摘　　要：为得到适用于安塞油田长6油藏的耐高温高表面活性聚合物-表活性剂驱油体系,以黏弹性表面活性剂压裂液通用技术指标和复合驱用表面活性剂的技术要求为评价标准,通过对实验得到的适用于安塞油田长6油藏的驱油体系,从界面张力、乳化性能、驱油性能等几个方面在70℃和80℃高温下进行综合评价。结果表明:该复合驱油体系在高温下各项性能均符合标准,驱油效果良好,能有效提高采收率。In order to obtain a high-temperature-resistant,high-surface-active polymer-surfactant flooding system that could be employed for the Chang 6 reservoir in Ansai oilfield,an experimental flooding system suitable for the Chang 6 reservoir in Ansai oilfield was obtained through experiments.The general technical indicators of viscoelastic surfactant fracturing fluid and the technical requirements of surfactants for composite flooding were used as the evaluation criteria.Several aspects such as emulsification performance and oil displacement performance were comprehensively evaluated at 70℃and 80℃respectively.The results show that the performance of the composite flooding system meets the standard at high temperature,and the flooding effect is good,which can effectively improve the recovery factor.
