通过对苏北盆地溱潼凹陷新生代侵入岩展布、蚀变带储层以及时空配置关系的分析，探讨了其成藏机理和模式。该区侵入岩形成时间为始新世三垛运动时期；侵入岩纵向上以顺层侵入和穿层侵入展布为主，平面上以串珠状展布；岩浆侵入加速了烃源岩热演化进程，对围岩蚀变可形成良好储集空间，在上拱应力作用下，结合上部沉积岩，形成系列相关油气圈闭。岩浆侵入演变过程对溱潼凹陷油气聚集成藏起到了重要作用。

The time and space relationships between Cenozoic intrusive rock distributions and metamorphic zone reservoirs in the Qintong Sag of the Northern Jiangsu Basin were analyzed, and the corresponding accumulation mechanisms and patterns were discussed. The rock intrusions started during the Sanduo Movement of Eocene. Vertically, there were bedding intrusions and cutting-bedding intrusions. The intrusive rocks distributed like bead strings on plane map. Magma intrusions accelerated the thermal evolution of source rocks, and metamorphisms formed favorable reservoir spaces. Affected by up-arch stress and upper sediments, a series of related hydrocar-bon traps was formed. The evolution of magma intrusion played an important role in the hydrocarbon accumulation in the Qintong Sag.
