Effect Evaluation of Drainage Gas Recovery by Velocity String in Sulige Gas Field
2018The universal features of the gas wells in Sulige gas field are low pressure, low production rate, and the liquid-carrying capabilities of the wells that are poor. Accompanied with the gas well entering the process of middle and late life span, the pressure of the well bottom gets low and the liquid-carrying capability of the well becomes poorer ...
