摘要
大庆原油与ASP三元体系间的界面张力有着多种影响因素,利用Tx500c型界面张力仪等研究界面张力随碱浓度、表面活性剂浓度、聚合物浓度、温度及碱类型的变化,结果表明除个别由于矿化度等问题影响出现的跳点外,界面张力随表面活性剂和碱浓度的增大而减小;随聚合物浓度的增加先增大再减小又增大;随温度的升高而降低;弱碱降低界面张力的效果好于强碱。
There are many influencing factor between the crude oil of Daqing oil field and ASP solution. By using Tx500c to measure the changing of interfacial tension with the concentration of alkali, surfactant, polymer and the temperature, we found that interracial tension decreases with the increase of surfactant and alkali concentration, with the increase of polymer concentration first increases and then decreases and increases; interracial tension decreases with increasing temperature： the reduction effect of Na2CO3 is better than that of NaOH.
