| 摘 要： | 化学驱所用的常规表面活性剂在高温高盐油藏中的应用受到限制,这主要是常规表面活性剂在高温高盐油藏条件下与钙离子产生相分离而失去表面活性所致,因而研究了在高温条件下钙离子对SDBS(十二烷基苯磺酸钠)胶束溶液的影响,旨在分析钙离子与常规表面活性剂的作用机理.当加入的钙离子浓度较低时,钙离子部分在胶束上结合,部分游离在溶液中... |

| Abstract: | The application of conventional surfactants in chemical flooding was limited in high temperature and high salt reservoir,the main reason was that the reaction of conventional surfactants with calcium ions produced phase separation in high temperature and high salt reservoirs,then surface activity of surfactant was lost.The effect of calcium ion on SDBS's micelles in high temperature was studied to analyze the interaction mechanism of calcium and conventional surfactants.The results show that when the concen... |
