In order to find potential exploration areas in this area, this paper describes the plane rolling fault system existing in the tectonic map of this area by means of the rolling anticline pattern in the section, so as to clearly reveal the regularity of the distribution of many faults in the plane. Based on the distribution characteristics of the fault system on the seismic section, the study on the tectonic and reservoir-forming laws of the Tertiary in this area shows that the turning point of the high curvature of the plane rolling fault system is a favorable prospecting zone, making the exploration direction of the area clear The The drilling confirmed the correctness of the conclusions of this study.
