摘要
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.
