【Abstract】 Chemical flooding is the main technique for improving oil recovery in current oil fields of China. With main effect factors of oil recovery as the entry points, we review the research advances of the conventional tertiary oil recovery techniques using different chemical flooding, such as surfactant, polymer and SP/ASP. It focus summarizes the latest progress of nanotechnology based on functional nanomaterials flooding, elaborating its EOR mechanism in enhancing oil recovery. Finally, aiming at optimizing the functional materials based flooding technology, some urgent problems and challenges in the research field are discussed, and the trend of development is proposed as well.更多还原
