Abstract: The exploration in new series of strata and new area of Bohaiwan Basin is concisely reviewed and the petroleum geological conditions are analyzed.It also pointed out that abundant hydrocarbon resources are present in the new series of strata and new area.The properties of traps,sediments reservoirs and the principle of hydrocarbon accumulation are confirmed.The types of traps in deep zone of Eocene are various,and the exploration areas are extensive.There are abnormal porous and secondary pore developed zones in the reservoirs.The marine carbonate rocks which can generate hydrocarbon has been verified,and excellent reservoir formations can be formed in some areas.The theory of low matured hydrocarbon has been used to guide our search for hydrocarbon resources in shallow formations.Bohaiwan Basin has abundant hydrocarbon resources and good geological conditions,which provide a hopeful prospect with continuing enhanced exploration.

Key words: Bohaiwan Basin, structure, sediment, reservoir property, hydrocarbon prospect

摘要： 回顾渤海湾盆地新层系新领域勘探简况,分析了新层系新领域的石油地质条件.指出新层系新领域油气资源丰富,论证了圈闭、沉积、储层的特点及油气聚集规律.下第三系深层圈闭类型多、勘探领域广、储集层存在异常孔隙和次生孔隙发育带;海相碳酸盐岩可以生油得到证实,有的地区可以形成好的储集层;用低成熟油理论作指导寻找浅层油气资源等.丰富的油气资源和较好的石油地质条件,使渤海湾盆地继续加强勘探有良好的前景.
