摘　　要：EMRT核磁共振成像测井仪是由中海油田服务股份有限公司研制的一种新型测井仪器,目前已商业应用。介绍EMRT工作原理、仪器的性能及与同类先进仪器性能对比情况,系统地分析了EMRT测井质量控制参数及现场应用情况。结合实例,对砂岩油藏的测量结果,进行了解释分析,表明EMRT测量评价解释符合地质客观实际,其性能指标达到了国外同类仪器水平,具有很好的应用前景。Magnetic resonance imaging logging tool（EMRT） is a modern logging instrument developed by COSL and has been com？mercial applied in many oilfields. In this paper, the operating principle, instrument performance and the performance comparison of similar advanced instruments of EMRT were introduced. The logging quality control parameters and the field application of EMRT were systematically analyzed. Combined with examples, the interpretation and explanation of the measured results of EMRT in sandstone reservoir were discussed at the same time. The results showed that measurement evaluation and explanation of EMRT were in line with the geological objective reality, and the performance index reached the the level of similar foreign instruments. Therefore, EMRT has great application prospect.
