摘要： 利用压汞曲线计算出来的分数维来定量表征储集层微观孔隙结构的非均质性:提出“基于盒维数的测井曲线刻度线网格加密法”,利用单砂体测井曲线计算的分数维来定量表征储集层层内及层间等宏观非均质性。最后,按照同一微相、同- -单砂体层位将储集层微观分维与宏观分维联系起来建立储集层分维模型，从而实现了将微观非均质性的定量表征扩展到单砂体规模的宏观非均质性的定量表征。结合实际以某注水开发中后期油田的河流相砂岩储集层为例展开研究，应用效果较为理想。

Abstract: The fractal dimension calculated from mercury injection curves is used for quantitative characterization of heterogeneity in micro-porosity structure of reservoir. A method of the grid refinement of case dimension-based log calibration is presented. The fractal dimension given from single sand body logs is applied for quantitative characterization of macroscopic heterogeneity in inner- and inter-layer. These two fractal dimensions are combined to develop a reservoir fractal model by which the microscopic heterogeneity's quantitative characterization can be expanded into the macroscopic heterogeneity's quantitative characterization of single sand body. An example of fluvial facies sandstone reservoir in a water flood oilfield at stage of moderate-high water cuts is taken for this study, and perfect effectiveness for application is obtained.
