Gas-lift dewatering technology of Su 4-14 by using gas from adjacent wells

    Graphical Abstract
    • Abstract
  • Su 4-14 is a deep gas well with a depth of 4825 m.The output of liquid decreased gas Production greatly.A technical measure was carried out to load the liquid in the wellbore and re-establish production difference,by using gas from adjacent high-pressure gas well.The production of Su 4-14 was resumed after the gas-lift dewatering measure in August,2005,and 1.37×107m3 natural gas and(2.0114)×103 t oil were increased by April,2006.This technology has the characteristics of low-investment and short construction period,which could be popularized to the production restoration of similar gas wells.
