准噶尔盆地东部在石炭系褶皱基底上经历了三个发展阶段即:二叠纪前陆型陆相盆地演化阶段、三叠纪-白垩纪震荡型陆相盆地演化阶段和第三纪前陆型陆相盆地演化阶段。震荡型陆相盆地演化时期是盆地东部地区油气运移成藏的重要时期,形成了多套储盖组合,二叠系是主要的烃源层,二叠系和侏罗系是主要的储集层。在此基础上探讨了油气成藏模式,提出了应选择白家海凸起上的石炭系-三叠系、阜康断裂带,阜东斜坡区-白家海凸起侏罗系和沙帐-北三台凸起作为研究区今后的油气勘探目标的建议。
The eastern part of the Junggar Basin has experienced three stages of development on the Carboniferous fold base: the Permian foreland continental basin evolution, the Triassic-Cretaceous turbulent continental basin evolution and the Tertiary foreland Continental basin evolution stage. The evolutionary period of the oscillatory continental basin is an important period of hydrocarbon migration and accumulation in the eastern part of the basin, forming multiple sets of reservoir-cap assemblages. The Permian is the major hydrocarbon source. Permian and Jurassic are the major reservoirs Floor. On this basis, we discussed the hydrocarbon accumulation model, and proposed that the Carboniferous-Triassic, Fukang fault zone, the Fu Dong slope-Baijian Sea uplift Jurassic, As a research area for future oil and gas exploration goals of the proposal.
