The tectonic evolution of the Tanlu fault zone occurred in the Paleogene and the Cenozoic,respectively,which resulted in a relatively complex tectonic evolution in the eastern part of the Liaohe offshore area.Based on the detailed explanation of seismic data,structural analysis and reservoir prediction,this paper analyzes the tectonic evolution process and the oil and gas migration and accumulation in the eastern part of Liaohe offshore area.The results show that the NE and the EW-induced MesozoicPaleozoic ...
