中文摘要: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生成的一种新型测井仪器,目前已在国内、外油田商业应用。本文介绍了EMRT工作原理、仪器的性能及与国外同类先进仪器性能对比情况,给出EMRT在碳酸盐岩油藏勘探中的实际应用,分析了其质量控制参数、给出了EMRT 解释结论并与常规测井质量对比分析,在碳酸盐性油藏勘探中作用显而易见,油、水、气的T2谱峰特征明显,各种孔隙度计算准确。作为中国自主研发、具有独立知识产权的核磁共振测井仪EMRT性能指标达到了国外同类仪器水平,打破了国际公司核磁测井市场的垄断,提高了国内、外测井市场中的竞争优势
英文摘要:Magnetic resonance logging tool of EMRT (Elise Magnetic Resource Tool) is a new type instrument developed by China Oilfield Service Limited. It has been commercial applied in many oilfields such as Bohai Sea, South China Sea, Shanxi, Iraq and Indonesia and so on. In this paper, the basic principle and performance of EMRT is introduced. Compared with the similar instrument, such as MIRL-P, MRex and CMR, EMRT has achieved a similar level. This paper gives application of EMRT in prediction of carbonate rocks, and the analysis of quality control parameters, the interpretation and explanation of EMRT has been discussed at the same time. The T2 spectrum of EMRT in oil, gas and water has obvious characteristics and is different.Porosity calculated by T2 spectrum of EMRT is accurate. As China's independent research and development, EMRT with independent intellectual property rights breaks international technical monopoly, its advantage is obvious.
