Based on the traditional fine interpretation of seismic profiles, the recognition features and development rules of minor faults in Jiangjiadian area of Huimin Sag are summarized through method innovation and ant algorithm application. The restoration of balanced section contributes to a new understanding about the controlling factors of formation and forming period of minor faults. The formation mechanism is further verified by structure physical modeling. Many minor faults difficult to recognize by conventional seismic interpretation are identified by the above method during the process, and good application results are achieved.
