| 摘 要： | 依据油藏工程理论，推导出了油水两相渗流条件下用含水率求解油层含水饱和度的方程，并借助含水率与含水饱和度的关系曲线，推导出确定砂岩水驱油藏生产井出口端地层含水饱和度的方程，应用实例表明，该方法在断层少，含油层系单一的小型断块油气田具有一定的实用价值。

| Abstract: | Based on reservoir engineering theory, this paper provides a formula for solving water saturation by water cut in the conditions of oil and water seepage flow. With the relationship curve of water cut and water saturation, the formula which calculates water saturation of exit-end formation oil well in water drive sand stone reservoir is derived. The method is practical for the small fault-block oil and gas fields, which are a few fault and simple reservoir. |
