD: oil and gas industry.
SUBSTANCE: device has body, wherein a working body source is placed in form of a set of solid fuel charges with different abrasive particles and nozzle block with nozzles in amount of no less than three in one horizontal cross-section. Nozzle block is paced between two working body sources placed adjacently to each other by burning surfaces. These are made in form of cylinders, armored along side surface and end. End is directed to device body. Nozzles of nozzle block are hermetically plugged with plugs. Plugs are made of solid fuel with their possible combustion when reaching pressure as a result of burning of working body sources, which provides for working parameters of burning product jet from nozzles.
EFFECT: higher efficiency.
