| 摘 要： | 高柳地区古近系地层经历了从盆地初始裂陷、强烈裂陷到裂陷衰退一系列过程,形成了同沉积断裂坡折带—同沉积构造弯折带—无坡折的缓坡地貌型层序的地层演化系列,因而该地区古近系存在同沉积构造断裂坡折带、同沉积构造弯折带和无坡折的缓坡地貌3种坡折带类型,它们控制了扇三角洲、水下扇、浊积扇和下切水道充填砂体的分布.同沉积断裂坡折带和同沉积构造弯折带之下的低位域砂体是该区隐蔽油气藏勘探的主要目标. |
| 关 键 词： | 南堡凹陷 坡折带 低位域砂体 隐蔽圈闭 |

| Abstract: | The Eogene in Gaoliu area of Nanpu Sag undergoes the process of initial rifting-intensive rifting-decline rifting,and therefore,the stratigraphic evolution sequence of syndepositional faulted slope-break sequence-syndepositional structural slope-break sequence-gentle slope-break sequence is formed.So in the Eogene,there are three types of slope-break zones:syndepositional faulted slope-break zone,syndepositional structural slope-break zone and gentle slope-break zone.These slope-break zones control the distribution of fan delta,underwater fan,turbidity fan and incised water channel sandstones.The lowstand sandbodies under the syndepositional faulted slope-break zone and the syndepositional structural slope-break zone are the main subtle traps as exploration targets in the area. |
| Keywords: | Nanpu Sag slope-break zone lowstand sandbody subtle trap |
