Abstract:Western Sulige gas field he8 segment, with complex lithology, physical properties, and resistivity curve shapes, the logging evaluation is extremely difficult. Having integrated NMR imaging logging, cores SEM, cores observation, gas test and production data, and eliminated the impact of fracturing, typical gas, gas-water and water layers are optimal selected, summed up the corresponding resistivity curve shape types, found gas, gas-water and water layers are bell-shaped, box and smooth fluctuations type, and these cause factors are analysed. Summed up a set of log interpretation method suitable for the region, drew a crossplot, combined with apparent water resistivity technique for high unmovable water saturation intervals, and achieved good results.
