Abstract: The fine characterization of faults is of great significance for the potential exploration of remaining oil in complex fault block oilfields with ultra-high water cut. The fine characterization of faults in Cenozoic complex fault block oilfield in Zhanhua Sag of Bohai Bay Basin was studied through comprehensive analysis of correlation of well-seismic marker layer，identification of seismic event variation and validation of fault overlap model. The results show that：（1）The jointing relationship of rock formation on both sides of complex fault block reservoirs in Zhanhua Sag is complicated，the pattern of fault assemblage is varied and inherited small and micro faults are developed. The multi-technology fault interpretation method based on breakpoint identification，fault section interpretation，fault plane combination verification and fault space modeling have realized the fine identification，positioning and characterization of the faults，especially small and micro faults.（2）In the seismic profile of complex fault block reservoir in Zhanhua Sag，the variation phenomena of the events such as distortion，bifurcation and merging are important characteristics of the development of small and micro faults. The micro-twist， micro-distortion and micro-misalignment of the events are important basis for the fine identification and location of small and micro-faults.（3）The fine fault characterization can transform “blind area” and “fuzzy area” of the fault edge in the study area into potential area of remaining oil enrichment，which realized the expansion of new geological reserves on both sides of the fault. The fine fault characterization can optimize and improve the well pattern，increase the effectiveness of tapping potential and development，and also provided a scientific basis for further defining the remaining oil enrichment and distribution， adjusting the development well pattern and implementing precise development.

Key words: fine fault characterization, fault breakpoint identification, seismic event micro distort, remaining oil tapping, complex fault block oilfield, Cenozoic, Zhanhua Sag, Bohai Bay Basin
