摘要：

The research, exploration and production of shale gas in China have made great progress during the past two decades. A series of innovative recognitions formed in the past time, such as the mechanism of marine shale gas enrichment in southern China, have supported the rapid development of shale gas. In 2023, China's shale gas production reached 250×108 m3, accounting for more than 10% of the total natural gas production. Thus, shale gas is a major contributor to China's additional gas production. Based on a comprehensive review on the history of research, exploration and production of shale gas in China, this paper summarizes the progress in some theories and technologies, including the organic-rich shale formation mechanism, the characteristics and genetic mechanisms of high-quality reservoirs, the source–reservoir co-evolution mechanism, the shale gas occurrence mechanism and gas content evaluation, the enrichment and high-yield mechanisms and evaluation technologies, the reservoir stimulation techniques, and the production technique. Additionally, the paper identifies the technical challenges and delineates four research directions (the enrichment and high-yield mechanisms of marine, continental and transitional shale gases, the methods for evaluating shale gas enrichment zones based on dynamic evolution process, the efficient development techniques for low-abundance shale gas, and the enhanced gas recovery (EGR) techniques. In light of the challenges confronted by commercial shale gas exploration and production in China, the paper recommends to carry out shale gas exploration and production from three aspects: new zones/areas, tapping the potential and increasing the reserves recovery in old areas, and EGR field tests. These efforts are expected to support the extensive and efficient exploration and production of shale gas in multiple fields and multiple layers, so as to effectively contribute to China's shale gas revolution in an all-round way and ultimately ensure the national energy security. © 2024 Natural Gas Industry Journal Agency.
