裂缝发育区平面分布的分形评价

裂缝是一种具有强烈非均质特征的油气储集 体，其在三维空间内的分布具有非 线性特征。运用相似维数统计法对裂缝发育带在二维平面内分布的分形特征进行研究，并用 该定量参数进行层间裂缝发育程度的定量对比。理论上证实，相似维数这一分形参数可以定 量表征裂缝发育带对二维空间的充填能力，实际统计结果表明，裂缝发育带的统计相似维数 高低与层间总体产能的对比关系是完全吻合的。

Fractal Evaluation on Plane Distribution of Fracture Zone

Fracture is a kind of oil and natural gas storage body with high heterogeneity. Its distribution in the 3 dimension space has nonlinear characteristics to a certain degree. In this paper, similar dimension statistical method has been used to study the distribution of fracture zone, and the parameter is used to compare the fractures' development of several sand layers quantitatively. It has been proven theoretically that the fractal parameter of similar dimension can be used to evaluate quantitatively the filling capacity of fracture zone to 2 dimension space, and the practical statistic result shows that the level of similar dimension of fracture zone coincides well with the comparing relation of production situation of each sand layer.
