| 摘 要： | 从岩心相渗数据出发，经归一化处理得到油藏的平均相对渗透率曲线。针对具体油藏，结合平均相对渗透率曲线回归出Kro/Kre与Swd关系式的具体形式，并进一步推导了油藏的理论水驱特征曲线方程。实际应用中，对于薄层底水油藏（无水采油量接近为0），进一步推导了油藏水油比对数与地质储量采出程度之间的线性方程式，与薄层底水油藏实际产水情况十分吻合，因此可用于预测该类油藏的产水规律。

| Abstract: | The normalized processing of relative permeability data of cores is conducted to get the average relative permeability curves which have be regressed for the particular formula of Kro /Krw vs Swd of the reservoir.The waterflood characteristic curve equations of reservoir are then deduced theoretically.For thin layer reservoir with bottom water(water-free oil rate is close to zero),the linear equations between the logarithm of water/oil ratio and the recovery percent of OOIP are further deduced.The case study shows the theoretically calculated results are very close to the real water production of such a reservoir.So these deduced equations can be applied to predict the water production laws of thin layer reservoirs with bottom water. |
