| 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. |
