摘要
走滑构造体系盆山耦合常由于走滑断层弯曲所产生 ,结合油气勘探中盆地—区带—圈闭 3个层次 ,相应地划分为 3类走滑断层 :(1)转换断层为控盆断层 ;(2 )转移断层为控带断层 ;(3)撕裂断层为控藏断层。走滑断层伴生盆地按力学性质可以划分为 :(1)走滑伸展盆地 ;(2 )走滑挤压盆地及 (3)走滑旋转盆地。转移断层可以与裂谷盆地或前陆盆地复合 ,发育断裂互联网络 ,形成雁列褶皱或雁列断块油气区带 ;撕裂断层与低角度正断层或逆冲断层相交时常形成有利圈闭 ,如活板构造等。
The bending of the strike slip fault dominated the forming of basin and mountain along the fault. This is so-called strike slip system basin-mountain coupling. The strike slip fault can be divided into three different levels corresponding to the different scales of petroleum exploration targets, such as transform fault dominated the basin forming, transfer fault controlled the play, and tear fault charged the trap. According to the mechanical scenario, the strike slip dominated basins can be divided into three types: (1) transtensional basin; (2) transpressional basin; and (3) transrotational basin. The compound of transfer fault with rift basin or foreland basin can form the linked fault family, which produced the echelon fold or echelon fault block. The echelon fold and echelon fault block controlled the plays. The tear fault intersected with low angle normal fault or thrust fault can form some traps, e.g. trap-door structure trap.
