摘　　要：对一系列磺酸盐双子表面活性剂的泡沫性能和油水界面张力进行了测试,并将磺酸盐双子表面活性剂与3~#甜菜碱表面活性剂和5~#黏弹性非离子表面活性剂进行复配,筛选出高稳泡超低界面张力泡沫体系。当磺酸盐双子表面活性剂DS14-2-14与3~#、5~#表面活性剂的质量比为5∶3∶2,复配表面活性剂的质量分数为0.4%时,最大起泡体积为500 m L,半衰期为26.84 min,平衡时的油水界面张力为8.9×10^(-3)mN/m。此时泡沫体系具有很强的耐温耐盐性和一定的抗油性。The foaming properties and the oil-water interfacial tension of a series of sulfonate gemini surfactants were studied,and one foam system of high foam stability and ultralow interfacial tension was chosen by optimizing the formula of the products that were prepared by mixing sulfonate gemini surfactants with3~betaine surfactant and 5~visco-elasticity non-ionic surfactant. The maximum foaming volume of the foam system is 500 m L,its half period is 26. 84 min,and the oil-water interfacial tension at equilibrium is 8. 9 × 10^（-3）mN/m when the mass ratio of sulfonate gemini surfactant DS14-2-14,3~betaine surfactant and5~visco-elasticity non-ionic surfactant is 5： 3： 2 and the mass fraction of the surfactant prepared is 0. 4%.This foam system has good heat resistance and salinity tolerance properties and is oil resistant to a less extent.
