Recently, "Science China Earth Sciences" published an article in the form of a cover article in the form of an academician of the Chinese Academy of Sciences, a researcher at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences Chen Xu, etc., and the China National Petroleum Institute, the South Corporation, the Sinopec Research Institute, and the Southwest Branch. The paper entitled "The gradual and progressive pattern of black pen and stone shale of the Silurian Longmaxi Formation in the Sui area" co-published by young scholars of other institutions has attracted the attention of peers in the petroleum geological community in China. Based on the outcrop and drilling materials from Weibei to Huayingshan, the study clarified the four distribution corridors of the black shale at the bottom of the Longma River and proposed the progressive development of the black pen-stone shale from south to north. The model demonstrated that the Chongqing to Changning Corridor is the most favorable area for shale gas in the black shale of the Longmaxi Formation in China. At the same time, in combination with the depth of zoning model, the relationship between the depth of zoning and the favorable stratum of shale gas is explained. The study also provided a good example of the deep stratigraphy of the Silurian stratum. The study was funded by the China National Academy of Sciences’ Strategic Pilot Science and Technology Project and the National Natural Science Foundation.
