Abstract: In the Cenozoic，the intense strikeslip movement and complex evolvement of TanLu fault zone in Bohai Sea controlled the basin evolution and hydrocarbon accumulation.Through a comprehensive analysis of the seismic data and geological data in Bohai Sea，the TanLu fault zone in the region with a width of 50km，is divided into the East Branch and West Branch.TanLu fault zone is divided into the southern section and the northern section by ZhangjiakouPenglai fault.East Branch fault and West Branch fault of the southern section have very obvious strikeslip characteristics and East branch of the northern section has very obvious strikeslip characteristics，but the West branch has not.In the Paleogene，the East Branch and West Branch of the northern section were strikeslip movement，but late cutting of ZhangjiakouPenglai fault，resulting in West Branch strikeslip fault was blocked and abandoned，so the main strikeslip movement was on the East branch in the Neogene and the Quaternary.
