Abstract：The V field is a mature oilfield with multi-target stratum and sandstone-mudstone interbedding. The lack of porosity logging data in most wells is its typical feature. Because sedimentary environment, lithology and petrophysical property are different in different formation, the method of establishing reservoir parameter interpretation models for different logging suit and different formation is viable. According to core analysis data, the relationship of core porosity with density, spontaneous potential amplitude difference and gamma are studied respectively on the basis of logging data preprocess, and the relationship of core porosity with core permeability for each zone are also studied. Based on porosity and permeability interpretation model of each zone, the reservoir parameters of each zone are calculated accurately for every well in the V field. It lays the foundation for quantitative researches on reservoir geology and reservoir adjustment plan.
