运用分形几何学的方法，对辽河油田洼３８块变质岩潜山油藏裂缝型储层的裂缝发育程度分布特征进行了研究，发现储层裂缝发育程度和分布具有自相似性，可用分形几何学进行描述。介绍了求取储层宏观裂缝分维值的盒维数方法和求取储层微观裂缝分维值的康托点集法。储层裂缝分维Ｄ值是描述储层裂缝发育程度的定量参数。在碎屑岩中裂缝最发育，分维值最高；其次为混合花岗岩；辉绿岩脉裂缝发育程度最差，分维值最小。
Fractal geometry is used to study the distribution of fractures in fractured reservoirs of depression 38 reservoirs in Liaohe Oilfield. It is found that fractures have a similar degree of self-similarity and distribution. Fractal geometry Describe. The box dimension method for determining fractal dimension of macroscopic fractures in reservoir and the Cantor point set method for obtaining fractal dimension of microcosmic fractures in reservoirs are introduced. The fractal D value of reservoir fractures is a quantitative parameter that describes the degree of reservoir fracture development. In the clastic rocks, the fractures are the most developed with the highest fractal dimension value, followed by the mixed granites. The diabase dikes have the least developed fractures with the smallest fractal dimension.
