FIELD: oil and gas production.
SUBSTANCE: method includes gaslift well operation by adjusting the flow rate of working and produced gas. The withdrawal of produced gas is done by tubing string and additional tubing string. The flow rate of working and produced gas is adjusted by opening and closing of driven shut-off elements in accordance to the control signals. Control signals come from automatic control unit and are generated according to the results of measured values compared with set parameter values. Note that the pressure is measured in the mouth and bottom hole, at the same time the flow rate of produced gas is measured. The flow rate of working and produced gas is adjusted in such a way to provide the specified well operation mode.
EFFECT: increase of well operation efficiency, reduction of level and removal of fluid accumulated in bottom-hole zone, provision of well operation stability.
