中文摘要：
本文针对一维非稳态岩心驱替过程,利用多孔介质多相流动数值反演算法,提出了对一维非稳态驱替实验进行数据处理的方法。利用该方法,可以在毛细数适中的情况下同时求得毛细压力曲线与相对渗透率曲线,简化了驱替实验的复杂程度;比较了反演方法与JBN方法的准确性与适用性,结果表明在对半经验公式的形式推测合理的前提下,反演方法具有更大的适用范围和更好的准确性。该数据处理方法扩展了非稳态相对渗透率测试的适用范围,避免了JBN方法带来的大毛细数限制。
英文摘要：
Relative permeability curve calculating method from ID transient core flooding data under different capillarv number was proposed in this study using iTOUGH2,an inverse modeling software for imiltiphase flow in porous media.Relative permeability curve was calculated at the condition which capillary pressure curve is known and compared with the results obtained from JBN method.Using the inverse modeling method,capillary pressure and relative permeability curve were obtained simultaneously when capillary pressure curve was unknown also,and converging capillary number range for inverse modeling was discussed.
