摘要
应用分形理论来研究石油地质现象，是近年来地质学研究中的新方法和新思路。本文扼要介绍了分形和分维的基本概念和最新进展；并以四川地区为例，通过对川东、川西南、川南、川西北以及川中等地２００个气藏的统计研究，结果表明气藏的体积分布很好地遵从幂律分布规律，一定区域内油气藏的体积分布是一种分形分布。本文对分形分布的意义进行了探讨，提出了初步预测油气藏数目及储量的方法。该项成果为油气藏的研究开拓了新的领域。
It is a new method and tendency in geology to apply the fractal theory to study petroleum geological phenomena.The basic.concepts and the modern advances of fractals and fractal dimension are introduced briefly in this paper. Taking Sichuan region us an example,through the statistical study of 200 natural gas deposits in the east,southwest.south,norththis concluded that size distributions of oil-gas deposits obey power-law distrbution quite well and they are fractal distributions within a defined space.The significance of fractal distributions has also been explored in this paper. In addition,the method of prehminarily forecasting the number and the reserve of oil-gas deposits has been raised. These fruits open up a new field for the research of oil-gas deposits.
