摘要
在三次采油体系中,通过加入添加剂来改变被吸附体系的溶液组成,以期降低表面活性剂的吸附量。研究了醇、无机盐、AES、聚丙烯酰胺等添加剂对油酸钠在粘土矿物上吸附的影响,得出的结果对三次采油具有理论指导意义。
In EOR system, changing solution composition of adsorption system through adding additives is used to decrease the adsorption quantity of sufactant. In this paper, influence of additives including alcohol, mineral, AES, polyacrylamide on adsorption of sodium oleic on clay minerals is discussed.
