The history of exploration and production in North America has proved that shale gas is an unconventional resource with great exploration potential. Shale gas is a continuous accumulation of natural gas as well as deep\|basin gas and coal-type gas. Shale with high organic matter not only acts as source rock, but also gas-producing layer and cap rock. The geological and geochemical conditions of shale gas formation are different in different gas layers. The shale gas mainly consists in absorbed and free gas generated from biological function, thermal decomposition or mixing of both. So, the geological reserve of shale gas is rich. The main factors of gas accmulation are total organic carbon (TOC), type of organic matter, thermal maturity, porosity of gas producing layer, formation pressure and fracture, etc. In addition, the correlation of these factors should be paid attention. In Comparison with to shale-gas North America basins, two sets of high quality shale (i.e. Lower Cambrian Jiulaodong Formation and lower Silurian Longmaxi Formation) in Sichuan basin have good conditions of geology and geochemistry for shale gas accumulation. Therefore, it should be paid more attention to shale gas exploration and production in Sichuan basin
