| 摘 要： | 以砂性介质为研究对象,用砂芯漏斗法测定轻非水相液(LNAPLs)在地下渗流的毛细压力与饱和度的关系曲线,并采用Parker-Lenhard模型及Brooks-Corey-Burdine模型获取油水二相的相对渗透曲线,结果表明对于相同介质,VGM模型对油相的相对渗透率估计大于BCB模型所预测,且二种不同模型所获取曲线具有不同的等渗点饱和度和等渗点相对渗透率,VGM模型所获取等渗点渗透率比BCB模型所获取的值大0.04,建议在研究砂性多孔介质中LNAPLs的迁移问题使用BCB模型获取相对渗透率。

| Abstract: | The paper determined capillary pressure-saturation relationship curve with sandy funnel of light nonaqueous-phase liquids in coarse sandy medium,and get the oil-water relative permeability curve by Parker-Lenhard model and Brooks-Corey Burdine-model.The results show that for the same medium,the oil relative permeability which estimated by VGM model are bigger than by BCB model,and the curve have different isotonic saturation point and isotonic relative permeability.The isotonic relative permeability accesse... |
