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。 At the end of the Early Cretaceous Qingshankou Period, the Songliao Basin underwent a tectonic uplifting movement. Based on the analysis of the strata and the erosion weathering surface in the Fuyu area, the relationship between the Qingshankou Formation and the Yaojia Formation was revealed as integration-false integration-unconformity . The Putaohua reservoir was formed in the tectonic uplift and erosion area expansion. The alluvial fan and fan delta are the important sedimentary types. Their large number of occurrences have increased the number of lithologic traps and have a larger oil prospect.
