摘要: 为了探索一种耐吸附、 低张力二元复合体系的界面特性, 利用T e x a s - 5 0 0型旋滴界面张力仪以及岩心 渗流装置, 进行了体系初始界面张力以及模拟地层渗流过程中动态界面张力的测定; 通过静态吸附实验明确复合体 系中活性剂吸附量以及吸附对界面张力影响。结果表明, 新型无碱二元复合体系界面张力在活性剂质量分数低至 0. 0 5%、 聚合物质量浓度高至25 0 0m g / L, 亦可形成1 0-3数量级; 活性剂吸附量较小, 一次吸附后各界面张力依旧可 以维持1 0-3数量级。动态渗流实验结果显示, 即使考虑吸附及稀释作用, 在距离模型入口端3 / 5处二元体系动态界 面张力依旧可以维持1 0-3数量级。

Abstract: In order to explore the binary composite system interface characteristics of adsorption resistance and low tension, Texas500 spinning drop interfacial tensiometer and core flow device were used to measure the initial interfacial tension and simulate dynamic interfacial tension.The effect of interfacial tension and adsorption capacity was confirmed through the static adsorption experiments. The results showed that the new Ecompound system interfacial tension of 10-3 orders of magnitude can also be formed when active dosage was as low as 0.05% and polymer concentration was up to 2 500 mg/L. Static adsorption proved that interfacial tension 10-3 orders of magnitude can be maintained when amount of adsorption agent was little after first adsorption. Dynamic flow experiment results showed that even considering absorption and dilution, dynamic interfacial tension of the binary system can still maintain a 10-3 orders of magnitude in 0.6 PV.
