It is very difficult to analyze each fault and results is bad. In order to find exploration prospect in the area, the paper described plane rollover faulting system existing in structural map by the aid of rollover anticline pattern on profiles, so that can illustrate regularity more clearly that the faults distribute on a plane. Combining fault distribution regularity on seismic sections and study of Eogene structure and reservoir-formed regularity in the area, the article pointed out that the turning position of large curvature in plane rollover fault system is favorable exploration strip, which made exploration direction of the area more clear. The correctness of the study has been proved by drilling results.
