摘要
南堡凹陷第三系依成因层序界面及区域构造活动 ,可划分出 7个超层序 ,与渤海湾其他盆地相比 ,仅缺失第 2超层序。每一超层序一般是一个完整的生、储组合 ,中部层序组的深湖泥岩为好 -较好的生油岩 ,下部层序组的楔状粗粒沉积体系是良好的储层。
According to the genetic sequence interfaces and regional tectonic movement,Tertiary strata in Nanpu depression can be divided into 7 super-sequences,missing only the 2nd super-sequence by comparison with other basins in Bohai Gulf. Each of these super-sequences generally constitutes a complete source-reservoir assemblage.The deep lacustrine mudstone in the middle sequence set is a relatively good source rock, and the wedge-shaped, coarse-grain sedimentary system in the lower sequence set is a good reservoir rock. So, the most prospective position for deep hydrocarbon reservoir exploration might be the part of coarse-grain deposition system in the lower position ,which is extending to the central part of the basin.
