STEAM-GAS GENERATOR FOR PRODUCTION OF OIL AND GAS CONDENSATE Russian patent published in 2015 - IPC E21B36/00 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: steam-gas generator for production of oil and gas condensate comprises a closed cabin with steam-gas generator mounted on the gate connected in series to adapter, tubing head, adapter and casing head of the injecting well at the deposit. Besides the generator comprises gas turbine with ejector and regenerator, piston-type compressor, electric board and electric generator coupled to gas turbine. At that the closed cabin with a door and lifting eyes comprises radiator and blower with electric motor in order to cool cooling fluid in combustion chamber of the steam-gas generator, supports with retractable rods for mounting at concrete base, water and fuel tanks placed at the cabin walls, gate couple at one side to piston-type compressor and on the other side to regenerator air duct, gas turbine placed at the cabin roof. The steam-gas generator comprises combustion chamber complete with a jacket for recirculation of cooling fluid in space between walls, with a cover and inlet valve for compressed air heated in the regenerator up to temperature of 600-700°C, outlet valve for discharge of exhaust gas to ejector and gas turbine with outlet pipe connected to inlet pipe of the regenerator or to outlet valve with tube. At that the valve gear includes a cylinder with valve piston and spring having a channel for inlet under the valve piston of compressed air from receiver equipped with return valve coupled to the piston-type compressor. Cylinder has openings for discharge of combustion products into circular cylindrical channel with nozzles installed there for injection of water and generation of stream-gas mixture. The combined nozzle comprises a body with tubes to deliver electrically conducting fluid, which are connected to cylindrical channels placed inside the body in the layer of electrically insulating material in parallel to fuel nozzle; at one side of the tubes there are electrodes connected to pulse generator and on the other side there nozzles directed at angle towards each other and interconnected by blasting chamber of the nozzle with orifice. At that regenerator for compressed air heating is made with start-up fuel nozzle, blower and electric motor.

EFFECT: increased oil recovery of the deposit reservoirs.
