【摘要】 本文运用分形理论对四川盆地油气田的空间分布特征进行了研究，结果表明，油气田的空间分布可以统计地认为具有自相似性，分形几何学可以描述油气田的分布规律。应用盒维数方法计算了油气田空间分布的分维值，对不同区块的分维特征进行了比较，探讨了分维值的物理意义。实际资料计算结果显示，盒子数目与尺度有很好的相关性，其相关值均达０．９９以上。更多还原

【Abstract】 Spatially distributional characteristics of oil-gas fields are studied by using fractal theory in this paper. The results show that the spatial distribution of oil-gas Fields can be regarded as having self-similarity statistically and the distributional regularity of oil-gas fields can be described by using fractal geometry. Through utilization of box counting method, the fractal dimensions of spatial distribution of oil-gas fields are calculated. In addition, properties of fractal dimensions in different regions are compared and physical significance of fractal dimension is explored in this paper. Real datum computation shows that box counting number correlates to the scale very well, with a correlation coefficient of more than 0.99.更多还原
