Abstract：As low-grade faults have great influence on remaining oil distribution and injection-production relation,an accurate distribution of these minor faults is one of considerable interests in mature field development.After poststack seismic data are processed by high frequency enhancement and seismic attribute are obtained from ant tracking,we use a joint well-seismic interpretation to characterize low-grade faults with above 2-meter fault throw in the working area.This low-grade fault interpretation has been proven by well production information.Our study demonstrates that this joint well-seismic interpretation has great potential to improve the minor geologic body delineation for the mature field development stage.
