摘要： 介绍了第二种类型的水驱特征曲线$N_{p}=f((\frac{1-f_{w}}{f_{w}}))$的7种表达式,并研究了它们的特点,指出第9~第14种水驱特征曲线表达式是完全等价的,可表示为$N_{p}=a-b(\frac{1-f_{w}}{f_{w}})^{1/2}$表明它们具有相同的驱替特征;而第15种水驱特征曲线方程可表示为$N_{p}=a-b(\frac{1-f_{w}}{f_{w}})^{1/3}$.

Abstract: This paper described seven expressions of the second category of water displacement curve $N_{p}=f((\frac{1-f_{w}}{f_{w}}))$,and pointed out that the formulae (9) ~ (14) are equivalent, which can be expressed as $N_{p}=a-b(\frac{1-f_{w}}{f_{w}})^{1/2}$, while water displacement curve expression (15) can be expressed as $N_{p}=a-b(\frac{1-f_{w}}{f_{w}})^{1/3}$.
