FIELD: oil and gas industry.
SUBSTANCE: method comprises measurement of thermobaric parameters such as wellhead pressure and wellhead temperature, determination of gas supercompressibility, maintenance of well discharge wellhead choke not less than critical by regulating, providingformation fluid export from the bottomhole. Wherein the critical well discharge is determined by the following formula: , where Q is well gas discharge necessary for liquid export through a lifting pipe, Pwh is wellhead pressure; D is internal diameter of the lifting pipe; Twh is wellhead temperature; Z is gas supercompressibility coefficient corresponding to wellhead and critical values of pressure and temperature.
EFFECT: reduced losses of retrograde condensate and prevention of liquid accumulation in wellbore.
