榆林气田T区气藏数值模拟跟踪研究

The tracking study in numerical simulation of the T areas in Yulin gas field

经过5年的滚动开发,到2005年底榆林气田T区累计建井172口,形成年产20×10~8 m^3天然气生产能力,成为长庆又一重要天然气生产基地。随着榆林气田T区产能建设的结束,气田进入稳产阶段。因此,深化地质研究,开展数值模拟跟踪研究,通过对拟合、修整好的数值模型,预测相关开发技术指标,最终优选最佳的开发方式,为该区合理开发提供依据。

By 5 years＇ rolling development,the T areas of yulin gas field has constructed 172 wells accumulatively,having formed the capacity of 20×10~8 m^3/a,which becomes another important production base in changing oilfield.With the end of the construction output of T areas,the gas field come into the stable production phase.As a result,through fitting the amended geological model,we have predicted the development of technical indicators and optimized of the best development method,providing the basis for the rational development of well area.
