FIELD: oil production. SUBSTANCE: method of mechanized production of oil is realized by sinking of submersible pump with electric motor on lifting pipes and by their immersion into oil. By supply of gas into borehole clearance pressure exceeding that of gas saturation of produced oil is formed at intake of pump. EFFECT: improved operational reliability of pump set thanks to prevention of cavitation caused by emission of gas from oil composition. 1 dwg
