Shale gas is a self-generated, self-stored, and self-enveloped unconventional natural gas gathered in the dark or high carbon mud shale. The shale gas exploration and development in North America has changed the energy structure of the world and has become extremely vital. Shale gas resource is rich in our country [1], especially the Paleozoic Marine black shale generated in the Sichuan Basin, which has a huge potential in terms of shale gas resource, and the dragon stream group of shale in the Lower Silurian series is considered as the most favorable layers for the development of shale gas. There is a humongous gas reserve in Neijiang-Luzhou-Yibin region. Shale gas exploration has gained high-yield commercial production in the Longmaxi Formation in the Changning-Weiyuan region of the Sichuan Basin [2] and Jiaoshiba region [3].
