对冀北地区中新元古界生、储、盖组合的分析,以及对该区化皮背斜的野外观察,认为由洪水庄组、铁岭组和下马岭组构成的地层组合是研究区最有利的生、储、盖组合。化皮背斜油气藏形成于三叠纪时期,背斜顶部铁岭组上段及以上大部分地层已遭受剥蚀,其实际是一个遭受破坏后残留的背斜古油藏。%Through the analysis of source-reservoir-seal assemblage of Meso-Neoproterozoic in northern Hebei,combined with the field observation of Huapi Anticline,it is considered that the combination of Hongshuizhuang,Tieling and Xiamaling Formation is the most favorite source-reservoir-seal assemblage in northern Hebei area.Huapi Anticline reservoir formed during Triassic period,and the upper Tieling Formation and above at the top of the anticline were eroded.Therefore,Huapi Anticline is an ancient anticline oil pool.
