FIELD: oil and gas production.
SUBSTANCE: invention refers to production of oil, gas and gas (hydrocarbon) condensate, particularly to process of lifting liquid from gas condensate deposits with low gas factor under conditions of abnormally low reservoir pressure. According to the procedure of lifting liquid from bottomhole of gas condensate wells with low gas factor under conditions of abnormally low reservoir pressure by means of liquid and solid foaming agents the well is treated by separate simultaneous effect onto two zones of treatment with two types of surface active substances: liquid surface active substances are supplied into annular space and solid active substances are supplied into tubing string of the well.
EFFECT: facilitating efficient lifting of reservoir hydrocarbon containing liquid from gas condensate wells with low gas factor under conditions of low and abnormally low pressure in pay reservoirs.
