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；CO2 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”.
