摘要
地球物理测井作为一种重要的资源评价方法,在天然气水合物储层准确识别和精细定量评价中发挥着重要作用,并且随着以勘探天然气水合物为目的的钻井增多,日益受到重视。基于国内外地球物理测井技术在天然气水合物勘探中的应用,综述各种定性识别和定量评价天然气水合物储层的地球物理测井方法和技术,对地球物理测井方法进行全面了解和研究,有助于未来逐步探明天然气水合物的赋存情况,为今后对其进行合理开发打下基础,进而为国家建设提供充足的能源支撑。着重介绍了不同地球物理测井技术在天然气水合物储层定性识别和定量评价中的应用,并分析储层评价过程中的难点,展望今后的研究方向、思路和应用前景。
Geophysical well logging,as an evaluation method of important resource,plays an important role in accurate identification and quantitation of the nature gas hydrate reservoir.Besides,it is becoming more and more important with the increase of the number of drilling for gas hydrates exploration.Based on application of the geophysical well logging technology at home and abroad in natural gas hydrate exploration,the paper reviews all kinds of methods and techniques of qualitative identification and quantitative evaluation of natural gas hydrate reservoir geophysical well logging.It is helpful for the future exploration of gas hydrate occurrence to make a research of geophysical well logging method.It is also a basis for the rational development and provides sufficient energy for national construction.This paper mainly introduces different geophysical well logging technologies in application of natural gas hydrate evaluation,and shows the future direction of research,thinking and application.
