摘　　要：为了进一步认识四川盆地涪陵地区陆相页岩气的勘探潜力,分析了该区自流井组不同层段泥页岩的沉积相分布、有机质含量及类型、成熟度、孔隙度、含气量、保存条件等页岩气形成条件,并与美国主要产气页岩进行比对后认为,涪陵东岳庙段位于浅湖—半深湖有利相带,泥页岩厚度大,烃源条件好,储集性较好,含气性好,且夹层含量低（泥地比＞80％）,埋深适中（2 500 ～3 100 m）,是该区目前最为现实的湖相页岩气勘探有利层系,建议加强专层勘探.In order to understand the shale gas exploration potential of Fuling area in Sichuan Basin, the formation conditions were analyzed such as sedimentary facies distribution, organic matter content and type, maturity, porosi- ty, gas content, preservation conditions and so on. By comparison with the major gas shale of America, it can be concluded that Dongyuemiao member is developed in favorable shallow lake to fairly deep lake reservoir zones with great thickness of mudstone and shale, good hydrocarbon source conditions, better reservoir conditions, high gas content and low interlayer content（mudstone thickness 〉 80% ）, moderate burial depth（2 500 ~ 3 100 m）. So it is the most favorable shale gas exploration strata of lacustrine facies in the area recently and further enhanced explora- tion of the formation is suggested.
