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熏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个阶段熏由于同生断层的发育比较早熏活动时间比较长熏使油气长期处于运移、聚集和富集的状态熏不但为油气的纵向运移起到通道作用熏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。
The reverse fault in western Qaidam basin can be divided into three radical types as contemporaneous reverse fault, epigenetic-contemporaneous reverse fault and contemporaneous fault. The long-term activity of contemporaneous controls the deposits apparently, 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, accumulation and enrichment, not only as vertical passages for migration, but also as lateral connection channels between the reservoir and the source rock.
