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。粗粒型低位体系域向盆地中部延续的部分是深部油气藏勘探的最有利的部位。

Abstract:

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.

Key words: sequence interface, Tertiary, hydrocarbon reservoir, oil source rock, reservoir, Nanpu depression
