Abstract：Faced with the issue traditionally taking 3-D seismic data as infill 2-D seismic data to conduct structural interpretation, the paper presented the methods and flow for interpretation of complex fault-block structure, established using cross-correlation envelope of synthetic seismograph with uphole seismic trace to solve the fine labeling method of time-shift and phase sweeping, implemented imaging of faults with different scale by using frequency-divided processing of seismic data and selection of dominant frequency, utilized color inversion to highlight faults and adopted multi-data volume to interactive interpretation.The method achieved good results when using it in interpretation of GB buried hill.
