在这项工作中，提出了新的关系，它允许再现具有良好的精度，无论是气体-油排水和水-油渗吸相对渗透率曲线。建立了油气相对渗透率的四参数指数方程和油水相对渗透率的五参数指数方程。一些参数具有物理意义，其值可以通过实验确定;其余参数具有经验性质，其值必须通过现有数据点的非线性回归计算。利用所提出的关系，给出了气-油和水-油相对渗透率曲线的拟合结果。参考文献14篇。
Novel relations are proposed in this work, which allow reproducing with good accuracy both gas-oil drainage and water-oil imbibition relative permeability curves. The proposed relations are four-parameters exponential equations for gas-oil relative permeabilities and five-parameter exponential equations for water-oil relative permeabilities. Some of the parameters have a physical meaning, and their values can be experimentally determined; the remaining parameters are of empirical nature and their values must be calculated through-non linear regression on the existing data points. Results are presented of the matching of both gas-oil and water-oil relative permeability curves, using the proposed relations. 14 refs.
