Abstract: The article is based on fault interpretation skill and seismic attribute analysis technology, combined the different attribute which shows the positive response to micro-faults. Based on the steering coherence body to control the trend of regional fault and merging the dip-body, Azimuth-body, curvature-body which could meticulous describe the distribution of third or fourth level faults at the same time. In the end, according to the technical flow can figure out the plan and profile character of faults. There are five plane assembly style, including comb-type, anticomb-type, Cha I-type, Cha II-type, broom-type. There are seven profile assembly style, including reverse Y-type, Y-type, duplicate Y-type, X-type, broom-type, ladder-type, fork-type. This technique flow can provide certain experience and guide to the complicated rift basin which full of micro-faults.
