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AS、AP反应液中存在的表面活性剂OP-10和水解聚丙烯酰胺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。当配好后的配方溶液中表面活性剂OP-10的浓度不超10μg/ml时,则表面活性剂对硅铝元素浓度测定的影响可以忽略。因此,在测定复合驱替剂体系反应液中硅铝元素浓度时,应尽量把聚合物和表面活性剂的浓度控制在10μg/ml以下。

Abstract: Concentration measurement of silicon and aluminum in reacting solution of combination flooding system is a key problem for studying chemical behavior of reservoir minerals in alkaline flooding system. The effect of surfactant (OP0) and hydrolyzed polyacrylamide-3430S (HPAM) on concentration measurement of silicon and aluminum have been investigated systematically. Results have shown that HPAM has no effect on the measurement of aluminum 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. The influence of surfactant on silicon and aluminum concentration measurement is very small and may be neglected when surfactant concentration is no more than 10μg/ ml. Therefore, the concentration of polymer and surfactant
should be controlled under 10μg/ml when measuring silicon and aluminum concentration in reacting solution of combination flooding system.

Key words: hydrolyzed polyacrylamide, surfactant, silicon and aluminum, concentration measurement
