松辽盆地北部敖南地区扶余油层断裂与油气聚集的关系

The Relationship between Faults of Fuyu Reservoir and Oil Accumulation in Aonan Area in the Northern Part of Songliao Basin

断裂在敖南地区起着重要作用,既可以成为油气运移的通道,也可以为油气聚集提供遮挡条件。研究了敖南地区断裂的剖面和平面特征。扶余油层输导体系主要为斜坡断层-砂体"阶梯"状输导模式,在该输导模式框架内油气在侧向封闭性较好的断层附近的河道砂体内聚集成藏。

Faults play an important role in Aonan area,which only can be not channels for oil migration but also can provide barrier conditions for oil.Through the research,the characters of the faults both on profile and plane in this area have been understood.The major passage system in Fuyu reservoir in this area is the slop faults-sand step mode,in which framework the oil can be accumulating in sand body which near better lateral sealed faults.
