摘要：

早白垩世青山口期末,松辽盆地经历了一次构造抬升运动.本文通过扶余等地区地层和侵蚀风化面分析,揭示了青山口组与姚家组之间为整合—假整合—不整合接触关系。葡萄花油层在构造抬升和剥蚀区扩大背景下生成,洪积扇、扇三角洲是其重要沉积类型。它们的大量出现,使岩性圈闭因素增多,有着较大的含油远景。

Abstract:

Songliao basin has undergone tectonic uplift at the end of Qinshankou during earlier Cretaceous.The changes in stratigraphic thickness,the erosion and weathering surfaces as well as absence of paleentolagical zones reveal that various types of contacts such as conformity, disnonfatmily and uncnnfoxmity, exist in the area between Qinshankou and Yaojia Foxmalions. The Putachua reservoir was formed under the influence of the extent of erosnon zones, which has resulted in the formation of impartant sedimentary fades, such as Proluvial fens and fan deltas etc. The development of great quantitirs of these facies sueely could enhance the availability of lithological traps and consequently shouid giver rise to more prospective areas for petroleum. The existence of odap zones in the west part of this basin favors the discovering of new reservoirs of unconformit type.
