在天然油砂模型上进行了三元复合体系的流动实验，研究了润湿性、渗透率、渗流距离对三元复合体系色谱分离的影响．结果表明：驱油过程中化学剂间存在色谱分离现象；水湿条件下三元复合体系的色谱分离程度比油湿条件下明显，碱和活性剂之间的无因次等浓距，水湿比油湿增加０．２４；聚合物和活性剂之间的无因次等浓距，水湿比油湿增加０．２６．渗透率越低、渗流距离越长，三元复合体系的色谱分离程度越明显．
The flow experiment of the ternary composite system was carried out on the natural oil sands model. The influence of wettability, permeability and seepage distance on the chromatographic separation of the ternary complex system was studied. The results show that there is chromatographic separation between chemical agents in the process of oil displacement; the degree of chromatographic separation of the ternary complex system under water wet conditions is obviously higher than that under oil wet conditions, dimensionless concentration between alkali and active agent, water wet 0.24 more moisture than the oil; a dimensionless concentration between the polymer and the active agent, water wetting increased by 0.26 over oil wetting. The lower the permeability and the longer the seepage distance, the more obvious the chromatographic separation of the ternary composite system is.
