Purpose of gas lift
Coiled tubing equipment and nitrogen or low-density liquid are utilized to replace high-density liquid inside wellbore with low-density liquid to make pressure of liquid column inside wellbore lower than formation pressure and realize flow production of oil wells, thus helping oil-producing formation recover liquid production.
Coiled tubing gas lift is applied when related requirements are not met by using
This process makes kill job unnecessary.
Nitrogen does not bring any corrosion to downhole tool and tube.
Short operation time is guaranteed.
