In Order tO study the sOlutiOn prOperties Of cOcOamidO prOpyl hydrOxy sulfObetaine ( CHSB) and sOdium alpha-Ole-fin sulfOnate ( AOS) cOmpOunded system, the surface dilatatiOnal viscOelasticity and fOam prOperty Of cOmpOunded system were characterized by interfacial rheOmeter and fOam scanner. And the flOw cOntrOl ability Of this cOmpOunded system was in-vestigated by fOam flOOding instrument. The results shOw that when the mass ratiO Of CHSB and AOS is 4 : 6, the surface ad-sOrptiOn amOunt Of the cOmpOunded system is the largest, and the average area Of the mOlecules OccupatiOn is the smallest. The surface dilatatiOnal viscOelasticity Of cOmpOunded system is better than that Of the single CHSB Or AOS. The elasticity Of the surface film fOr cOmpOunded system is dOminant. And the fOam stability Of the cOmpOunded system is imprOved signifi-cantly. The flOw cOntrOl ability Of the cOmpOunded system is better than that Of single CHSB Or AOS. The effect Of tempera-ture Or salt On cOmpOunded system is slight.%为考察磺基甜菜碱与烯烃磺酸盐复配体系的溶液性能,利用界面流变仪和泡沫扫描仪研究磺基甜菜碱复配体系的表面扩张黏弹性及泡沫性能,利用泡沫驱油装置测量磺基甜菜碱复配体系的流度控制能力。结果表明：磺基甜菜碱与烯烃磺酸盐的质量比为4：6,复配体系的表面吸附量最大,分子占据的平均面积最小；复配体系的表面扩张黏弹性好于单一磺基甜菜碱或烯烃磺酸盐的表面扩张黏弹性,复配体系的表面膜以弹性为主,且复配体系的泡沫性能明显改善；复配体系在多孔介质中的流度控制能力明显好于单一磺基甜菜碱或烯烃磺酸盐的；复配体系受温度或盐的影响较小。
