| 摘 要： | Gemini表面活性剂具有的优良表面活性,使之有望作为三次采油用的表面活性剂。用界面张力仪及HAAKERS600流变仪研究了非离子型Gemini表面活性剂的表面活性及流变特性。结果表明,25℃下,氧乙基数(EO数)分别为8,10,12的3种非离子型Gemini表面活性剂8-NP-8、10-NP-10及12-NP-12的临界胶束浓度(cmc)值分别为:0.99,0.15和0.032 mmol/L;非离子型Gemini表面活性剂的表面活性及cmc值受电解质的影响较小;氧乙基数为12的非离子型Gemini表面活性剂可以使亲水及亲油固体表面的接触角明显降低,水润湿性增强;非离子型Gemini表面活性剂溶液的粘度随剪切速率增加基本保持不变,呈现出牛顿流体的特性。

| Abstract: | The nonionic Gemini surfactant has excellent surface activity which makes it have prospect of broad application in EOR.The properties of nonionic Gemini surfactants,such as 8-NP-8,10-NP-10 and 12-NP-12,were researched by using HAAKERS600 rheometer and interface tensiometer to determine their surface activity and rheologic properties.Results indicated that their critical micell concentration(cmc) and minimun surface tension decrease as the number of ethoxy groups(EO) on Gemini surfactant increase from 8 to 1... |
