相对渗透率曲线和毛管压力曲线,是储层的两项重要特性参数,本文提出了两种曲线的标准化方法。相对渗透率曲线和毛管压力曲线,通常是在模拟储层条件下,在实验室的小岩心上直接测量的。两项参数的不同曲线,由本文的标准化方法可以得到无因次关系。该无因次关系可以用于储层特性的对比和得到具有代表性的储层的相对渗透率曲线和毛管压力曲线。

Since the parameters of the permeability and the capillary pressure curves are important for characterizing reservoirs,the standardization of these two curves is proposed in this paper.Generally,permeability and capillary pressure curves of reservoirs are measured directly from experiments on small core samples under simulated reservoir conditions.With the different curves of the two parameters,dimensio-nless relationship can be abtained by the standardization suggested in this paper,which may be used in the correlation of reservoir properties and to obtain typical curves of the permeability and capillary pressure for the reservoirs.
