【Abstract】 To solve the difficulty of deep well logging evaluation in Biyang depression, core experiment study has been conducted. A calculation model and lower limits of oil and gas reservoir parameters are determined for regional logging evaluation based on coring, oil testing data, and local experience. Suitable method for identifying local reservoirs is optimized. Comprehensive logging evaluation technology has been developed. The accuracy of logging evaluation is improved. It has been applied successfully in the exploration and production practice in Henan oil field. Meanwhile, the results indicate the significance of local experience and comprehensive evaluation ideas in dealing with the logging interpretation difficulties in low porosity and permeability reservoirs.更多还原
