摘要
为探索无碱二元驱配方的本质，寻找原油中对配方起主要作用的组分及含量，开展了原油组分对表面活性剂界面张力影响研究。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，从原油中分离制备出石油酸，表征了组分结构，研究了石油酸组分相互构效关系，并测量其与表面活性剂问界面张力。实验结果表明，该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。研究结果为无碱二元驱配方研制和推广应用奠定了基础。
In order to know the mechanism of surfactant-polymer flooding and the component and content in oil that react to the formula, effect of oil component on interracial tension of surfactant is studied. With oil separation and purification technique, GC-MS, infrared spectrum and NMR, petroleum acid is separated and prepared from oil, component structure is characterized, structure-activity relationship of component in petroleum acid is studied and interfacial tension between petroleum acid and surfactant is measured. The result shows that petroleum acid is the major component that affects interfacial tension and isomerous fat acid is the major contributor of lowering interfacial tension. The research lays a foundation for the development and application of surfactant-polymer flooding.
