FIELD: gas lift oil wells for reservoir fluid development and methods of reservoir gas usage for production thereof, as well as electronically operated downhole valve.
SUBSTANCE: well comprises production string extending inside well through oil-bearing and gas-bearing zones and electrically operated downhole valve. The valve is connected with production string and adapted to regulate high-pressure trip gas flow. Well is provided with connection means, which supplies gas from gas-bearing zone in downhole valve, inductive throttle arranged around production string near downhole valve to transmit electric power and control signals by production string to downhole valve through the first and the second outputs. The outputs are linked with production string from power source side and from return circuit side of inductive throttle correspondingly. Method for above well operation is also disclosed.
EFFECT: increased efficiency and operational reliability.
