由于所处大地构造单元、应力条件的不同,中国东北地区存在西部、中部和东部3个特征不同的断裂系统,导致其成盆、成烃和成藏的巨大差异,控制了西部海—塔盆地、中部松辽盆地、东部佳—伊地堑及周边盆地油气藏的形成与分布。通过剖析和比较海—塔盆地、松辽盆地和佳—伊地堑油气藏分布与断裂关系、断裂活动与油气藏成藏特征,指出了不同地区油气成藏与富集差异的原因是断裂系统及其控制作用不同,并提出东北地区下一步油气勘探的部署建议。

There are three fault systems with different features: the west,middle and east fault system in the Northeast China according to different tectonic settings and stress fields.This causes a great difference in the basin forming,hydrocarbon accumulating and reservoir forming in different regions.These fault systems control petroleum distribution in different regions of the west,middle and east fault system.By studying and contrasting the relationship between the petroleum accumulation distribution and fault action,this paper points out that different reasons for the petroleum accumulation are caused by fault system characteristics and these controlling factors.This paper also gives us the exploration proposes of Northeast China according to the synthesis analysis.
