核磁共振测井进展

THE PROGRESS OF NUCLEAR MAGNETIC RESONANCE LOGGING

核磁共振测井是一种全新的测井方法,是对裸眼井测井解释和油气评价技术的重大突破,被国外石油界公认为过去二十多年中测井技术最重大的进步。本文阐述了核磁共振测井的发展历史,对目前使用的三种测井仪器:核磁共振成像测井仪、组合式脉冲核磁共振测井仪和大地磁场型系列核磁测井仪的原理和测井方式进行了说明,详细介绍了核磁共振测井方法在稠油油藏、水淹层、低阻油储层、天然气储层、碳酸盐岩储层,这些复杂储层评价中的应用,并对该技术未来发展方向,如随钻核磁共振测井技术,磁共振三维成像技术进行了展望,对有待解决的问题进行了讨论。

As a new logging method in oil industry,nuclear magnetic resonance logging, which is an important breakthrough in explaining well logging data and evaluating oil and gas, is regarded as the most progress in logging technology in the past twenty years. This article discussed the history of nuclear magnetic resonance,and introduced the principle of the instrument,such as MRIL,CMR and R MK923. Nuclear magnetic resonance logging can be used for explaining the complex reservoir, such as heavy oil reservoir, waterflooded reservoir, lowresistivity reservoir,gas reservoir and carbonate reservoir. At the end of this article,it discussed the future of nuclear magnetic resonance logging technology and some disadvantages shuld be improved.
