摘要
核磁测井资料的处理与解释是核磁测井技术的关键,也是其应用的难点所在。介绍了利用奇异值分解法对回波串进行处理,求得最小二乘意义下的最优解,进一步得到关于孔隙度分布的T2谱。并利用T2分布谱对实际地层进行分析,区分油、气、水层。
Nuclear magnetic resonance(NMR) logging data process and interpretation is the key to nuclear magnetic logging technology,but also the difficulty of the application.This paper introduces the use of the singular value decomposition method to echo train processing.And get the least-squares sense optimal solution,further on the porosity distribution of T2 spectrum.Using T2 spectrum distribution to analysis the actual stratum,and distinguish between oil,gas and water layer.
