　　为了准确、简便地计算油藏的相对渗透率曲线，根据水驱油田的水驱规律特征，在前人研究的基础上，从俞启泰水驱曲线出发，提出了计算相对渗透率曲线的新方法，并通过实例将该方法的计算结果与实测值作了对比。结果表明：当油田处于中低含水饱和度阶段时，油水两相相对渗透率与实测值大致相近；当油田为高含水饱和度阶段时，油相相对渗透率较实测值小，而水相相对渗透率则比实测值要大。而通过修正的相对渗透率曲线与油田实际生产的含水上升规律进行对比表明，所提出方法的计算结果是准确、可靠的，能够真实地反映油藏的相渗特征。

In order to calculate the reservoir relative permeability curves accurately and simply, according to the water flooding rules of water drive oilfields, based on the previous studies and starting from Yu’s water drive curve, a new calculation method of relative permeability curve is established. By examples, its calculation results are compared with the measured values. The study results show that the oil/water relative permeability is similar to the measured value when the water saturation is medium-low. The oil phase relative permeability is smaller and the aqueous phase relative permeability is larger than the measured value when water saturation is high. It is indicated that the calculation results of the proposed method is accurate and reliable, and can truly reflect the relative reservoir permeability characteristics by comparison of corrected relative permeability curves with the water cut increasing rules of the actual oilfield production.
