摘要
目前,中国页岩气开发及储层评价工作正处于初步探索阶段。为有效利用地质及地球物理测井技术进行页岩储层评价,在前人研究的基础上,总结了页岩气储层的基本特征,优选确定了页岩储层评价的关键参数:TOC含量、矿物成分及矿物的脆性指数、储层物性及含气量。概括了页岩地层使用的测井系列、页岩气层的定性测井响应特征,详细论述了表征页岩储层特征的关键参数定量评价方法,从有机地球化学参数、页岩的矿物组分及脆性指数、页岩储层物性参数、储层含气性评价4个方面展开了深入论述。最后,探讨了页岩储层综合评价研究进展及中国页岩气储层评价存在的问题,为建立适合我国页岩气储层的综合评价方法,优选优质页岩富集区段提供依据。
At present, China＇s shale gas development and reservoir evaluation study is in preliminary stage. In order to make full use of geological information and geophysical logging technology to evaluate shale gas reservoirs, this paper summarizes the basic characteristics of shale gas reservoirs and chooses TOC con- tent, mineral composition, mineral fragility index, reservoir property and gas content as the key parame- ters for shale reservoir evaluation based on a large number of literatures. Then, the paper describes log- ging series, the qualitative logging response characteristics and the quantitative evaluation of the key pa- rameters of the shale gas reservoirs. Furthermore, the paper discusses in detail the organic geochemical parameters, mineral component and fragility index of shale, physical parameters of shale reservoir and gas content. Although comprehensive evaluation of shale gas reservoir has made great progress, there are still some problems in the shale gas reservoir evaluation in China. This paper provides the basis for the estab- lishment of the evaluation and classification methods for shale gas reservoirs in China, as well as the selec- tion of high quality shale gas layers.
