以大庆萨中二类油层三元复合驱强碱体系为研究对象，以二类油层的天然对接岩心和二类油层的天然去油油砂组成4个模型，绘制3种化学剂产出与注入相对浓度和注入孔隙体积倍数（C/C0~PV）曲线，采用突破注入量和等比浓度注入量差两个指标来描述三元复合驱油体系的色谱分离程度，通过岩心渗流实验研究了二类油层的三元体系色谱分离特性。实验表明，三元复合体系中3种化学剂在二类油层中存在色谱分离现象；HPAM最先突破，碱和表活剂随后一起突破；各类驱油化学剂间色谱分离程度从强到弱依次是：HPAM与表活剂、碱与表活剂、碱与HPAM；三元复合体系中碱、表活剂与HPAM 3种化学剂的突破时间随渗流距离增加而延迟，同时也增大了色谱分离程度；渗透率较小的二类油层比一类油层色谱分离作用更大。

The ASP flooding alkali system of Sazhong in Daqing was researched. 4models with natural butt core and natural oil removed sands were built. A curve of three chemicals on the relative concentration of outflow and injection with injected pore volume was drawn. The chromatographic separation degree of ASP flooding system was described based on two norms that are breakthrough injection volume and difference of geometric concentra-tion injection volume. The chromatographic separation characteristics of II reservoir's ternary system was re-searched by core flow experiments.
