摘　　要：对伊通盆地莫里青断陷基底变质岩储集层岩心进行观察,以地质认识为指导,充分利用常规及成像测井数据,系统总结该地区4种类型的变质岩岩性测井响应特征及有效性识别方法。利用孔隙度测井系列+成像测井,对变质岩岩性进行有效识别,提出了变质岩岩性测井多图版结合识别方法。利用成像测井+核磁共振测井,进行变质岩储集层裂缝识别、计算及有效性分析,最终识别研究区的变质岩优势岩相。对研究区多口井的测井资料进行评价,取得较好的评价效果,为该地区变质岩风险勘探提供技术支撑。Based on the observation of cores obtained from the basement metamorphic rocks in Moliqing fault depression,Yitong basin and guided by geological understandings,the paper uses the conventional logging and FMI logging data to systematically summarize the logging responses and its validity identification method of the lithologies of the 4 types of metamorphic rocks in the area.Effective identification is conducted by using porosity logging and FMI technologies and a method combined with multiple logging charts is proposed for the lithology identification of metamorphic rocks.The identification,calculation and validity analysis are performed for the fractures in the metamorphic reservoir by using FMI and NMR logging technologies,and finally the advantageous lithofacies of the metamorphic rocks are determined in the study area.Logging data from many wells in the study area are evaluated and relatively good results have been obtained,which provides technical support for the exploration of the metamorphic rocks in the area.
