Abstract：The prediction of fractured buried hill reservoirs is one of the most important missions in nowadays exploration. We propose in the paper an integrated analysis flow, and apply it into the interpretation of fractured reservoir. This approach is dedicated to predict the major orientation and density of fractures in the survey, via matching and optimizing signal analysis of P-wave and relative wave impedance azimuth attributes responses. Meanwhile, compared with inversion responses, the fractured distributions in varied stress and structural conditions are built by fracture modeling of oil reservoir. Finally, the main control factors in different fractured zones of the survey are effectively summarized.
