摘　　要：页岩气储层的测井评价不同于常规储层。根据页岩气储层的特性,将常规储层的"岩性、物性、含油性、电性"四性关系研究,拓展为"矿物组分、储层物性、地化特性、含油气性、可压裂性、测井属性"六性关系研究。介绍了矿物组分的分析方法,给出了孔隙度、渗透率和饱和度的计算方法。对重要的地化参数,如总有机碳含量、镜质体反射率、热成熟度指数进行了研究,探讨了游离气和吸附气的计算方法及影响因素,分析了页岩的可压裂性,给出了测井属性的概念,以及测井属性对于页岩气测井评价研究的意义。Logging evaluation on shale gas reservoir is different from conventional reservoirs.According to the characteristics of shale gas reservoirs,this paper expands 'the traditional four parameters relationship' of lithology,porosity and permeability properties,hydrocarbon saturation and electrical property to 'six parameters relationship' of mineral compositions,porosity and permeability properties,geochemical characteristics,hydrocarbon reserve,rock mechanical property and logging attributes.The method for analysis of mineral composition is introduced and calculation of porosity,permeability,and saturation is given,the important parameters of the source rocks such as organic carbon content,thermal maturity index is discussed,the calculation methods and the influence factors of shale gas content are described,and the fracturing performance of shale gas reservoirs is analyzed.Finally,the concept of logging attributes and the significance of the logging attributes for shale gas evaluation are proposed.
