Abstract In this work, the efficiency of CO2-foam injection for enhanced oil recovery (EOR) is investigated. Six floods were performed on sand pack columns. Pure water injection, WAG injection and simultaneous injection of CO2 and surfactant solution with various concentrations were conducted. Notable difference was observed between oil production in secondary surfactant assisted WAG and other injection scenarios. The experimental work in this research shows that increase in concentration of surfactant in the injection process results in mobilization of more oil that may not have been achievable by using water flooding and WAG flooding methods individually.

与提高采收率应用相关的泡沫辅助水交替注气实验研究

摘要 在这项工作中,研究了二氧化碳泡沫注入提高石油采收率(EOR)的效率。在填砂柱上进行了六次驱替。进行了纯水注入、WAG注入和不同浓度CO2和表面活性剂溶液的同时注入。观察到二次表面活性剂辅助 WAG 和其他注入方案中的石油产量之间存在显着差异。本研究中的实验工作表明,注入过程中表面活性剂浓度的增加会导致更多的石油流动,而单独使用水驱和 WAG 驱油方法可能无法实现。
