摘要
测定了重烷基苯磺酸盐溶液与大庆原油间的动态界面张力 ,考察了NaOH、Na2 CO3 、部分水解聚丙烯酰胺(HPAM )和重烷基苯磺酸盐对动态界面张力的影响。结果表明 ,在大庆采油四厂原油ASP驱中 ,选用NaOH作碱剂容易产生低界面张力 ;当NaOH的浓度在一定范围内时 ,大庆采油四厂原油与重烷基苯磺酸盐体系间的界面张力能够达到超低值 ((10 -2 mN/m) ;NaOH对产生低界面张力的作用比HPAM和重烷基苯磺酸盐更显著。重烷基苯磺酸盐具有优良的表面活性 ,有望成为较理想的复合驱用表面活性剂。
The dynamic interfacial tension (IFT) between heavy alkylbenzene sulfonate and crude of Daqing oilfield was measured using the spinning drop tensiometer. The effects of concentrations of NaOH, Na 2CO 3, HPAM and heavy alkylbenzene sulfonate on the dynamic interfacial tension were discussed. The results indicate that the super low values of dynamic interfacial tension(lower than 10 -2 mN/m) between the heavy alkylbenzene sulfonate and the crude of Daqing oilfield can be reached, when the concentrations of alkaline are in a certain range. The influence of concentrations of NaOH on getting the low values of IFT is obviously greater than that of hydrolytic polyarylamide (HPAM) and heavy alkylbenzene sulfonate. The heavy alkylbenzene sulfonate has a good interfacial activity and may be used as a surfactant for ASP flooding.
