Abstract: The Neotectonic movement begun in the Miocene is divided into four episodes in Tarim basin, which have affected the petroleum accumulation and distribution in Bashituopu area since the Miocene. Based on the paleostructure restoration of this oilfield, integrated with the analysis of petroleum accumulation and distribution in the four episodes, it is suggested that in different episodes, the trap area, closure height and structural high will be changed in different degrees with the intensity of tectonic movements; in the same structural unit, different traps are of different development or changes, and accompanied with secondary migration and redistribution of petroleum. These characteristics in Bashituopu oilfield can be summarized as convergence and shift model for hydrocarbon accumulation, by which the formation and development process of the petroleum traps in this area can be studied as a guide for exploration and development of oil?gas accumulation zones that affected by episodic tectonic movements
