古潜山灰岩裂缝分布的分形特征

相似维数对于定量评价储层裂缝平面分布的非均质性和裂缝的发育程度，是一种实用性很强的非线性统计方法，并对平面上裂缝发育程度具有很强的定量描述能力。裂缝发育的线性分布曲线表明，裂缝分布具有分形几何特征。运用变尺度分形统计方法，统计了储层裂缝发育区平面分布的相似维数，理论和实际资料都证实该充填空间能力较差，裂缝发育程度不是很强，这与目前该油气藏的地质特征及产能情况比较吻合。

The Fractal Characteristics of Fracture Distribution of Buried Hill Carbonate Rock

By using fractal statistics method,the fractal similar dimension of plane distribution of fracture developed regional was counted.Fractal dimension can be used for showing the heterogenous of fracture plane distribution both in theory and in practice,and which has strong ability of quantitative depiction.Fractal similar dimension is a kind of nonlinear statistic method that has strong pragmatic for describing the extent of fracture developing.A new kind of statistic method was used for describing fracture distribution.The linear curve of fracture developing shows that fracture distribution has fractal charycteristic.The statistic result of fracture distribution shows that the regional fracture stuff ability is relatively poor,and that the extent of fracture developing is not strong,which is comparatively identical to the yield condition and characteristic of the reservoir.
