| 摘 要： | 通过对东海陆架盆地形成的动力学机制研究，分析了动力学机制控制下的盆地南部构造演化特征，提出构造演化对油气成藏的四个控制作用：（1）构造运动控制了盆地演化阶段与凹陷结构；（2）构造运动控制了盆地沉降中心迁移与地层分布；（3）构造运动决定了油气成藏关键时期和油气分带的差异性；（4）构造运动控制了油气聚集与分布。构造运动是盆地演化及油气成藏的主导因素，盆地构造演化结合油气地质综合研究是东海陆架盆地南部油气勘探工作的重点。

| 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. |
