地壳抬升作为一种重要的地质现象可使油气藏上升至地表并遭到破坏。如果地壳抬升不足以使油气藏上升至地表,那么它也会对油气藏的保存产生重要影响。地壳抬升可使油气藏盖层毛细管封闭能力增强,压力和烃浓度封闭能力减弱;地壳抬升使断层垂向封闭性减弱,甚至开启;地壳抬升可以使地表水、游离氧和细菌直接作用于油气藏,使之遭到水洗、氧化和菌解破坏作用;地壳抬升可使气藏的天然气扩散损失量进一步增大,不利于气藏保存。

Crust uplift, as an important geological phenomenon, can make oil or gas pools reach earth’s surface and destroy. If crust uplift can’t make oil or gas pools reach earth’s surface,it will give an important influence to preservation of oil or gas pools. Crust uplift can increase the capillary sealing ability of caprock and decrease the pressure and hydrocarbon concentration of caprock. Crust uplift can decrease the sealing ability of faults and make them open. Crust can make water from earth’s surface, oxygen in free phase and bacterium contact with oil or gas pool,make oil or gas pools take place water washing,oxidation and bacterial degradation.Crust uploft can make gas dffusiong lose amount from gas pool increase,can't be favorable for oil or gas to preserve.
