摘要
提高油藏描述的精度、确定剩余油的分布、改善开发效果的关键是认识油藏的非均质性。介绍一种研究油藏非均质性的新方法———流动单元研究方法。流动单元不仅具有相同（似）的沉积特征，而且具有相同（似）的流动特征。将流动单元的研究方法分为２种，一种是岩心定性分析方法，另一种是修改的ＫｏｚｅｎｙＣａｒｍａｎ方程方法，给出了流动单元研究的步骤。介绍了流动单元在储层评价、剩余油分布与预测、油藏数值模拟、渗透率解释等方面的应用。
The key to increasing accuracy of reservoir description, delimiting distribution of residual oil and enhancing reservoir development is to know the reservoir heterogeneity. Here we introduce a new method of understanding and studying reservoir heterogeneity —— studying methods of flow units. Flow units have not only the same(similar) sedimentation characteristics, but also the same(similar) flow characteristics. The studying methods of flow units are classified into two kinds. One is core analysis method, the other is modifying equation of Kozeny Carman method. Steps are give about studying flow units and introduces application of flow units to reservoir evaluation, residual oil distribution, reservoir numerical simulation and permeability interpretation.
