摘要
根据南堡凹陷东营组以上各组底界断裂分布图,利用分形理论容量维数法检验了断裂空间分布具有很好的自相似性,相关系数0.98～1,断裂系统具有分形结构.计算并绘制了南堡凹陷东营组以上各层底界断裂分维值等值线图,指出了油气聚集的有利区带,并从分形学的角度分析了断裂对油气藏形成的影响以及分维值分布特征对构造活动的反映.
According to figure of faults distribution in the bottom of Minghuazhen formation of Nanpu basin, self-similarity of fault spatial distribution has been examined by using fractal theory and the fractal dimension of capacity. Correlation coefficients are between 0. 98 and 1, which suggests that faults are fractal structure. The fractal dimension of capacity (D0) in different areas of every layer above Dongying formation have been calculated and its isoline map is drawn. Favorable areas have been pointed out for prospecting of petroleum and natural gas. Faults'influence to oil-gas to reserve and fractal dimension' reflection to tectonic have been analyzed on the basis of fractal.
