Abstract: In order to improve the logging accuracy of reservoir parameters, based on the geologic, core and well test data and rock-electrical characteristics of main reservoirs in the YD Oilfield, the positive and negative accumulation statistics method, oil and gas accumulation volume method and Pickett crossplot method were used to update the models of reservoir rock, mineral, porosity, permeability and saturation. The interpretation parameters of porosity, permeability and saturation in each zone were refined, especially for the cutoff value.The reservoir division and interpretation standards were rebuilt according to the latest parameters,and on this basis, the oil-water system in all target zones were redivided according to the SFT data. Well testing showed that the logging evaluation methods can be used to guide the comprehensive logging evaluation, reserve calculation and actual production in carbonate reservoir.
