Compared with the successful exploration of shale gas in the North America, the shale gas in the main hydrocarbon-bearing basins in our country is hosted in continental deposition. The mineral composition and sedimentary structure of shale are different between continental and marine facies. The characteristics of fracturing related to rock mechanics are the keys for the effective development of continental shale gas. The shale gas in continental facies mainly develops in mud-shale stones of lacustrine facies in the Lower Jurassic, the Sichuan Basin. Through a lot of old wells reviewed and reevaluated, we have acquired industrial shale gas in Jiannan and Yuanba areas in the east of Sichuan, showing a good potential. The controlling factors for the generation and accumulation of shale gas in the Lower Jurassic of the Sichuan Basin have been analysed, indicating that the lacustrine facies mud-shale stones are widespread in the Lower Jurassic and are outstanding for in-situ creation and in-situ accumulation. The TOC of mud-shale stones, the thickness of entrapped hydrocarbon and favorable preservation conditions all control the accumulation of shale gas in the Lower Jurassic. The contents of brittle mineral provide good conditions for massive hydraulic fracturing. Reasonable extract mode is the key to acquire industrial and long-term productions. According to shale gas evaluation and fracturing test, the shale gas in the Lower Jurassic of the Sichuan Basin is a favorable target for the breakthrough and built-up of shale gas in continental facies.%与北美在海相泥页岩中成功开发的页岩气相比,我国主要含油气盆地中的页岩气是以赋存于陆相沉积岩中为基本特点的,因此陆相层系也是页岩气勘探开发新的重要领域.但陆相与海相页岩中的矿物成分、沉积结构存在一定的差别,与岩石力学性质有关的压裂特征是制约陆相页岩气能否取得有效益的开发的关键.四川盆地下侏罗统陆相页岩气主要发育于湖湘泥页岩中.通过老井复查和重新评价,已在川东建南、元坝地区获得页岩气工业气流,展示了下侏罗统页岩气良好的潜力和可采性.对四川盆地下侏罗统页岩气形成条件和富集关键控制因素分析认为,下侏罗统湖相泥页岩分布广泛,具自生自储连续型气藏的特点.泥页岩有机质丰度、滞留烃的厚度和较好的保存条件是下侏罗统页岩气富集的主控因素；脆性矿物含量给大型水力压裂改造创造了较好条件;合理的试采方式是下侏罗统获得页岩气工业气流和长期稳产的关键；页岩气评价、压裂试验、测试证实,四川盆地下侏罗统页岩气是陆相页岩气突破和建产的有利目标.
