PLANT FOR GAS-VAPOUR MIXTURE PRODUCTION Russian patent published in 2017 - IPC E21B43/24 E21B36/00 

FIELD: oil and gas industry.

SUBSTANCE: plant for gas-vapour mixture production is characterized in that it comprises a steam-gas generator, consisting of a mixing head, a water-cooled combustion chamber and a mixing chamber. The mixing head comprises a housing, at the ends of the housing an outer and a fire bottom is fixed, two-component centrifugal nozzles are arranged uniformly across the circle, fuel manifold is mounted on an outer surface of the housing. The output portion of the combustion chamber is made as a nozzle, the combustion products flow feeds through it at an angle to which the water is supplied from the cooling loop of the combustion chamber. Turbopump assembly is mounted at the output of the mixing chamber, consisting of a water pump and a turbine mounted on the same shaft. Moreover, the water pump outlet is connected to the combustion chamber cooling loop.

EFFECT: increased efficiency of the gas-vapour impact on the oil reservoir.
