METHOD OF UNINTERRUPTED OPERATION OF GAS AND GAS CONDENSATE WELLS, PROVIDING REMOVAL OF ACCUMULATED BOTTOMHOLE FLUID Russian patent published in 2020 - IPC E21B43/12 E21B47/06 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to gas industry, in particular, to operation of gas and gas condensate wells. In the disclosed method, pressure ranges in the well are determined in a static mode with subsequent calculation of gas lift valves opening pressures, adjusting the gas lift valves by the calculated pressure, after which tubing string is lowered into plugged gas or gas condensate well to depth of holes arrangement in perforation interval, gas lift gas is then fed into annular space of the well with pressure at which gas lift valves are opened. Further, by increasing the pressure of the gas lift gas, bubbling of the liquid column is created, leading to displacement of the gas-liquid flow from the bottomhole along the tubing string.

EFFECT: method ensures timely removal of accumulated liquid from well bottomhole and increases overhaul period of operation of gas and gas condensate wells.
