Abstract: According to the discussion of the dynamic mechanism of the formation of the East China Sea shelf basin, the paper has further clarified the dynamic mechanisms of basin formation. By analyzing the characteristics of basin evolution under the control of dynamic mechanism, four control functions of tectonic evolution on hydrocarbon accumulation have been proposed in the paper:(1) the tectonic movements control the basin evolution and depression structure; (2)the tectonic movements control the basin subsidence and stratigraphic distribution center migration; (3) tectonic movements determine critical period of accumulation of hydrocarbon and the differences between hydrocarbon sub-zones; (4) the hydrocarbon accumulation and distribution is under the control of tectonic movement. Basin evolution and tectonic movements are the dominant factors in hydrocarbon accumulation, and the petroleum geology study combining with tectonic movement is the focal for hydrocarbon exploration in the southern East China Sea Shelf Basin.
