通过生物表面活性剂(DSB)与化学表面活性剂重烷基苯磺酸盐ZW1、重烷基苯磺酸盐ZW2及α 烯烃磺酸盐(XT)的复配,对复配前后的三元复合驱油体系界面张力进行了研究。结果表明,生物表面活性剂DSB与重烷基苯磺酸盐ZW1和α 烯烃磺酸盐XT复配后可以显著降低三元体系的界面张力,与ZW2复配也可达到降低成本的目的。
Through the combination of biosurfactant (DSB) and chemical surfactants, such as heavy alkyl benzene sulfonate ZW1, heavy alkyl benzene sulfonate ZW2 and α-olefin sulfonate (XT), the ternary The interfacial tension of composite flooding system was studied. The results showed that the interfacial tension of ternary system can be significantly reduced by the combination of biosurfactant DSB with ZW1 and α-olefin sulfonate XT, and the cost reduction can be achieved by compounding with ZW2.
