摘　　要：分析了华北探区隐蔽油气藏类型及其分布特征。指出了隐蔽油气藏围绕生油中心分布 ,并提出其分布的有利区带 :箕状凹陷的陡坡带分布砂、砾岩体油气藏 ;洼槽带分布扇三角洲前缘砂体和浊积岩油气藏 ;斜坡带分布地层 -岩性油气藏 ;大断层下降盘负地形分布河道砂岩性油气藏 ;隆起区古山梁是潜山油气藏分布的有利区带。列举了两个隐蔽油气藏的勘探实例。总结了隐蔽油气藏的研究方法。The type and distribution characteristics of subtle reservoirs of exploration area in North China are analyzed. It is pointed out that subtle reservoirs distribute around oil generation center and following are the favorable belts: oilgas reservoirs of conglomerate body distribute at steep slope belt of halfgrabenlike depression, oilgas reservoirs of fan deltafront sand and turbidite developed at structural belt in sag, stratigraphiclithologic oilgas reservoirs developed at slope belt, channel sand lithologic oilgas reservoirs developed at negative landform of downthrow of major fault. Old mountain in uplift area is the favorable belt of buried hill oilgas reservoirs. Two exploration cases of the subtle reservoirs are listed. Research method for the subtle reservoirs is summarized finally.
