摘要
研究了疏水缔合聚合物／碱／表面活性剂三元复合驱体系与大庆原油形成低界面张力的特征。结果表明，在降低界面张力方面，碱与表面活性剂间存在显著的协同效应；疏水缔合聚合物具有一定的降低油水界面张力能力，其对三元复合驱体系的平衡界面张力影响不大，对体系的动态界面张力具有比较显著的影响。碱、表面活性剂质量分数对疏水缔合聚合物三元复合驱体系／大庆原油间界面张力有很大影响，碱和表面活性剂最佳质量分数分别为1．0％．1．2％和0．1％-0．3％。
The low interfacial tension characteristics between hydrophobic association polymer/alkali/surfactant three - element compound system and Daqing crude oil were investigated. The results showed that the alkali and surfactant had an obvious synergistic effect in lowering interfacial tension and that the hydrophobic association polymer had only obvious effects on the dynamic interfacial tension but had hardly effects on the equilibrium interfacial tension of the three - element compound system although it could lower oil - water interfacial tension to a degree. The mass fraction of the alkali and surfactant affected the interfacial tension between the three - element compound system and Daqing crude oil obviously and their optimum mass fractions were 1.0% - 1.2% and 0.1% - 0.3% respectively.
