FIELD: oil production industry, particularly to produce light oil. ^ SUBSTANCE: method for creating continuous gas-liquid flow, depressing thereof and delivering the flow to ground surface involves passing gas-liquid flow through well filter; directing the flow to turbine installed at lower end of production string and rotating the turbine due to gas-liquid mixture inflow, which provides oil reservoir energy; forming rotational moment in drive of separator, where gas-liquid mixture is separated into gas and liquid and directed along gas ascending line defined by channel connecting casing pipe and flow string; passing liquid via channel defined by flow string interior; separating gas and liquid ascending lines with packer; creating pressure at well head, which depressed liquid flow by means of ejector connected to liquid ascending line and supplied from gas ascending line to provide additional gas emission from ascending liquid flow; regulating gas pressure with bypass line and valves. ^ EFFECT: provision of continuous gas-liquid flow and depression thereof along with gas-liquid flow delivery to ground surface. ^ 1 dwg |
