塔里木盆地断裂带集中发育了60%以上的油气圈闭,其形成大多与断裂关系密切。不同系统的断裂控制了油气圈闭样式类型,逆冲滑脱作用主要形成堆叠叠瓦、断弯、断展和断滑褶皱,背冲作用主要形成背冲断块、背冲背斜和牵引圈闭,走滑作用主要形成花状和雁列褶皱。它们已成为盆地油气勘探的重要目标。

Above 60% oil/gas traps whose formation mainly has close relationship to faulting are developed concentratedly within the fault zone of the Tarim Basin.Faulting of different systems controls the types of oil/gas traps.Thrust decollement mainly results in stacking imbricate,fault bending,fault spreading and fault sliding folds,back thrusting in back thrusting blocks,back thrusting anticlines and tractive traps,and strike slip displacement in efflorescent and en echelon folds.They have become the important targets for the oil/gas exploration of the basin.
