摘要
结合国家“八五”科技攻关项目－大庆油田复合驱油体系的实际，利用试剂级药品，从理论上探讨了影响驱油体系界面张力的因素．结果表明，羧酸的皂化比是影响驱油体系与原油间界面张力的重要因素．油酸的皂化比为０．７５左右时，体系的界面张力最低；ＮａＣｌ浓度也显著影响体系的界面张力，所研究体系的最佳盐浓度为０．４％ＮａＣｌ；而ＨＰＡＭ的加入则有使界面张力升高的趋势．
It was been studied that various factors influence on interfacial tension (IFT) for oleate flooding system. The results show that the neutralized ratio of oleic acid and the concentration of NaCl have obvious influence on IFT of the system. IFT of system obtains minimum value when the neutralized ratio of oleic acid is equal to 0. 75 and the concentration of NaCl is equal to 0. 4%. The IFT tend towards rise in the presence of hydrolyzed polyacrylamide,especially had it present with NaCl.
