Review and prospect on NMR logging application in Shengli oilefield

ZHAO Wen-jie1,TAN Mao-jin2(1.Institute of Geology and Geophysics,CAS,Beijing 100029,China;2.College of Eearth Science,Graduate University,CAS,Beijing 100049,China;3.Shengli Well Logging Company,SINOPEC,Dongying 257096,China)  
By right of new theory,Nuclear Magnetic Resonance(NMR) logging provides an abundant of information and response relationships,and gives good solutions to basic problems of formation evaluation.Since NMR Logging was introduced in 1996,Shengli Oilfield has accumulated ten-year′s experiences.The development of NMR Logging experiences three phase: probing phase,studying and applying phase,and improving and elevating step.In first phase,reservoir identification and petrophysics parameters calculation is predominant.Second step is as fluid typing and pore structure,and now NMR Logging application has enter the third phase,the target in which is geology application pointing to exploration problems.NMR Logging technology has become indispensable means of elevating exploration benefit,NMR logging has played great roles in reservoir classification,parameter calculation and fluid typing,especially in difficult reservoirs for conventional logs such as low resistivity/low difference resistivity,low porosity and low permeability and complex reservoirs.
