摘要：1.Objective The Xianfeng area in Hubei Province is located in the central anticlinorium of the fold belt in western Hunan-Hubei,with a stable tectonic structure.It was in a deep-water shelf sedimentary environment from Wufeng period of Late Ordovician to Longmaxi period of Early Silurian,contributing to the formation of organic-rich shale in this area(Li B et al.,2016;Zhang H et al.,2019;Wu X et al.,2019).The well E Feng Di 1(Well EFD1)was drilled in Xianfeng area in the south of the central anticlinorium by preliminary geological survey and favorable shale gas areas optimization.During the drilling,shale gas was discovered from Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation(Wufeng-Longmaxi Formation).The geological conditions for shale gas enrichment were further defined through the analysis of the data obtained from the well drilling,well logging,and sample testing.The discovery will provide an important basis for further exploration and development of shale gas in this area.
