摘　　要：火山岩岩性、岩相是控制火山岩储层发育的重要因素,岩性、岩相识别是火山岩储层预测的重要基础工作之一,如何利用测井资料开展井点处火山岩岩相识别是地质和地球物理学家面临的一项挑战。针对某盆地深层火山岩地层,采用岩心刻度测井,利用钻井取心资料提取的岩性、结构、构造等特征标志,建立了常规测井识别火山岩成分、微电阻率扫描成像(FMI)测井识别火山岩结构构造的方法,最后利用测井识别的岩性、结构构造组合,建立了火山岩岩性识别的方法和技术流程。研究结果表明,常规测井资料结合FMI测井可以有效识别火山岩成分、结构、构造等地质特征,进而可以有效评价火山岩相分布。研究成果对于进一步加大火山岩勘探、测井资料标定地震具有重要的价值。Volcanic lithology and lithofacies were important control factors for controlling the development of volcanic rock reservoirs,their identification was one of the important and basic tasks for volcanic reservoir prediction.How to use well logging data to identify lithofacies in the borehole was the challenge for the geologists and geophysicists.According to the characters of a deep volcanic rock reservoir in a basin volcanic lithology,texture and structure were extracted based on the data of core description and well drilling.By using the method of core calibration logging,the identification methods of volcanic rock composition,texture and structure were established by using conventional logging and FMI respectively.Eventually the combination of the identified lithology,structure and texture are used to establish the method and technical process flow for the identification of volcanic lithology.The result indicates that the composition,texture and structure characteristics of the volcanic rocks can be identified by conventional logging combined with FMI.imaging logging it can be used for effectively evaluating the distribution of volcanic lithology The result has important value for the further volcanic reservoir exploration and logging data calibration.
