On the basis of the application of ant tracking technology in the lower-order faults interpretation and determining the structural stress direction of Funing sedimentary period according to the main fault strike in Zhenwu fault zone, the method of numerical simulation of tectonic stress field was applied to simulate the distribution of structural stress in Funing sedimentary period, and then the development law of the lower-order faults both on the plane and profile were predicted from the perspective of stress, finally, the prediction result was compared to the structural analysis result. The results show that the fault traces are clear and intuitive in the attribute volume obtained by using the ant tracking technology to explain the lower-order faults, the application is more effective than some other seismic attribute technology such as the coherence and variance technique. The minimum principal stress direction was nearly NW333°-SE153° in the west of Zhenwu fault zone in Funing sedimentary period. The development of the lower-order faults were mainly controlled by the minimum principal stress and shear stress, the minimum principal stress control the advantage area of the fault development, the plane shear stress control the planar distribution, the fault were developed with nearly EW strikes in sinistral shear stress area and nearly NE strikes in dextral shear stress area, the profile shear stress control the fault tendency, the fault were developed with N and W tendency in sinistral shear stress area and S and E tendency in dextral shear stress area.
