摘　　要：分形几何学在地质领域的研究和应用为地质现象研究提供了新的研究手段。分形分维值可以定量描述断裂分布的复杂性,分维值越大,断裂体系越复杂,越有利于油气的运移。本文通过对高邮凹陷T30、T40构造反射层断裂体系分维值的计算,发现各个反射层断裂体系具有良好的分形特征,而且分维高值区与油田分布相对应。本文指出分维高值区为高邮凹陷下一步油气勘探的重点地区。本文的研究思路在分形几何学在复杂断块油气藏的运用中具有一定的借鉴意义。Fractal theory, which is applied in the field of geology, has offered a new method for the study of geological phenomenon.Fractal dimension can be used to describe the complexities of faults system distribution.With bigger fractal dimension,the fault complex show more sophisticate,and more favorable for migration of oilgas.This paper concludes that the structural reflectors（T30、T40）show good fractal characteristic and the areas with bigger fractal dimension are in accordance with oil-producing blocks,based on the calculation of fractal dimension.Also,this paper predicts the potential profitable target of oilgas accumulation to be the areas with bigger fractal dimensions.This paper provides the meaningful train of thought about the application of fractal theory in the fault-complicated oil field.
