摘　　要：涪陵页岩气田白马区块五峰组-龙马溪组一段页岩有效储层段总厚度在84 m~96 m,总体具有低孔、特低渗和高脆性矿物含量的特点。综合运用岩心观察、氩离子抛光-扫描电镜法、粘土矿物X射线衍射法、常规物性和氮气吸附测试分析方法,并结合白马区块五峰组-龙马溪组页岩储层评价标准,分析认为白马区块五峰组-龙马溪组一段页岩储层低孔、特低渗,有机碳含量、脆性矿物含量及含气量较高,主要为Ⅰ-Ⅱ类有效储层。The member 1 of the Wufeng Formation-Longmaxi Formation in Baima Block of Fuling shale gas field is characterized by low porosity,ultra-low permeability and high brittle mineralogy,with its effective reservoir thickness of 84m~96m.Based on core observation,argon ion polishing-scanning electron microscopy,X-ray diffraction of clay minerals,conventional physical properties and nitrogen adsorption analysis,it is concluded that the shale reservoir in the member 1 of the Wufeng Formation-Longmaxi Formation in Baima Block is mainlyⅠ-Ⅱtype effective reservoir because of its low porosity,ultra-low permeability,and high magnitude of organic carbon content,brittle mineral content and gas content in combination with its evaluation criteria.
