The Application of NMR Logging in Low Permeability Reserves Evaluation

GENG Bin(Geology Scientice Research Institute of Shengli Oilfield,Dongying,Shandong 257015,China)  
Because the pore structure of low permeability sandstone reservoir is complex,it is very difficult to recognize and evaluate the net pay using conventional logging.As a result,the evaluation of reserves have been greatly affected.Based on the NMR principle in Jishan low permeability sandstone reservoir,net pay have been identified using T_2 spectrum distribution and differential and shifted apectrum analysis,the physical properties cutoff of net pay thickness have been made through the pore structure research by NMR log,oil saturation has been interpreted using T_2 spectrum as well.Combined the NMR logging with the conventional logging,the precision of recognition and parameter explanation of net pay are enhanced evidently. So the difficuties of low permeability sandstone reserves evaluation have been solved.
