摘要:

塔里木盆地演化受控于板块构造旋回的发展:(1)离散期,塔里木板块从超大陆裂解,塔东地区形成南华纪一震旦纪裂谷盆地;(2)漂移期,塔里木板块漂移一热沉降,形成古生代克拉通盆地及台地型油气系统,发育古隆起和坡折带油气区带;(3)聚合期,塔里木板块及周缘形成盘一山转换,但在塔东地区缺失二叠系一三叠系层序;(4)大陆旋回期,塔里木盆地在侏罗纪时呈现为造山后伸展,形成裂陷盆地,新生代开始陆内造山.形成盆一山耦台,塔东属走滑一前陆盆地,形成造山型油气系统,发育逆冲一褶皱型及走滑一褶皱型油气区带。

Abstract:

The evolution of the Tarim Basin waS dominated by the plate tectonic cycling:(1)divergent cycle phase:Tarim plate was separated from super-continent,and the rift basin was formed in the eastern part of the Tarim Basjn in Nanhua-Sinian time;(2)drifting cycle phase:Tarim plate was experienced the drifting and thermal subsidence. The Paleozoic craton and its related petroleum pIays were formed there,such as the paleo-uplift play and continental shelf break play;(3) convergent cycle phase:Tarim plate and its surrounding areas were converted from basin to mountain.The hiatus of Permian-Triassic sequences was in the eastern part of the Tarim Basin;(4)continental cycle phase:The rift basin was formed since preliminary of the post-orogeny extension phase in Jurassic time.The intra-continent orogeny started since Cenozoic
time,the basin-mountain coupling system was developed there. The strike-slip foreland basin was formed in the eastern part of the Tarim Basin,and its related orogenic type petroleum system was formed.The thrust fold and strike-slip fold type play were formed.

Key words: platform type petroleum system, orogenic type petroleum sysIem, paleo-uplift, continental shelf break, thrust-fold, strike-slip fold
