气井积液诊断及气举排液采气技术应用OA
Diagnosis of Liquid Accumulation in Gas Wells and Application of Gas Lift Discharge and Gas Production Technology
气田在开发过程中不可避免会出现气井产液现象,当气井产量高于临界携液流量时,气体可将产出液携带出井筒,井底不产生积液,当气井产量低于临界携液流量时,由于液体滑脱导致井底产生积液.气举是日常排出井底积液的常用手段,在气田开发过程中起到非常重要的作用.判断井底是否积液是确定气井排液时机、选取气举井的基础,文章通过计算气井生产过程中的合理油套压差,绘制不同压力、不同产气量和产液量下的合理生产油套压差梯度图版,再将气井实际生产中的油套压差与合理油套压差进行…查看全部>>
In the development process of water-producing gas fields,the phenomenon of gas well water production inevitably occurs.When the gas well output is higher than the critical liquid-carrying flow,there will be no liquid accumulation at the bottom of the well.When the gas well output is lower than the critical liquid-carrying flow,the bottom of the well will produce fluid accumulation.Gas lift is a common means of daily discharge of liquid accumulation at the bo…查看全部>>
