生物与化学表面活性剂复配体系的研究

Study on Built System of Biosurfactant and Chemical Surfactant

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。

The interfacial tension of three-nutrient compound based oil-displacing system were studied before and after built,through the compounding of biosurfactant DSB with chemical surfactant heavy alkyl benzene sulfonate ZW1, ZW2 and α-olifine sulfonate(XT). As a result, the interfacial tension of ternary system were evidently dropped after built of DSB with ZW1 and XT, and the cost were reduced after built of DSB and ZW2.
