摘要
莱州湾至辽东湾的海域内,新生代断裂发育,具两个北东向雁行排列的断裂带,即营潍断裂的东支和西支。断裂长期活动,以其强裂的活动期,间以微弱活动期。构造运动方向向左行转变为右行,具明显的幕式演化特征。不同活动期发育了不同的生储盖组合,其有利相带的分布、复杂的油气聚集、油气田的形成等与断层活动密切相关。
The Cenozoic faults developed in the sea area from Laizhou Bay to Liaodong Bay.There are two fault- ed zones which orientation are northeast-southwest and represent as an echelon arrangement,i,e.the east branch and west branch of Yingwei fault zone.The faults are active long time,and the strong active periods are interrupted by the weak active periods.The direction of the structure movement is changed from sinistral faults to right lateral faults and they represent distinct episodic evolution characteristics.There are different plays developed in the different active periods.The distribution of favourable facies,the complex accumula- tion of oil and gas and the form of oil and gas fields are closely relative to the activation of faults.
