FIELD: oil and gas extractive industry.
SUBSTANCE: device has force and product pipelines, column of thermo-isolated pipes, steam generator. Steam generator is made in form of system for feeding easily-boiling liquid. Said system contains thermo-isolated force pipeline with reduction assembly for adjusting amount and pressure of easily-boiling liquid and sprayer. Sprayer serves for dispersing easily-boiling liquid on smallest drops and forming foam of mixture of bubbles of easily-boiling liquid steam and oil from bed. Also provided is compressor for raising foam, cooling machine for transferring steam of easily boiling liquid to liquid state. Inputting pipeline is placed coaxially outside the force pipeline. Output of input pipeline is connected to separator input, and separator output - to cooling machine input.
EFFECT: higher efficiency.
