FIELD: oil and gas industry.
SUBSTANCE: invention relates to production of hydrocarbons, particularly to methods and systems for optimizing operation of gas wells with a complicating factor in form of flooding of a production string of a gas well. Drive of the pump mechanism is a linear valve submersible electric motor which is connected to a pumping unit of fluid pumping to form an electric submersible pumping unit. Management of the pump unit implemented based on compliance with the required pressure difference ΔP of liquid Pform of bottom of the production tubing and the gas pressure Pann at the outlet of the production tubing. Required differential pressure ΔP is maintained in real time by monitoring parameters of the liquid column in the production string.
EFFECT: raised efficiency of gas wells, reduced expenditures for operation of equipment for well de-oiling.
