【 摘 要 】

Laifeng-Xianfeng Block whose licensee of exploration belongs to China Huadian Corporation, is located in the west of Hubei province, the eastern edge of the Sichuan Basin and close to the eastern Sichuan high steep fold belt. This block is a mountain landform, in which the geology conditions are complicated. Thus, this paper focuses on 11 two-dimension seismic data and one discovery well in this block. By jointing logging to seismic, the bottom interface of shale gas reservoir in Wufeng-Longmaxi Formation are determined precisely and this type of Formation is characterized by low frequency, strong dual phases, stable distribution, and can be traced in the full-region. Finally, the structure style and distribution of target formations are identified, on the basis of which the integrated evaluation of preservation conditions for shale gas syncline structure is carried out, leading to a selection of Lianghekou Syncline for the best exploration area, which lays a foundation for the future exploration and deployment of shale gas.
