Tight sandstone gas reservoirs are playing an increasingly important role in the growth of reserves and energy supply. However, due to the complex geological conditions, there are still many unfavorable aspects of the engineering and technology needed for exploration and development, and various aspects of research are urgently needed. This paper describes the formation mechanism of tight sandstone, the division of oil and gas reservoirs and their characteristics. The typical examples of tight sandstone gas reservoirs are listed. The key technologies and existing problems in the future are outlined. This will be of great significance to exploration and development of tight sandstone gas reservoirs in the future Play an important guiding role.
