| 摘 要： | 通过对苏北盆地盐城凹陷阜宁组烃源岩研究,确定阜二段为盐城凹陷最有利烃源岩,结合多项成熟度指标分析及阜二段顶部地震反射层构造图,明确了区内阜宁组烃源岩的成熟生排烃范围,同时结合相关储层横向、纵向上的研究,指出阜三段下部砂体是阜二段油气聚集的最有利层系,并认为盐城凹陷可能存在"下生上储"型和"上生下储"型两类油气成藏模式,最后指出靠近大断裂的深凹带是盐城凹陷最有利的勘探区域。

| Abstract: | The studies of source rocks from the Funing Formation in the Yancheng Sag of the Northern Jiangsu Basin have indicated that the 2nd member of the Funing Formation is most favorable for hydrocarbon generation. Maturity parameters analyses and structural diagram of seismic reflection on the top of the 2nd member of the Funing Formation have shown the maturity and expulsion ranges of source rocks in the Funing Formation. Meanwhile, through the studies of relevant reservoirs, it has been stated briefly that the bottom sand bodies of the 3rd member of the Funing Formation are most favorable for the accumulation of hydrocarbons which generate from the 2nd member of the Funing Formation. 2 hydrocarbon accumulation models may exist in the Yancheng Sag, including "bottom source and top reservoir"and "top source and bottom reservoir". Deep sags near to big faults are the most favorable targets for petroleum exploration. |
