基岩储层测井评价过程中，岩性识别是首先要解决的问题。梨树断陷基岩潜山地层的岩性十分复杂，既有变质岩，也有后期侵入的岩浆岩，又有碳酸盐岩，不同区块岩性分布不同，纵向上岩性变化大。利用录井、岩心分析、测井等多种资料，对岩石矿物成分、测井响应特征等进行分析，获知基岩岩石学特征、建立不同岩性与其测井响应特征关系、建立岩性识别图版，从而实现基岩岩性识别。

The lithology identification is the first important prob-lem in the process of the logging evaluation for the bedrock reservoir. The lithology of the bedrock in Lishu Fault Depression is complex, there are metamorphic rocks,magmatic rocks,and carbonate rocks. The lithology distribution is different in different blocks, the change of the lithology is big on the longitudinal.Using many datas of the logging, core analysis and well logging to analyze the rock mineral composition and the logging response characteristics, learning the petrological characteristics of the bedrock, building the relationships of different lithology and logging response, establishing the lithology identification chart, so as to realize the bedrock lithology identification.
