摘要
Based on the three dimensional seismic, drilling, and core data, the structural features of the Qingdong sag is analyzed. The results show that the structure features varied for each evolution stage of Paleogene. The basin is mainly controlled by the NW-trending faults from the deposit stage of Kongdian Formation to the later deposit stage of the 4th member of Shahejie Formation, however, the faults were scarce but large. During the deposit of the 4th member of Shahejie Formation, the sag was at a transitional period being characterized by composite basin pattern with NWW and EW-trending.
