摘要: 柴达木盆地西部地区的逆断层可分为同生逆断裂、后生-同生逆断裂和后生逆断裂三种基本类型。同生断层的长期活动对沉积有着明显的控制作用,形成了良好的储集层和盖层。该地区逆断裂的发育主要经历了同生、后生、同生3个阶段,由于同生断层的发育比较早,活动时间比较长,使油气长期处于运移、聚集和富集的状态,不但为油气的纵向运移起到通道作用,也为储集层和生油层提供了通过断层面进行横向接触的机会。

Abstract: The reverse fault in western Qaidam basin can be divided into three radical types as contemporaneous reverse fault, epigenetic-con-temporaneous reverse fault and contemporaneous fault. The long-term activity of contemporaneous controls the deposits apparenly,forming good reservoir and caprock. The development of these reverse faults underwent the contemporaneous, epigenetic and contemporaneous stages. The earlier development and long-term activities of contemporaneous reverse faults allow petroleum in this area to be in long-term migration, ac-cumulation and enrichment, not only as vertical passages for migration, but also as lateral connection channels between the reservoir and the source rock.

Key words: Qaidam basin, reverse fault, contemporaneous fault, petroleum migration, petroleum accumulation
