摘要: 通过观察原油乳状液的表观黏度、界面张力和脱水率,研究了不同价态无机盐对石油磺酸钠(NPS)乳状液性能的影响。结果表明,一价无机盐NaCl和KCl在一定浓度范围内会增强NPS的作用;当NaCl和KCl的浓度分别为9 mmol/L和12 mmol/L时,可使NPS乳状液表观黏度分别升高224.03 mPa•s和122.48 mPa•s,界面张力分别下降10.6 mN/m和9.6 mN/m,脱水率分别降低10.7%和8.2%;随着二价无机盐MgCl2和CaCl2浓度的增加,NPS乳状液的表观黏度下降,脱水率上升,而界面张力呈先下降后上升的态势。

Abstract: The effects of different valence inorganic salts on the performance of sodium petroleum sulfonate (NPS) emulsion were investigated by observing the apparent viscosity, interfacial tension and dehydration rate of crude oil emulsion. The results show that NaCl and KCl can be enhanced the action of NPS in a certain concentration range. When the concentration of NaCl and KCl are 9 mmol/L and 12 mmol/L, NaCl and KCl can increase the apparent viscosity of emulsion by 224.03 mPa•s and 122.48 mPa•s, the interfacial tension can decrease by 10.6 mN/m and 9.6 mN/m, and the dehydration rate can reduce by 10.7% and 8.2%, respectively. As the concentration of inorganic salts MgCl2 and CaCl2 increases, MgCl2 and CaCl2 can decrease the apparent viscosity and increase the dehydration rate of NPS emulsion, while the interfacial tension decreases first and then increases.

Key words: Emulsion, Inorganic salt, Sodium petroleum sulfonate, Apparent viscosity, Interfacial tension, Dehydration rate
