Abstract: Combined with the field application cases at home and abroad in the past 20 years, the classification and oil displacement mechanism of nano-materials were analyzed and discussed. the technical advantages and problems of nano-materials in enhanced oil recovery were analyzed. The key factors and development direction of nano-materials applied in the field of enhanced oil recovery in the future were discussed and prospected. At present, the nano-particles used in enhanced oil recovery can be divided into metal oxides, organic particles and inorganic particles. The oil displacement mechanism of nano-materials is usually a combination of various mechanisms. Lamellar nano-materials have unique advantages. Hereinto, the new 2D intelligent nano oil displacement technology has been successfully carried out in many field tests and has great application potential in the field of enhancing oil recovery.

Key words: nano-materials, enhanced oil recovery, oil and gas field development, Black Card, chemical flooding, low-permeability oil reservoir
