Abstract
Through the balance theory of capillary pressures and the empirical parameters of detected oil saturation of the fractures, on the basis of seperatively determined matrix oil saturation (is the functions of matrix porosity and reservoir height) and fracture oil saturation, the total oil saturation of dual-porosity media layers of the buried-hill oil reservoir is calculated; at the same time, integrating with the crossplot method of core, log, oil test, production performances and so forth, considering the lithological changed features of individual region and belt, oil and waterbearing interpretations and their detecting standards are qualitatively and quantitatively determined. Proven by the production performances, the interpretation precision is above 90%. The results show that the practical effects are good and the achievements have become the favorite method to recognize oil and water-bearing layers under the conditions of complex buried-hill oil reservoir system.关键词
