摘要(Abstract)：

渤海湾盆地勘探已进入高成熟阶段,必须加大新领域勘探,才能获得新发现。渤海湾盆地的新近系超覆在古近系及前古近系不同时代地层和不同构造单元之上,是分布最广的层系,分析认为新近系的构造具有明显的继承性,构造大、幅度小、埋藏浅;油藏的成藏期较晚,为次生性油藏,储层物性较好,具备良好的成藏条件,油藏的主控因素为断层、圈闭、披覆背斜;辽河、大港和冀东油田的滩海地区的浅层新近系有利构造带是优先勘探方向。
The exploration of Bohai Bay Basin has entered into high-maturity stage,so the exploration in the new region must be focused to find out new recovery.Neogene overlaps are located on the different formations and structural units of the previous Neogene and the most widely distributed.The analyses show that the structures are characterized by obvious inheritance,and moreover are featured by larger structural area,smaller amplitude and shallow buried depth;the accumulation and enrichment period of the oil reservoirs is rather later,so the associated property of the reservoirs is very obvious,the physical properties are pretty better and then much better accumulation conditions are possessed.Thus the shallow Neogene system in the offshore areas of Liaohe Oilfield,Dagang Oilfield and Yidong Oilfield are favorable structural belts for further optimized exploration orientations.
