白音查干凹陷油气聚集模式与勘探方向分析

Oil and Gas Accumulatin Model and Prospecting Direction Analysis for Baiyinchagan Depression

分析了白音查干凹陷的演化史和双层结构特征；阐述了环油源区分布的构造圈闭的形成机制；探讨了继承性发育的南部断超带和后期形成的北部断阶带的油气控制因素，建立了油气聚集模式。在油气评价的基础上明确了勘探方向和目标。

This paper analyzes evolution history and double-bed structural characteristics of Baiyinchagan Depression,and describes forming mechanism of the structural trap of the distribution around oil sources zone,discusses hydrocarbon control factors in southern fault overlaping zone subsequently developed and northern fault step zone late formed,constructs hydrocarbon accumulation model,based on oil and gas evaluation,clears definites prospecting direction and goal
