松辽盆地层序地层格架及油气聚集规律

Sequence-stratigraphic framework and oil-gas accumulation rule in Songliao Basin.

本文通过对松辽盆地典型地区的解剖和分析 ,建立起松辽盆地上侏罗统—上白垩统地层格架 ,并按层序四分原则划分出体系域和准层序。对不同超层序发育特征进行了描述 ,并指出油气在不同体系域内的生储盖规律及其隐蔽性油气藏类型。

Through dissecting and analyzing the typical area in Songliao Basin,the paper created the Upper Jurassic-Upper Cretaceous stratigraphic framework of the Basin and divided it into depositional system tract and quasi-sequence according to the four-part divided principle.The paper also described development characters of different super-sequence and pointed out the rule of source,reservoir and cap which oil-gas is in different depositional system tract and its subtle reservoir type.
