强碱三元体系界面张力影响因素研究

摘要

Interfacial tension was an important indicator to evaluate ASP system.The ASP system in the surfactant concentration,alkali concentration,polymer concentration,water salinity and other aspects of system stability was researched.Under the condition of different surfactant and alkali concentration,the interfacial tension in ASP system firstly reduced then increased,salinity played a great impact role in the interfacial tension,the interfacial tension in the system 0.30%S（surfactant）＋1.2%A（alkali）＋1650 mg/LP（polymer）can achieve ultra-low within 90 days,and it had a good stability.%界面张力是评价三元复合体系的重要指标。从三元复合体系表面活性剂浓度、碱浓度、聚合物浓度、水质矿化度以及体系稳定性等方面进行研究,得出不同表面活性剂、碱浓度下,三元复合体系界面张力先降低后升高,矿化度对界面张力的影响很大。0.30%S（表面活性剂）＋1.2%A（碱）＋1650 mg/LP（聚合物）三元复合体系的界面张力在90天内都能达到超低,具有良好的稳定性。
