摘要
By using the latest 3D seismic data,we described the space distribution of the Tan-Lu fault in the southern Bohai area and analyzed the evolution history and the influence to sedimentation and tarp formation combining the previous research achievements.The results showed that: in the southern Bohai area,flower structure and formation dag were revealed in the Tan-Lu fault and the salt activity was also a strong evidence for the strik-slip movement of the Tan-Lu fault in Cenozoic.The activity of the Tan-Lu fault had a significant impact on the evolution of the Laizhou Bay Sag,mainly reflected by the migration of sedimentary center.It also led to the formation of traps in both deep and shallow layers and most of the traps were faulted anticlines and fault blocks.
