Abstract: Formed in Neozoic, the Yitong Basin is a channel strike-slip fault basin in the north of the Tancheng-Lujiang Fault Belt. It locates in Jilin province and has undergone regional structural impacts which originate from the Tancheng-Lujiang Fault Belt and the West Pacific Plate. The tectonic evolution of the basin can be divided into 3 stages including early inclined stretch, middle continuous strike slip, and late structural reversion, resulting in important controlling effects on petroleum accumulation. The influences of structure on deposition and accumulation have been studied based on the tectonic style and evolution process of the basin. It has been concluded that the early inclined stretch of the channel strike-slip fault basin is favorable for the generation of source rock and reservoir while the late structural reversion is favorable for the accumulation of oil and gas pool.
