用试井方法分析百口泉组油藏储集层物性变化

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。数值试井技术相当于井组区域的数值模拟，它通过拟合油水井生产历史和实测压力曲线，给出压力及剩余油分布状况，并能直观地展布储集层特性变化特征。引入了数值试井技术，并结合常规的解析试井分析方法，综合分析了该油藏储集层历史变化特征。

Analysis of Petrophysical Property Variation of Baikouquan Reservoir with Well Test Method

Some problems always occur for using conventional analytical well test method to analyze multiphase flow, muhiwell system, production history, complex boundary, complicated well pattern and plane heterogeneity of reservoir. The numerical well test interpretation technique is equivalent with numerical simulation of well group. It can provide for specific pressure and remained oil distribution and intuitionistic characteristics of a reservoir property variation through matching oil/water well production history and measured pressure curves. This paper introduces the numerical well test interpretation technique, integrates with conventional analytical well test analysis result and comprehensively analyzes the varied production historical features of Baikouquan reservoir.
