FIELD: oil extractive industry.
SUBSTANCE: device has hermetical air chamber with atmospheric pressure, combustible diaphragm stop, thermo-gas chamber with combustible material, made in bodies of pipes and in upper portion connected to cable head piece. Thermo-gas chamber has in body of upper portion radial channels with destructible diaphragm valves mounted in them and combustible gas-producing material in form of inserted combustible and igniting elements having cylindrical shape with upper position of igniting element. Combustible elements provide for speed of burning 5…20 mm/s. Air chamber is placed in lower portion of device. Chambers are connected by adapter having an axial channel. Combustible stop is made for inserting and is hermetically mounted in axial channel of adapter.
EFFECT: higher efficiency.
