本文报导了用于孤东油田馆5~(2+3)层复合驱油试验的ASP体系与原油间界面张力的研究结果。在ASP复合驱油体系中,碱A和表面活性剂S在降低界面张力上有协同效应,聚合物P的影响很小。在单一A和A+S体系中最佳碱浓度为0.2％和1.5％(Na_2CO_3)。1.5％Na_2CO_3+0.4％OP-10体系有最佳界面特性。
This paper reports the results of the research on the interfacial tension between ASP system and crude oil for 5 ~ (2 + 3) composite flooding test in Gudong reservoir. In the ASP composite flooding system, alkali A and surfactant S have a synergistic effect in reducing the interfacial tension, and the influence of polymer P is small. The best alkali concentration was 0.2% and 1.5% (Na_2CO_3) in single A and A + S systems. 1.5% Na_2CO_3 + 0.4% OP-10 system has the best interface characteristics.
