摘要: 根据岩性、沉积构造、古生物化石和地球化学标志, 系统分析了艾维尔沟地区上二叠统芦草沟组的沉积环境。本区深湖相沉积十分发育,并在此背景上沉积了近岸浊积扇和典型的浊积岩。其中深湖相暗色泥、页岩和油页岩构成了良好的烃源岩,其上覆的中-上三叠统小泉沟群为有利的储集层,表明吐哈盆地南部坳陷的侏罗系以下具有良好的油气勘探前景。

Abstract: On the basis of lithology, sedimentary structure, fossils and geochemical markers, this paper systematically analyzed the sedimentary environment of Upper Permian Lucaogou formation in Aiweiergou area.Near-shore turbidite fan and typical turbidite rock are deposited on well-developed deep-lake facies sediments in this area.The deep-lake facies dark mudstone, shale and oil shale are better source rock, and the overlying Mid-Upper Triassic Xiaoquangou group is the favourable reservoir.All these support that there is higher hydrocarbon potential below Jurassic in the depression of southern Turpan-Hami basin.
