摘要： 页岩气藏渗流规律研究对页岩气藏采收率的预测尤为重要。Romm提出的线性方程被广泛应用于计算相对渗透率曲线并用于预测气藏采收率。大量研究证明，用这种方法预测的采收率误差较大。提出了一种新的计算页岩气藏的气水两相相对渗透率曲线模型，它不仅与饱和度有关，而且还受流体黏度的影响。相对于Romm的模型，新模型可以更好地用于页岩气藏渗流规律的研究。

Abstract: The relative permeability regularity study of shale gas reservoirs has a significance in the recovery prediction of this reservoir.Although the liner function proposed by Romm is still widely used in the calculation of relative permeability to predict the gas recovery,lots of researches have manifested this function will lead to a serious deviation from the real situation. In this paper, a new model for calculating oil/water two phase relative permeability curves of shale gas reservoir is proposed, which is related to the effect of fluid saturation and viscosity. Compared with Romm model, the new model can be better used for percolation estimation of shale gas reservoirs
