| 摘 要： | 研究了Gemini表面活性剂用于油田驱油体系的一系列应用性能:通过对热稳定性的考察,发现其初始分解温度均远高于地下油藏的温度75～90,℃;通过对界面张力的考察,发现Gemini H单剂在加入量为0.1%时,就可以使油水界面张力降到超低的10-3mN/m的数量级;而且Gemini H加入到聚丙烯酰胺溶液中不会使其黏度下降,在加入一定浓度的范围内,还会使溶液黏度略有提高,Gemini H完全可以作为驱油助剂的活性剂组分,用以提高原油的采收率.

| Abstract: | This paper studies some properties of Gemini surfactants applying to oil displacement system.By DTA analysis,this paper finds that the original decomposition temperatures of Gemini A-D are all far beyond the temperature of oil field underground.The interfacial tension between oil and water declines to 10-3mN/m at the concentration of Gemini H 0.1%.When adding Gemini H to PAM solution,we find that Gemini H doesn’t make the viscosity of the solution decline,however,in certain concentration range it makes the viscosity of the solution increase.The results show that Gemini H can be used as one component of oil-flooding agent to enhance oil recovery. |
