建南单一气相管流压力计算方法研究

Research on Calculating Method of Sole Gas Phase Pipe Flow Pressure

由于气井井底压力和井底流动压力对气田的整个动态监测和生产管理都有着十分重要的作用,实时准确地掌握气井压力将有助于对气井生产系统进行分析。为了获得气井的井底压力,通过研究单一气相管流压力计算方法,进而推算获得气井井底流压。结果显示与实测数据及RTA推导结果吻合度较高,具有一定推广价值。

Both bottom pressure and bottom flow pressure of a gas well are very important in gasfield dynamic monitoring and production management.Having the real-time gas well pressure accurately in hand contributes to analyzing gas well production system.Through studying calculating method of sole gas phase pipe flow pressure,this paper calculates out gas well bottom flow pressure to obtain the bottomhole pressure.The calculation result is consistent highly with actual measurement data and RTA inference result,having some promotional value.
