摘要:

选择合适的尺度,可用盒维数方法计算四川盆地油气田空间分布的容量维值;但运用多重分形理论能更有效地检验断层空间分布的自相似性。四川地区各带多重分维值的结果表明:油气田和断层的空间分布均为分形结构,具有很好的自相似性,相关系数均达到或超过0.99;油气田与断层空间分布上有密切关系,断层空间分布的容量维、信息维及关联维在1.02,1.03及1.04左右的区域,是油气的主要富集区。因此,四川地区应加强川东南、川中以及绵阳-乐山-带的油气勘探开发,其它区域的勘探重点应放在深层次的油气藏上。

Abstract:

Selecting pertinent scale, the spatial distribution capacity of oil-gas fields in SichuanBasin can be calculated by fractal dimensions. Meanwhile,self-similarity of fault spatial distribution can be examined more effectively by using multifractal theory. Calculating results ofmultifractal dimensions of different zones in Sichuan Region show that spatial distribution ofoil-gas fields and faults are fractal structures and have quit.6 well self-similarity with correlation coefficients better than 0. 99.Oil-gas fields are closely related to the spatial distributionof faults in these zones.The fractal dimension of capacity, information dimension and correlation dimension of fault spatial distribution are about 1.02,1.03 and 1. 04. These zones aremain oil-gas enriched provinces.Therefore, oil--gas exploration and development should bestrengthened in southeastern and central Sichuan and Mianyang--Leshan Regions and in otherplaces,hydrocarbon exploration should be focused on deep-seated pools
