摘要：
China was one of the first countries in the world to discover tight sandstone oil. Early in 1907, tight sand oil was discovered in the Triassic strata by the Well Yan 1 in the Ordos Basin and in 1989, a giant tight sand gas field of Jingbian was found in the Carboniferous- Permian strata in this basin. From then on, tight sand oil and gas fields were successively explored in various basins such as Sichuan, Junggar, Songliao, Bohai Bay, etc. In conclusion, tight sand oil and gas is abundantly stored in multiple formations and layers in largeor medium-sized basins all over China, of which tight oil reserves were estimated to be 28-30 billion tons while tight gas 66-70 trillion m3. This can be just proved by the recent rapid increase of both explored reserves and productivity of tight oil and gas. In view of this, an overall study was conducted on the geological settings, pooling conditions, the main controlling factors and indexes of "sweet spots", and distribution patterns of tight sand oil and gas reservoirs. Besides, such issues were discussed as reserves potential, potential challenges, etc. To sum up, with mature exploration and development technologies, tight oil and gas will be the first choice in the development of more unconventional hydrocarbon resources in China. © 2016, Natural Gas Industry Journal Agency.
