FIELD: oil-and-gas production.
SUBSTANCE: invention related to oil-and-gas production and ment for high viscosity oil production using thermal treatment of oil layers their and supply with working medium - water. Reservoir supplied under pressure higher then it owns with heated water through pressure pipeline and withdraw oil to the surface through intake pipeline. At the same time treated with a pressure and temperature, which exclude water or liquid transition into steam state inside of the pressure pipeline, but sufficient enough to execute this transition at the pipeline exit. Generated steam supplied into oil reservoir.
EFFECT: high viscosity oil reservoir production efficiency increase with the help of more intensive heating due to water stem generation with the its following injection to the oil reservoir area.
