摘要: 主要针对胜利石油磺酸盆与助表面活性剂的二元驱体系中,研究其在油藏条件下,驱油体系的静、动态吸附规律与色谱分离特征。结果表明:胜利石油磺酸盐在低浓度下为线性吸附,最大静态吸附量为4.6mL,加入助表面活性剂可以有效降低其吸附量;石油磺酸盐与助表面活性剂存在一定色讲分离,且二元驭中聚合物的加入加大了这种色语分离效应。试验证明,只要适当增大注入液中活性剂浓度,二者的复配协同效应可以得到发挥。

Abstract:

The static and dynamic adsorption law and chromatographic separation character of flooding system of Shengli petroleum sul-fonate(SLPS) and assistant surfactant have been studied. Re-sups show that SLPS is linear adsorption at lower concentration,and maximum adsorption capacity is 4. 6 mg/L. The adsorption capacity has been reduced obviously when adding assistant sur-factant. There is chromatographic separation in some extant
when inject SLPS and assistant surfactant together, the effect of chromatographic separation is more obvious when adding HPAM in flooding system. According to the experiments, the coopera-five effect will exhibit by increasing the surfactant concentration of the flooding liquid.

Key words: petroleum sulfonate, dynamic adsorption, chromatographic separation, surfactant/polymer flooding
