摘　　要：深共晶溶剂(Deep Eutectic Solvent,DES)具有低饱和蒸气压、不易燃、不易爆、无毒、易降解、电化学和热稳定性好等优点。DES具有很好的表面活性,DES中的氢键网络与阴、阳离子表面活性剂具有很好的协同驱油作用。关于DES与常用表面活性剂的协同作用研究尚处于起步阶段,二者复配体系提高采收率(Enhanced Oil Recovery,EOR)机理尚不明确。在全面分析归纳总结胆碱基DES物理化学性质的基础上,探究了DES及其与阴或阳离子表面活性剂复配体系EOR机理,揭示了DES吸收二氧化碳机理,提出了DES在稠油油藏、低渗透油藏EOR以及碳捕集、利用与封存(Carbon Capture,Utilization and Storage,CCUS)中的应用建议。研究结果对DES在EOR和CCUS的应用推广具有重要的指导意义。Deep Eutectic Solvent(DES)has the advantages of low saturated vapor pressure,non-flammability,non-explosion,non-toxicity,easy degradation,good electrochemical and thermal stability,etc.DES has a good surface activity,and the hydrogen bond network in DES has a good synergistic oil displacement effect with anionic/cationic surfactants.The researches on synergistic effect of DES and common surfactants is still in the initial stage,and the mechanism of Enhanced Oil Recovery(EOR)of their compound system is still unclear.On the basis of comprehensive analysis and summary of the physical and chemical properties of choline-based DES,this paper explores the EOR mechanism of DES and its mixed system with anionic/cationic surfactants,reveals the mechanism of carbon dioxide absorption by DES,and puts forward some suggestions on the application of DES in EOR and carbon capture,utilisation and storage(CCUS)of heavy oil reservoirs,low permeability reservoirs.The research results are of significance in guiding the popularization and application of DES in EOR and CCUS.
