Abstract：In Changyuan Oilfield,Daqing,well breakpoint data in dense well pattern is accurate and complete,and high-quality and high-density seismic data shows clear reflection characteristics of faults. With these favorable conditions,we propose in this paper a fault interpretation approach based on integration of well and seismic data. This approach includes:3D fault recognition,fault localization in space,fault illusion confirmation with dense well pattern,distinction between minor faults and lithologic change with seismic response,comparison of fault vertical throw,etc. The proposed approach is applied to several blocks of Changyuan Oilfield. Large fault spatial positions are accurately identified,fault illusions are clearly distinguished,and minor faults are clearly characterized. Based on the faults interpretation with the proposed approach,a directional well deployed by our proposition obtains very good results for remaining oil development.
