Abstract

This paper reports the synthesis of AEC-9Na and its effects as an emulsifier on viscosity reduction of heavy oils. Williamson reaction was employed to obtain the emulsifier and its thermal stability was evaluated. The results showed that AEC-9Na can withstand a temperature of 300 °C, the viscosity reduction rate can reach greater than 99%, and it has high stability to calcium and magnesium salts. The interfacial tension of AEC-9Na on heavy oil reached 10⁻¹ level. Compared with the steam flooding, the flooding efficiency with the addition of 1.0% AEC-9Na was increased by 4.8%. The samples were examined microscopically and self-emulsification occurred.

摘要

本文报道了AEC-9Na的合成及其作为乳化剂对降低稠油粘度的作用。使用威廉姆森反应获得乳化剂并评估其热稳定性。结果表明，AEC-9Na可以承受300°C的温度，粘度降低率可以达到99％以上，并且对钙和镁盐具有很高的稳定性。AEC-9Na在重油上的界面张力达到10 ^-1级。与蒸汽驱相比，添加1.0％AEC-9Na驱油效率提高了4.8％。用显微镜检查样品并发生自乳化。
