多相流数值试井技术在百口泉油田的应用

The Application of Multiphase Flow Numerical Well Test Technique in Baikouquan Oilfield

常规的解析试井分析方法对于多相流、多井系统、生产历史、复杂边界、复杂井网和储集层的平面非均质性等问题存在一定的困难,随着数值试井解释技术的发展,以上问题逐步得到了较好的解决。油藏注水开发后期,由于流体渗流复杂,难以确定注采井组中油水井之间的压力关系,应用数值试井技术结合动静态分析方法,可定量化的描述区域地层压力及剩余油分布状况。

There are some difficulties for traditional analytical method of analytical well test to solve like multiphase flow,multi-well system,history of production,complex boundary,complex well pattern,the heterogeneity of reservoir plane and so on.With the development of the numerical well test interpretation technique,those problems mentioned above could be better solved.For complication of fluid percolation in late period of reservoir by water-injection to develop,the pressure relationship between the oil wells and the water wells of injection-production well group is difficult to determine.While,applying numerical well test technique and combining dynamic and static analytical methods,regional formation pressure and residual petroleum distribution status could be described in quantity.
