根据一种理想岩石孔隙结构模型和流体在水平圆管中层流流动的理论，利用岩石进汞和退汞毛管压力资料推导出了计算岩石渗透率的公式；在此基础上，进一步考虑岩石的润湿性和饱和历史，推导出了计算相对渗透率的公式，为油田开发设计和油气采收率预测中相对渗透率的确定提供了一种有效的新方法。实例计算表明，用该公式计算的相对渗透率和实测的相对渗透率吻合很好。
Based on an ideal pore structure model and the theory of laminar flow in a pipe,equation for calculating rock permeability has been derived by using the mercury injection and ejection capillary data. Moreover, the equation for calculating relative permeability is also derived by considering rock wettability and saturating history. It is a new and efficient method for the determination of relative permeability in oil field development design and oil and gas recovery prediction. According to the calculation results,the calculated and actual relative permeabilities are in good agreement.
