Improving methods for removing liquid from the bottomholes of gas and gas condensate wells

The problem of increasing the efficiency of gas and gas condensate wells operation, complicated by the accumulation of liquid at the well bottom, is relevant not only for Russian, but also for global gas production. A complication that is observed during long-term operation of gas and gas condensate wells is the accumulation of liquid at the well bottom. Additional pressure of the liquid column in the wellbore on the formation leads to a decrease in the wellhead pipe pressure. In addition, as the liquid phase extraction increases, the additional liquid carried away by the gas (the liquid filling the column) increases the pressure gradient in the elevator column and further increases the back pressure on the formation, thereby reducing the wellhead pipe pressure. To improve the efficiency of gas and gas condensate well operation complicated by liquid accumulation at the well bottom, a pump-ejector system layout for mechanized pump operation of flooded gas and gas condensate wells with a liquid spraying device made in the form of a jet apparatus is proposed. The technical result achieved consists in increasing gas production and extending the periods of profitable field development due to increased well operation efficiency at lower pressure values of submersible pumping units.
