摘 要: | 塔东地区的大地构造演化经历了前震旦纪基底形成阶段、早加里东期大陆边缘断陷盆地阶段、晚加里东期隆后坳陷阶段、海西期前陆隆起阶段、印支期—早燕山期冲断前陆盆地阶段、晚燕山期陆内坳陷盆地阶段和喜山期断陷盆地阶段;大地构造演化的不同阶段不仅形成了多套烃源岩,而且控制了古生界和中新生界两套不同的油气成藏系统。古生代油气成藏系统主要在塔东低凸起和古城鼻隆地区,中生代油气成藏系统在英吉苏凹陷—孔雀河斜坡一带地区。

GEOTECTONIC EVOLUTION AND PETROLEUM ACCUMULATION IN EAST TARIM |
| |
Abstract: | The geotectonic evolution in east Tarim basin has involved seven stages:basement formation in the pre-Sinian,faulted blocking of continental margin in pre-Caledoni an epoch,sag stage in late-Caledoni an epoch,foreland upwarp from Hercyni an to Indo-Chinese epoch,foreland b asin from Indo-Chinese to pre-Ye nshan epoch,intracontinental sag b asin in late-Yenshan epoch and faulted basin in Himalayan epoch.Di-fferent hydrocarbon-bearing rocks were formed in different stages of geotectonic evolution,and two different Mesozoic-Cenozoic oil-gas reservoir-forming systems are controlled b y geotectonic evolution.The Palaeozoic oil and gas accumulation has been fou nd in east Tarim salient and Gucheng n ose area.The Mesozoic-Cenozoic systems have been found in Yinjisu sa g and Kongque river slope. |
