摘　　要：阜新盆地含油气地层为九佛堂组及沙海组三段的湖相泥岩,整个沙海组四段可作为区域性盖层,强调沙海组扇三角洲砂体有利于油气的运移和聚集,对储层、含油系统类型、盖层分布特征、生储盖组合类型、圈闭类型进行了分析,就油气开采规模做出评价,根据盆地内的油气显示情况提出了勘探建议。This paper argues that the oil- and gas-bearing strata in the Fuxin Basin are lacustrine mudstone of the Jiufotang Formation and the third member of the Shahai Formation. The fourth member of the Sha- hai Formation could be a regional caprock. The sandstone of the Shahai Formation formed in the fan delta system is good for the migration and reposition of oil and gas. The type of oil-reservoir and oil-bearing sys- tem, the spatial distribution of caprock, the source-reservoir-cap assemblage and the type of trap are also analyzed. This paper also estimates the scale of mining and provides some reconnaissance suggestions on the basis of the show of oil and gas in the basin.
