摘要
为提高化学驱油技术的使用效率,有效掌握表面活性剂的界面张力变化因素,开展了原油组分对表面活性剂界面张力的影响研究。应用原油分离提纯技术、GC-MS、红外光谱和核磁共振分析方法,从原油中分离出石油酸,分析其组分间的相互关系,总结界面张力变化规律。实验结果表明,原油组分中石油酸是影响界面张力的主要成分,其中异构脂肪酸是降低界面张力的重要贡献者。
The effect of oil components on interfacial tension of surfactants has been studied to improve the efficiency of chemical flooding.By applying the techniques of oil separation and purification,GC-MS,IR and NMR,the oil acid is separated from crude oil to analyze the interrelationship of the components and sum up the regularity of interfacial tension.Experimental result indicates that oil acid is the key component affecting interfacial tension and isomeric aliphatic acid is the key contributor to the reduction of interfacial tension.
