摘要：

郯庐走滑断裂带经历了多期活动,影响和控制走滑断裂带内的油气成藏.金县地区处于走滑断裂带内,并且位于富生烃凹陷——辽中凹陷的北段,广泛发育来自其东侧的胶辽隆起区的三角洲、扇三角洲砂体,成藏条件优越,是近年来渤海海域的重大发现之一.伴随着走滑断层的活动,断层较发育,可将其划分为3组不同走向的断层组合,其中NNE向走滑断层和近EW向走滑调节断层分别是金县地区东盘及西盘的主要油气运移通道,控制古近系油气的运移层位及赋存深度.

关键词: 古近系, 油气运移, 郯庐走滑断裂带, 金县地区

Abstract:

Tanlu strike-slip fault zone had experienced several phases of movement,exerting strong influence and control upon the hydrocarbon pooling within the zone.Located inside the strike-slip fault zone and also the north part of a hydrocarbon kitchen(Liaozhong depression),Jinxian area,one of the major discoveries in Bohai offshore in recent years,possesses favorable hydrocarbon pooling conditions with its extensive well-developed delta and fan delta sandbodies sourced from Jiaoliao,a uplift to its east side.Faults are relatively well developed along the zone and can be divided into 3 different fault sets according to their strikes,among which the NNE-trending strike-slip fault and near NE-trending strike-slip accommodation fault are the main hydrocarbon migration pathways for the east and west fault walls in Jinxian area,and control the migration horizons and pooling depth of the Paleogene hydrocarbon.

Key words: Paleogene, hydrocarbon migration, Tanlu strike-slip fault zone, Jinxian area
