摘要: 利用稳定性分析仪(LUMisizer-LS610)研究胜利原油乳状液的稳定性和粒径的变化规律,考察了乳化剂质量分数、油水体积比、温度及电解质对乳状液的稳定性和粒径的影响。结果表明,原油乳状液稳定性随乳化剂质量分数增大而增强,而液滴粒径则呈相反的变化趋势;乳状液中油相所含比例越大,乳状液越稳定;温度升高,虽然会增加乳化效果,但也同时破坏了乳状液的稳定性;电解质可以增强乳状液的稳定性,降低粒径。

Abstract: The stability of emulsion of Shengli crude oil and variation of drop size were investigated using LUMisizer-LS610. At the same time, the influences of the emulsifier concentration,the wateroil ratio, temperature and electrolyte on the stability of emulsion and the drop size were also explored. The results show that the higher emulsifier concentration is, the smaller the drop size would be and the more stable crude oil emulsion is. The greater the proportion of oil phase in emulsion, the more stable the emulsion is. As the temperature increases, the good emulsified effect is obtained, however, the stability of the emulsion is reduced. The electrolyte can enhance the stability of the emulsion and reduce the drop size.

Key words: Emulsion, Stability, LUMisizer, Integral transmission, Drop size
