摘　　要：以新的成盆动力学机制研究成果为基础,结合对原型盆地类型及演化特征的全新认识,认为油气成藏受到了古构造演化的约束和控制。以苏北-南黄海南盆地的金湖、高邮、溱潼、海安凹陷为研究对象,讨论了构造演化对烃源岩分布以及对成烃演化史的制约和影响。对烃源岩分布的影响体现在改造和建设2方面;对成烃演化史的影响表现在对地温梯度、烃源岩埋藏深度和时间等因素的控制上。On the basis of research results of dynamic mechanism of new sedimentary basin formation and combined with the new understanding of prototype basin type and its evolution characteristics,it was considered that the hydrocarbon accumulation was restricted and controlled by the ancient tectonic evolution.By taking Jinhu Depression,Gaoyou,Qintong and Haian Depression in the South Yellow Sea Basin of North Jiangsu as the research object,the structural evolution of hydrocarbon source rock distribution and hydrocarbon generation and the restriction and control on the evolution history of hydrocarbon accumulation were discussed.The effect on the distribution of hydrocarbon source rock presents in reconstruction and construction,its effect on hydrocarbon generation history presents in the control of geothermal gradient,the buried depth and time of the hydrocarbon source rocks.
