Principle and Field Application of Immobile String Rapid Flow Valve Technology
The high-temperature and high-pressure gas field in the Yinggehai Basin of the western South China Sea oilfield plays an important role in stable gas supply in the Hainan area.Currently,most wells in the Dongfang 1-1 oilfield have entered the late stage of oilfield development,and some wells have problems with underground safety valve leakage,which need to be treated in a timely manner.The process of using immobile string to inject a velocity flow valve is an effective alternative to downhole safety valves,which can control the safety of gas wells by opening and closing the valve disc through pressure difference and gas production.This process can achieve the control of underground safety valve leakage hazards without moving the pipe column.The successful application of the rapid flow valve has significant reference significance for the leakage control of underground safety valves in production gas wells in the western South China Sea oilfield.
