APPLICATION OF CORE DATA PROCESSING METHOD FOR NMR MEASUREMENTS TO THE EASTERN DEPRESSION OF NORTH YELLOW SEA: APPLICATION OF CORE DATA PROCESSING METHOD FOR NMR MEASUREMENTS TO THE EASTERN DEPRESSION OF NORTH YELLOW SEA

NMR logging technology,due to its accurate measurement result and the advantage of detecting lithological texture without damage,is increasingly and extensively applied in oil exploration and development.In this paper,we focused on the core data spectral processing method of NMR taking the Eastern Depression of the North Yellow Sea as a case.Pretreatment,spectrum analysis and formation parameter method and process were discussed for the core data processing of NMR.Using the optimal solution spectrum method,we obtained the data of effective porosity,movable fluid porosity,bound water porosity and permeability of formation parameters.
