| 摘 要： | 本文将分形几何学的原理和方法，应用于东营凹陷Ｔ２，Ｔ６和ＴＲ３个不同构造层的断层体系的二维平面分布特征研究，发现在研究的标度范围内（ｌ＝０．５－４ｋｍ）不仅具有统计自相似性，并且同一构造层不同子区域不同的分维值Ｄ．分维值分布特征为南区分维值略低于北区分维值，东区分维值略高于西区分维值，将本区断层体系的这种分维值布特征与油田分布特征对比，可发现分维值越高，油田规模越大。

| Abstract: | The principles and methods of fractal geometry are applied to the study of fractal characteristics of three different two-dimension-plane fault systems of structural layers T2, T6 and TR in Dongying depression. As a result of this study, authors discover that these fault systems not only possess statistical self-similar characteristics in scale extent studied (1=0.5km to 4km), but also have different D values of fractal dimension in different sub-ranges of the structural layers. The distribution of D values of fractal dimension in sub-ranges shows that D value in south sub-range is slightly lower than that in north sub-range and east sub-range is slightly higher than that in west sub-range. Comparing characteristic distribution of D values with that of oil fields in Dongying depression, it can be noted that the higher the D value, the larger the oil field in the same spacial location. |
