Abstract

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
