Abstract: Based on study of reservoir lithology, poroperm characteristics, electric properties and oil - bearing properties and their relationships, logging interpretation models for lithology and poroperm parameters of the lower permeability reservoirs in the second member of Hetaoyuan Fm in Dongzhuang - Beimazhuang area of Nanyang depression are built by using " core calibrating log" method. Error analysis shows that the accuracies of these models are high. These models provide a basis for secondary processing of digital logging data and study of reservoir heterogeneities.
