传统的表面活性剂因其"不耐温、不抗盐且界面性能有限"已经不能满足三次采油(EOR)过程的需要.一种基于有机硅氧烷双封端剂双子型(Gemini)表面活性剂能够很好地解决上述问题,日益受到科学家们的重视.该文在前期工作的基础上,较系统地综述了用于合成新型双子型驱油用新材料中间体——有机硅氧烷双封端剂的研究现状与进展.重点介绍了驱油用新材料的重要中间体(活性基团封端剂)的设计、合成及性能,并对活性封端剂在驱油用新材料中的发展趋势进行了展望.
Traditional surfactant has limitation in enhanced oil recovery ( EOR) because of its natural thermal instability, high sensitivity to salt contamination and limited interface properties, whereas an organic siloxane double end-capping agent Gemini surfactant ( Gemini ) can well solve the above problem and has attracted considerable attention. In this paper, we systematically summarize the research status and recent progress of new material intermediates-organic siloxane double end-capping agent for synthesis of Gemini type oil displacement agents. We mainly discuss the design,synthesis and property of important intermediates for synthesis of new oil displacement materials ( several reactive end-capping agent) . Moreover,we forecast the development tendency of the active end-capping agent in the new oil displacement material at the end of the paper.
