MRIL-Prime核磁共振测井仪

MRIL-Prime nuclear magnetic resonant image logging tool.

MRIL -Prime是Halliburton公司推出的最新一代的核磁共振测井仪器。该仪器吸收了CMR和MRIL -C型仪器的优点 ,改进了其不足 ,采用 5个频带 9个不同的频率 ,一次下井可进行多种模式的测量 ,同时获得标准T2谱、移谱、差谱等信号 ,既提高了测井速度 ,又获得了更多的测井信息 ,同时数据精度也大大提高。文章介绍了该仪器的结构、主要技术指标、电子线路、电容和探头特征。

MRIL-Prime is the most new generation of nuclear magnetic resonant image logging tool manufactured by Halliburton. Up to 9 frequencies in 5 bands are used by the logging activations creating 9 independent volumes of measurements. This allows the tool to log at considerably higher speeds than previous versions of this tool such as the MRIL-C which only used 3 frequencies. It can get many different sets echos at one run,including standard spectrum,differential spectrum and shifted spectrum. The paper introduces the tool configuration,technological specification,the characteristic of electronic cartridge,capactor catridge and sonde,the measurement principle and practical implementation methods.
