FIELD: oil and gas industry.
SUBSTANCE: gas generator includes the main solid fuel charge, ignition device in cylindrical housing with sealing assemblies in upper and lower parts and fixed piston in upper part of cylindrical housing with possibility of its being cut at the specified external pressure, and temperature promoter. According to the invention, lower end of tubing string is plugged with plate with central hole for installation of hydraulic connection of tubing string and ignition device located in lower part of gas generator. A tube connecting the tubing string to the top of ignition device is inserted into that hole. External perforated housing with solid fuel for combustion transfer to the main solid fuel charge is arranged in addition in ignition device connected to the main solid fuel charge by means of clutch coupling. Lower part of ignition device is plugged with solid fuel plate and cylindrical perforated limit switch.
EFFECT: thermal gas chemical treatment of wells with low flow rate and non-operating oil and gas wells.
