摘　　要：油水相对渗透率曲线是一项重要的油田开发基础数据,实验室中常通过分析岩心非稳态驱替数据获得,其分析方法存在一定不足。为此,通过改进计算公式得到了一种非稳态法处理油水相对渗透率曲线的新计算方法,该方法能够克服前人有关数据拟合的过于简单或多项式拟合非单调性的缺点,且计算结果与相关参考文献的图解结果具有良好的一致性,易于编程求解,提高了计算的合理性和准确性。Oil/water relative permeability curve is fundamental for oilfield development. This curve can be got in lab according to the analysis of cores unstable state displacement data, and there is certain disadvantage for this analysis method. So, a new calculation method for unstable state oil/water relative permeability curve is obtained based on the modification of the calculation formula. This method can avoid the former disadvantages, such as unduly simple data matching and the non-monotonieity of polynomial fitting, and the calculation results can accord with the graphical solution results of the relative references. With the application of this method, it is easy for programming and resolution, so, the reasonability and accuracy of the calculation is improved.
