Abstract
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.关键词
