该文介绍了碎屑岩储层流动单元的概念、研究意义以及研究方法,并以陕北富昌地区延长组长2段储层为例,应用储层流动层带指标FZI值进行了流动单元划分,根据薄片鉴定、图像分析、扫描电镜、压汞等资料研究了各流动单元的岩石物理特征.研究区延长组长2段储层可划分为5类流动单元,它们之间具有独立的孔隙度与渗透率关系.研究结果表明:应用流动层带指标FZI值进行流动单元划分是开展储层分类与评价以及成因分析的有效途径.

This article introduced the concept and the research approach of elastic reservoir flowing unit. Taking the Chang 2 reservior of Upper Triassic in Shanbei Fuchang area as an example, the flowing units are divided according to flowing index FZI. The petrophysical characteristics of flowing units are studied on the basis of experimental data of thin section analysis, image analysis, SEM, mercury penetration and so on. The Chang 2 reservior can be divided into 5 kinds of flowing unit by flowing indexes FZI . Every kind of flowing unit has certain relationship between porosity and permeability. The result shows that the method of the classification of flowing unit with FZI is efiqcient path for the classification, evaluation and genetic analysis of reservoir.
