摘　　要：磺酸盐类阴离子表面活性剂在采油工业中应用广泛,其泡沫性能(起泡性和泡沫稳定性)对采收率影响很大。采用改进的Ross-Miles法对烷基碳数为14、16、18的脂肪醇聚氧乙烯(3)醚磺酸钠(CnH2n+1O(EO)2CH2CH2SO3Na,n=14、16、18)在不同条件下的泡沫性能进行了研究。结果表明,随着疏水基长度增加,表面活性剂起泡性降低,稳泡性增强;十四醇聚氧乙烯(3)醚磺酸钠起泡性最好,十八醇聚氧乙烯(3)醚磺酸钠稳泡性最优;随着温度的上升,3种表面活性剂起泡性增强,稳泡性降低。Surfactants of sulfonate series are extensively used in oil recovery industry, and its foaming properties have significant effects on oil recovery. The foaming properties of the polyoxyethylene fatty alkyl ether sulfonates （CnH2n＋ 1O （EO）2CH2CH2SO3Na, n = 14, 16, 18） were studied by modified Ross - Miles method under various conditions. The results showed that with the increase of carbon chain length of hydrophobic group, the foaming power of the surfactant decreases, on the contrary, the foam stability increases. The foaming power of C14H29O（EO）2CH2CH2SO3Na is the best, while ClsH37O（EO）2CH2CH2SO3Na has the strongest foam stability. Following the raising of temperature, the foaming power of the mentioned three surfactants increases while the foam stability drops down.
