| 摘 要： | 提出1g（Kr0／Krw）～Sw关系曲线主体部分是直线段的油田才能应用水驱规律曲线。在证实了大庆油田长垣内部及外围各油田1g（Kr0／Krw）～Sw关系曲线主体部分确实是直线段、能应用水驱规律曲线进行分析以后，从理论和大庆油田实例两方面证实了在含水50％以前及以后都可能出现水驱规律曲线的真正直线段，其出现时间取决于油层及流体性质，并给出了利用1g（Kro／Krw）～Sw和甲、乙型水驱曲线相结合确定真正直线段出现时间的方法。

| Abstract: | The paper points out that the water drive curves could be applied to the oil fields in which the main part of the 1g(Krw/Krw) ~Sw curve is straight line. Certainly proved the main part of the lg (Kro/Krw ) ~Sw curve is real linear for Changhuan internal and skirt reservolrs of Daqing Oil Fleld and water drive relation curve can be used to analyze their per formance, it demonstrates that the real linear part of the water drive curve may appear be fore/after 50% water-cut in theory and for practlcal examples of Daqing Oil Field. The ap pearing point of straight line depends on characteristics of forrnation and fluid. The paper al so gives a method to determine the appearing point for real straight line by combination of lg (Kro/Krw)~Sw relation and two different types of water drive curves. |
