| 摘 要： | 柴达木盆地中、新生代沉积构造演化经历了5个阶段:早、中侏罗世伸展断陷阶段,晚侏罗世—白垩纪挤压反转阶段,古近纪弱断陷阶段,新近纪的中新世—上新世早期坳陷阶段和上新世晚期—全新世挤压反转阶段。沉积构造演化控制盆地烃源岩的展布,盆地演化过程中的两次挤压反转期是圈闭构造的主要形成期,控制盆地油气分布。

| Abstract: | Qaidam Basin has undergone five stages in sedimentary structural evolution during Mesozoic-Cenozoic including the Early-Middle Jurassic extensional fault depression,Late Jurassic-Cretaceous compressive reversal,Paleogene weak fault depression,Miocene to early Pliocene sag,and late Pliocene-Holocene compressive reversal.The evolution controlled the distributions of the hydrocarbon source rocks.The two compressive reversal stages of the basin evolution are main stages for forming of the trap structures,which controlled the hydrocarbon occurrence in the basin. |
