| Abstract: | This paper describes micro-fault interpretation by seismic attributes.Based on the high-resolution 3D seismic data,micro-faults with throw of 3~5m and structures with small relief can be detached effectively at the depth around 1300m using the forward model and different techniques such as coherence volume,curvature volume,structure-direction filter,time slice,large scale mapping,and so on.The results achieved have great geological significances. |

| Keywords: | curvature attribute coherence attribute micro-fault structure-direction filter fine structural interpretation structure with small relief |
