英文摘要：

Fault is one of the major factors that control hvdroearbon accumulation in the Bohai Sea waters. Based on seismic interpretation and structural mapping, this paper focuses on the characteristics and tormation mechanisms of the Cenozoic faults in the Bohai Sea waters. In the study area, extensional and strike-slipping faults are the most predominant, and inverted faults are locally distributed. On plane view, most of the faults are of NE-, NW- or EW-trend, and the NE-trending taults mostly belong to the Tanlu strike-slip faut zone. While on sec- tional view, the faults occur as flower structures. The NW-trending faults are associated with the ZhangjiakouPenglai strike-slip fault zone, and constitute a conjugate shear faults system with the NE-trending faults during the neotectonic stage. The near EW-trending faults can be classified into two types according to their scale. The large-scale EW-trending faults, acting as the boundary faults between the salient and trough in the southern part, experienced the early extensional and late strike-slipping movements. They exhibit quasi-flower structures composed of major listric faults and shallow branching strike-slipping fautts on the section. The small-scale EWtrending faults are densely developed in the shallow strata, and they are mostly derivalive faults resuhed flom the strike-slipping movement of the Tanlu fault zone.
