陕北地区侏罗系古地貌与油气成藏关系研究

RELATIONSHIP BETWEEN JURASSIC PALEOGEOMORPHOLOGY AND HYDROCARBON ACCUMULATION IN NORTHERN SHAANXI

摘要: 鄂尔多斯盆地侏罗系延安组具丰富的油气资源，多年来的勘探实践表明，侏罗系油气成藏除了与生油岩的分布、储集岩的分布和储集空间以及保存条件有关外，主要受古地貌条件的控制.

Abstract: Abundant hydrocarbon resources are reserved in Jurassic Yannan formationin Odors Basin. Exploration shows that the Jurassic hydrocarbon accumulation is mainly controlled by paleogeomorphologic conditions, with relations to the distribution of hydrocarbon source rock and reservoir rocks, accumulated space and save condition.
