摘　　要：以十二烷基磺酸钠为例,考察了利用电位滴定方法分析ASP三元复合驱采出液中表面活性剂浓度时,pH值、盐度、聚合物含量、石油酸皂浓度等因素对分析结果的影响,研究出因石油酸皂和聚合物的存在导致结果偏高的消除方法,并对方法的检出限进行研究。该方法为ASP三元驱中十二烷基磺酸钠类阴离子表面活性剂浓度的分析提供了参考。Taking sodium dodecyl sulfonate(SDS)as an example,the influence of factors such as pH value,salinity,polymer concentration and petroleum acid soap concentration on the titration results of surfactant concentration has been investigated.The titration result is on the high side because of the existing of petroleum acid soap and polymer may.And a method to minimize the influence of petroleum acid soap and polymer on the titration results is developed.Besides,the method detection limit is also studied.This method provides a reference for the concentration analysis of anionic surfactants such as SDS in ASP flooding.
