In order to further determine the distribution characteristics of the faults in Nanchuan district

we adopted the "three stories" structure for the fine structure interpretation

and combined with the technology such as the frequency division fusion

inclination of coherent

curvature

structure entropy

AFE and dip angle of curvature to predict the distribution of the fault. The application of the multiple attributes for the fault interpretation and the quality control of the fault section interpretation in 3D space improved the accuracy of the fault interpretation. There were 96 faults interpreted and closed in the district. It provides theoretical basis for oil and gas exploration and development.
