摘　　要：为了建立适用于页岩气评价的测井解释体系,对比分析了页岩气测井与常规测井的差异,选取国外页岩气勘探实例,说明了测井组合在识别含气页岩层上的应用,根据页岩气勘探需求,对页岩气储层测井评价方法进行探讨。结果表明:常规测井组合能够满足页岩气层的识别要求;传统测井与特殊测井系列组合可用于求取孔隙度、含气量等储集参数,还可用于估算总有碳含量(TOC)、成熟度指数等关键指标;一些特殊测井技术多用于裂缝的识别与岩石力学参数评价。常规测井与特殊测井各有优势,加强对常规测井与特殊测井结合应用的研究应是未来探索方向。In order to build logging interpretation system in the shale gas evaluation,the differences between shale gas logging and common logging were comparatively analyzed. By selecting an example of shale gas exploration,the application on identifying gas bearing shales was illustrated and the methods of logging evaluation of shale gas reservoirs were discussed. The results showed that the common logging method could meet the demand of identifying gas bearing shales,and the combination of common and special logging were available for calculating the reservoir parameters of porosity,gas content as well as some key factors like TOC,maturity index; the special logging technology were used for recognizing the fissures and evaluating the parameters of rock mechanics.Both common logging and special had their spectal advantages.To enhance the study of combined application of common and special logging should be the future direction.
