Study of the Algorithm for Singular Value Decomposition Inversion of NMR Logging Data Processing

LIU Hong-qiang,WANG Zhu-wen College of GeoExploration Science and Technology,Jilin University,Changchun 130026,China  
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.
