摘要(Abstract)：

流动单元是垂向及横向上连续的、影响流体流动的、岩石物理性质相似的储集岩体。其概念的内涵大体经历了从沉积相单元到岩石相单元再到岩石物理相单元等不同阶段,流动单元的划分体现了定量描述和评价油气储集层非均质性的新思路和新方法。划分流动单元的新方法具体包括①根据断层、隔层、夹层、渗透率韵律、层理、裂缝、孔隙结构等控制流动单元边界的成因分类法;②沉积岩相划分法;③以地质研究为主的储层层次分析法;④利用流动层段指标(FZI)、压汞曲线上进汞饱和度达35%时的孔喉半径(R35)等参数值的岩石微观孔隙结构法;⑤利用渗流系数、存储系数、净与毛厚度比的分类法;⑥利用振幅、波阻抗属性的地震属性分析法。其中前3种以宏观地质、沉积岩相及岩石方法为主;第4,5种方法以微观、定量的岩石物理参数为主要依据;第6种基本上属于间接方法。根据储层流动单元法建立的三维储层非均质模型为油田开发提供了新的可靠的地质依据。
