摘　　要：非常规油气资源已在全球能源结构中扮演着重要角色,页岩气作为保障我国能源可持续供给的重要选择,将对缓解我国目前及将来的能源供需矛盾起重要作用。页岩气是一种典型的"自生自储"成藏模式,重庆地区的下寒武统、下志留统龙马溪组、上二叠统等3套主力烃源岩不仅分布广泛,厚度大,有机碳含量高,成熟度适中,而且埋藏浅,是页岩气发育有利层位。此外目前直接的油气显示说明该地区的页岩气前景值得期待。Unconventional hydrocarbon resources play an important role in global energy structure. Shale gas as the important selection of energy resources sustainable supply protection in China will play an important role to relieve the contradiction between supply and demand of energy.The shale gas is a self-source and self-reservoir pool formation.There are three chief source rocks at Chongqing area, Lower Cambrian, Lower Silurian Longmaxi Formation and Upper Permian.They are favorable reservoirs for shale gas with extensive distribution,large thickness, high organic carbon content, etc.Through the oil and gas show, it can be seen the prospect of shale gas is valuable.
