摘　　要：热采、气驱、化学驱仍是目前中外应用最为广泛的三大主要的提高采收率技术。随着提高采收率技术应用规模的扩大和逐步深入,传统的提高采收率技术面临的挑战越来越大。从新材料、新领域、新方法3个方面系统总结分析了提高采收率新技术研发与应用的进展。新材料方面关注功能性聚合物、二甲醚、纳米材料等;新领域方面关注残余油区CO_(2)混相驱、海上油田化学驱、非常规致密页岩油藏提高采收率;新方法注重技术复合化,例如碱-乳液-聚合物复合驱、声化技术、低矿化度水/表面活性剂交替注入。未来将以“低成本、绿色低碳、革命性突破”3个方向为核心探索新一代提高采收率新技术。Thermal recovery,gas flooding,and chemical flooding are widely used in China and abroad and are still the three main application technologies for enhanced oil recovery(EOR).With the wider and deeper application of EOR technology,traditional EOR technologies are facing increasing challenges.This paper systematically summarized and analyzed the progress in the development and application of new technologies for EOR from new materials,new fields,and new methods.Functional polymers,dimethyl ether,and nano-materials were highlighted as new materials;CO_(2) miscible flooding in residual oil resources,chemical flooding in offshore oil fields,and EOR methods in unconventional shale oil reservoirs were focused as new fields;new methods concentrated on technology combination,such as alkali-emulsion-polymer composite flooding,sonication technology,and low-salinity water-alternate-surfactant injection.In the future,we will explore a new generation of new technologies for EOR,with the core of“low cost,green and low carbon,and revolutionary breakthroughs”.
