Abstract: According to the 3D seismic interpretation in Pingbei area, reflection features of the chief interfaces of the area were elaborated. Based on the research of the seismic section, structural features of Tuanjieting fault-anticline, Baoyunting fault horst zone, Wuyunting, Kongqueting, and Laiheting fault blocks which formed and controlled by the faults of nose-like structures were analyzed. Areal distribution charactristics of different kinds of faults was portrayed and the structural evolution of this area was analyzed.
