| 摘 要： | 通过一步反应合成了十四烷基磺基甜菜碱（BEl4）和十六烷基磺基甜菜碱（BEl6），并在高矿度条件下研究了所获得的甜菜碱型表面活性剂的油水界面张力性能。结果表明，所合成的烷基磺基甜菜碱型表面活性剂在高矿化度条件下均表现出良好的溶解性。质量分数为0．011％～0．182％的BEl4能使油水界面张力降低到10^-3mN／m量级，质量分数为0．012％～0．078％的BEl6可以在高矿化度下与原油达到超低界面张力。质量分数为0．039％的BEl6与质量浓度为800-2500mg／L的HPAM二元复合体系与原油在高矿化度条件下的界面张力也均可达到超低水平。

| Abstract: | Tetradecyl sulfobetaine（BE14）and hexadecyl sulfobetaine（BE16） were synthesized by one-step reaction, and the reducing oil/water interracial tension properties of BE14 and BE16 were investigated in high salinity water. It was found that BE14 and BE16 were found to be compatible with high salinity water, oil/water interfacial tension was reduced to 10 2 mN/m magnitude for 0.011 %-0. 182 0% （mass fraction） BE14 and ultra-low interfacial tension was reached for 0.012 %-0. 078 % BE16. Furthermore, it also exhibits ultra-low interracial tension for the mixed systems of 0. 039% BE16 and 800-2 500 mg/L HPAM. |
