METHOD OF OPERATING WATERED GAS WELLS Russian patent published in 2019 - IPC E21B43/12 E21B43/34 

FIELD: gas industry.

SUBSTANCE: invention relates to methods of operation of flooded gas wells and transportation of their products. In the method of liquid removal from the bottomhole of a gas well using the technology of operation along the concentric lift tubing strings the formation fluid is supplied from the formation to the well, formation fluid is divided at the bottomhole into a gas stream and a gas-liquid stream with mechanical impurities, conveying the gas stream to the wellhead at a rate which does not provide fluid lifting, transporting a gas-liquid stream with mechanical impurities at the wellhead with pressure higher than that of the gas stream and at a rate providing lifting of the liquid with mechanical impurities, introduction of hydrate- and ice-formation inhibitor into well production, well production with hydrate- and icing formation inhibitor is transported to complex gas preparation unit. Gas-liquid flow downstream of the wellhead is directed to separation for separation from gas of liquid phase, suspended particles are separated from liquid phase, removing the precipitate, directing the cleaned liquid phase to the nearby absorbing well, introducing the separated gas into the gas stream, introducing a hydrate- and ice-formation inhibitor into the mixed gas stream and then mixed gas flow is transported with hydrate- and icing agent inhibitor to complex gas treatment plant.

EFFECT: technical result consists in increasing the flow rate of the gas well and reducing the consumption of the hydrate- and icing formation inhibitor by increasing the hydraulic efficiency of the gas-collecting pipeline and reducing its effect on operating characteristics of the water-flooded gas well.
