摘要
基于油田开发过程中含水率、油层含水饱和度不断上升的规律，首次将Ｌｏｇｉｓｔｉｃ旋回模型引入油层饱和度的计算。该方法建立在实验室中岩心水驱油实验的基础上，对于含水率大于９０％的特高含水期不适用。
Based on the regularity of increase in water cut and water saturation in oil reservoir during oil field development, Logistic cycle model is introduced for the first time to calculate saturation in oil reservoir. This method is based on the core water displacement experiment in laboratory and ont available when water cut is over 90%.
