    摘要:

    针对五里湾油田长6油藏地层水和脱水原油特征,双子表面活性剂A2可以实现超低界面张力。为了探索双子表面活性剂与原油组分间的构效关系,采用原油柱色谱分离方法对原油各组分进行了分离,获知了原油的基本组成。并对双子表面活性剂A2与原油各组分之间的界面张力进行了测定。结果表明,该表活剂在0.5-0.02%的浓度范围内均具有高的界面活性,可以令原油实现超低界面张力,证实了原油中非烃组分对超低界面张力的产生具有至关重要的作用,即双子表活剂与非烃组分之间存在协同效应。

    Abstract:

    In accordance with the characteristics of formation water and dehydrated crude oil from the Chang6 reservoir in Wuliwan,Gemini surfactant A2 can help to achieve ultra-low interfacial tension.In order to explore the structure-activity relationship between Gemini surfactants and the components of crude oil,crude oil components were separated by the method of the oil column chromatographic separation,following,the basic components of crude oil were learned.Then the interfacial tension between Gemini surfactant A2 and the components of crude oil was measured.The results show that,the surfactant shows high interfacial activity in the concentration range 0.5-0.02%,and can help to achieve ultra-low interfacial tension,and confirm that the non hydrocarbon components have important effect on the emergence of ultra low interfacial tension,namly there is synergistic effect between the Gemini surfactant and non hydrocarbon components.
