FIELD: oil and gas industry.
SUBSTANCE: fire-fighting method of blow-outs on wells with water-gas streams formed with water supplied to exit gas stream of aircraft jet turbine engine mounted on movable device involves initial cooling of Christmas tree, cutout of burning blow-out from well bottom and further blow-out fire-fighting. At that, supply of fire-fighting powder is performed in pulse mode to blow-out zone above water-gas streams; at the same time, blow-out fire-fighting with water-gas streams is continued. Fire-fighting powder is supplied from the position of movable device and in the direction which is similar to the supply of water-gas streams.
EFFECT: improving fire-fighting efficiency.
