Abstract: NuclearMagnetic Resonance mud logging(NMRmud logging) is a technique that mainly applies the CPMGpulse sequence to measure transverse relaxation time(T2) , its size and distribution in hydrogen pit that exists in rock samples, acquire reservoir's physical parameters timely and accurately while drilling.The feature of NMRmud logging is that the cutting analysis has its own particular characteristic,andis free fromthe limitation of sample types,moreover, the analysis speed is quick,and an analysiscan not only provide many parameters but gain precise analysisresults.NMRmud logging has been used for more than one year in Liaohe exploration area, playing an important role in assessing reservoir and interpreting oil, gas and water layers,having certain significance for exploration in oilfield.

Key words: NMRmud logging, reservoir physical parameter, interpretation of oil, gas and water layers;Liaohe Oilfield
