FAULT SYSTEMS AND CHARACTERISTICS OF THEIR CONTROLLING RESERVOIR FORMATION IN THE NORTHEAST CHINA

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.
