Abstract：At present, fautt interpretation methods can identify large scale faults, but cannot identify subtle scale faults, especially for minor fracture system due to low signal noise ratio of seismic data.An approach for fracture system fine characterization is proposed in the paper, which includes fauh image enhancement technology and the improved third generation of coherence technology.T he purpose of fauh image enhancement technology is to enrich fautt information and improve seismic data SNR at the same ttme.The principles of the fautt image enhancement technology and the improved third generation of coherent technology are introduced.High resolution and better continuity 3D seismic coherence can be acquired through seismic coherence.Applications in Luojia area of Zhanhua Sag prove the efficiency of this approach in fracture system identification.
