| 摘 要： | 讨论了济阳坳陷上第三系馆陶组河流沉积的粒度特征，在对１４口岩心井３００块样品粒度分析的基础上，研究了粒度参数与水动力条件之间的关系，总结归纳出不同微相的概率曲线特征，并利用Ｃ－Ｍ图、萨胡判别式和粒度离散图研究了河流类型．研究结果表明，不同性质的河流，其粒度在垂向上的变化速率不同，直接影响到砂体的非均质性．

| Abstract: | The relationships between the grain size parameters and the hydrodynamic conditions of various sedimentary microfacies are studied on the basis of granulometric analysis data of 300 samples from 14 core wells. The probability curves of different microfacies are summarized. CM pattern, Sahu formula and the scattergram are used to study the tapes of river. It is concluded that the difference of rivers resulted in the different change rate of the grain size on vertical section. The anisotropy of the sandbodies were affected directly. |
