摘　　要：复合驱替剂体系反应液中硅铝元素浓度的测定是研究矿物在碱性驱替剂体系中化学行为的关键.系统地探讨了复合驱替剂体系反应液中存在的水解聚丙烯酰胺3430S(HPAM)和对硅、铝元素浓度测定的影响.研究结果表明:配方溶液中聚丙烯酰胺的浓度低于50μg/ml时,对铝元素浓度测定无影响,当聚丙烯酰胺的浓度低于10μg/ml时,对硅元素浓度测定的影响也很小.因此,在测定复合驱替剂体系反应液中硅铝元素浓度时,应尽量把聚合物浓度控制在10μg/ml以下.Concentration measurement of silicon and aluminum in reacted multiple flooding reagent solutions is a key problem for the study of chemical behavior of reservoir minerals in alkaline multiple flooding chemical system. Systematic investigations were made on the effect ofhydrolyzed polyacrylamide-3430s (HPAM)on concentration measurement of silicon and aluminum.The results show HPAM has no effect on the measurement ofaluminum when the concentration of HPAM in the formulated solutions is lower than 50μg/ml. The effect of polymer on silicon concentration measurement is little and may be neglected as long as the polymer concentration is lower than 10μg/ml . In all,the influence of polymer should be considered when measuring silicon and aluminum concentration. The concentration of polymer should be controlled under 10μg/ml.
