摘　　要：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。Through the research into unusual self similar characteristic analysis of the fractures in the Daanzai limestone reservoir, this paper concludes that fractures and pores in the reservoir rock are complex fractal systems. Fractal dimension is quantitatively calculated, which can be used to evaluate the development level of fractures quantitatively. Based on the research,a new kind of pore fracture model is put forward,which is a good and reasonable model.
