The organic-rich shale in Lower Silurian Longmaxi formation Sichuan Basin is marine sedimentary strata, and it has large thickness and rich resources. Therefore, it is one of the most important parts in unconventional oil and gas reservoir exploration. Eastern Sichuan area is located in high and deep structural belt, so influenced by the factors of deep-buried structure, intense transformation and fault development, organic-rich shale belts’ distribution is unclear (Fig.1).
