通过对川中大安寨段介壳灰岩中裂缝进行非常规自相似特征分析，探讨了裂缝及储层岩石孔隙结构的分形特征，认为岩石中的裂缝和孔隙都是复杂的分形体，运用实际资料证实了这种分形体的长程相关性，定量计算出分形维数，该维数可以作为定量评价单井裂缝发育程度的重要参数。以此为基础，提出了新的孔隙结构模型——阶梯状孔隙结构模型。
Based on the analysis of the unconventional self-similar features of the cracks in the Caledonian limestone in Daanzhai Section of Central Sichuan Basin, the fractal characteristics of the fractures and pore structures in the reservoir rocks are discussed. The fractures and pores in the rock are both complex fractal bodies. The actual data confirm According to the long-range correlation of the fractal, the fractal dimension can be calculated quantitatively, which can be used as an important parameter to quantitatively evaluate the development degree of a single well. Based on this, a new model of pore structure, a model of stepped pore structure, is proposed.
