| 摘 要： | 南堡凹陷柳南地区濒临海域,断层发育,构造与沉积都十分复杂。通过对该地区的沉积体系特征和物源体系的深入讨论,精细刻画了研究区沉积体系的平面展布规律和垂向演化特征,进而划分了该区的有利储集相带。南堡凹陷柳南地区在东营组沉积时期主要发育扇三角洲、近岸水下扇、滑塌浊积扇和湖泊相沉积体系;垂向上构成了一个完整的湖盆扩张-萎缩的充填序列,Ed3沉积时期为一个湖面萎缩-扩张的短期旋回;认为在该地区,Ed1和Ed3沉积时期发育较有利的储层,Ed2沉积时期生烃潜力较大。 |
| 关 键 词： | 南堡凹陷 柳南地区 东营组 沉积体系 |

| Abstract: | Sag Liunan region in Nanpu endangered sea, fault activity strong, has very complex tectonic and sedimentary distribution. By the further discussion of sedimentary features and provenance system on this area, the authors fine depicted the flat distribution rules and vertical evolution characters, then divided the favorable reservoir facies. This area mainly developed fan-delta deposition, nearshore subaqueous fan, slump turbidity fan and lacustrine facies sedimentary system. It is constituted by a complete expansion -contraction cycle at the lake level vertical in Dongying Formation and a short cycle from contraction to expansion in Ed_3 segment. In this area, Ed_1 and Ed_3 segments develope favorable reservoirs, and Ed_2 segment has hydrocarbon potential. |
| Keywords: | Nanpu sag Liunan region Dongying Formation sedimentary system |
