FIELD: oil and gas industry. SUBSTANCE: fire extinguishing device for flowing wells has explosive charge delivery means 6. The latter is jet apparatus 1 provided with working agent generator 2, nozzle head 3, and nozzles 4 and 5. The explosive charge is a rotation body with spherical recess 10. The recess vertex in any of its section points is directed toward charge axis 11. The charge has cylindrical end-faces 12. As the apparatus with the explosive charge is embedded in the ground, the charge is blown up creating a shock wave to throw away the flow and crush the casing pipe. EFFECT: higher fire extinguishing capacity; higher reliability. 3 dwg
