Abstract：In order to better describe faults and fault system,by integrating 3d coherent data volume technique with 2nd generation Curvelet transform and based on excellent multi-scale characteristics and local filtering function,multi-scale coherent data volume analysis technique is developed in this paper,and the simple formula is also introduced.In Qu Bo Binding domain different reconstruction coefficients were derived,seismic data volumes in different frequency bands were calculated and by utilizing coherent volume algorithm the scaling coherent volumes were obtained.The simple method introduced in this paper was applied in real seismic data processing,the geological anomaly within certain frequency band was recognized,thus accurate interpretation can be easily conducted.
