摘　　要：针对川南页岩气录井过程中存在的单项录井技术无法实现元素与矿物同时检测分析,以及现有录井技术难以直接获得岩石孔隙度参数的问题,现场采用RoqSCAN技术开展随钻样品的矿物、元素含量检测以及岩石图像分析,并对RoqSCAN技术在岩石组分、岩石图像方面的分析效果与ECS测井、XRF元素录井、岩屑成像录井进行了对比。结果表明岩石组分检测方面,RoqSCAN技术与ECS测井、XRF元素录井效果基本一致;岩石图像分析精度方面,RoqSCAN技术高于现有的岩屑成像录井技术。现场应用结果表明,RoqSCAN技术实现了岩石组分与岩石图像的集成分析,在页岩气勘探开发中具有较好的推广应用价值。In the process of shale gas mud logging in Southern Sichuan Basin,the single mud logging technology can not realize the simultaneous detection and analysis of elements and minerals,and the existing mud logging technology is difficult to obtain the rock porosity directly.In the field,RoqSCAN technology is used to detect the mineral and element content of samples while drilling and to analyze the rock image.The analysis effect of RoqSCAN technology in rock constituents and rock image is compared with that of ECS logging,XRF element logging and cuttings imaging logging.The results show that in terms of rock constituent detection,the effect of RoqSCAN technology is basically the same as that of ECS logging and XRF element logging;in terms of the accuracy of rock image analysis,RoqSCAN technology is higher than that of the existing cuttings imaging logging technology.The application results show that RoqSCAN technology realizes the integrated analysis of rock constituents and rock images,and has good application value in shale gas exploration and development.
