摘要： 对研制出的复配稳泡剂泡沫体系，在80℃下开展了高盐对泡沫体系的稳定性和表观粘度影响的研究，并应用扫描电镜观察不含盐、含盐度为7.08×104mg/L和20.30×104mg/L的泡沫的微观结构，试图找到高盐增效性的作用机理；运用HAAKE流变仪研究了高矿化度泡沫体系的粘弹性。实验结果显示：泡沫体系具有高盐增强泡沫体系的稳定性和表观粘度的效应，同时，该泡沫体系还存在一个最佳抗盐度；扫描电镜显示高浓度盐、聚合物和表面活性剂之间形成了高强度的复合膜，从而增加了泡沫的稳定性；泡沫体系具有很好的粘弹性。首次对泡沫体系的高盐增效性进行了研究，丰富了泡沫体系的理论，具有一定的应用价值。

Abstract: Aiming at the combined foam stabilizer foam system which has been researched，the stability and apparent viscosity of the system，which is caused by high salinity，is researched at 80℃，and foam microstructure，which is nonsalt，7.08×104mg/L and salinity of 20.3×104mg/L respectively，is observed with SEM，as to obtain the mechanism of synergistic action.The viscoelastic behavior of foam system is studied with HAAKE rheologic apparatus.The results of experiment indicate in this foam system，there is the characteristic of high salinity increasing stability and apparent viscosity and the best antisaline concentration.The result of SEM indicates among high concentration salinity，polymer and surfactant formed histrength complex film is formed，which can increase the stability of the foam system greatly，and the foam system is of superior viscoelasticity.The synergistic action caused by high salinity is firstly researched in this paper，which enhances foam theory and is valuable.

Key words: Combination formunation, foam, high salinity, synergistic action, viscoelasticity
