| 摘 要： | 储层非均质性是影响油气田勘探和开发的重要因素.储层岩石孔隙具有分形特征,分形维数可以定量地表征储层的微观非均质性.本文简述了孔隙分布概率密度函数、分形判据等分形理论基础,系统分析了利用压汞测试法,毛细管力曲线法和计盒法等计算分形维数的方法,以及分形维数解析研究的进展,并对进一步研究做了展望.

| Abstract: | Reservoir heterogeneity has a great influence on the oil-gas field exploration and development.The reservoir pore structure shows fractal characters and fractal dimension can quantitatively characterize the microscopic heterogeneity of reservoirs.In this work,the theoretical basis of fractals are briefly introduced,including the probability density function of pores and a criterion for a medium can be analyzed by fractal geometry.The methods and advances on predicting fractal dimension using mercury intrusion test and its capillary pressure curve,and analytical studies are analyzed systematically.Comments and prospects are discussed in the last. |
