应用甲型水驱特征曲线计算油水相对渗透率曲线,具有比乙型水驱特征曲线计算更稳定、结果更可靠的优点。因此,对初期未做室内相对渗透率曲线实验的油田(或区块) 来说,用本文所介绍的方法可以拟合出一条实际相对渗透率曲线。

The article discusses how to use the first water drive characteristic curve to calculate the relative permeability curve. The reliability and stability of the result using relative permeability curve are better than the second characteristic curve. If there isn’t a relative permeability curve in laboratory , you can use the method to calculate the practical relative permeability curve.
