摘要
在鄂尔多斯地区，除陕北大气田外，其它地区的勘探前景如何是大家所关心的问题。为此，从该区下古生界沉积特征入手，研究了成藏条件，评价了勘探有利区。研究认为，鄂尔多斯地区存在着中央、富县─黄陵、吕梁和乌兰格尔等四个古隆起，它们控制了该区奥陶系的沉积，产生了不同的岩性分区。综合分析后评选出４个有利勘探区：①庆阳古隆起东斜坡；②乌兰格尔古隆起南斜坡；③盆地南部富县─黄陵古隆起南斜坡；④盆地西部中奥陶统海底扇分布区。
How is the exploration potential of the districts in Eerduosi Basin is a problem considered by people except the Large gas field in North Shanxi. Aimed at the problem and started from the deposition feature of Lower Palaeozoic erathem, the reservoir-forming conditions are studied and the favourable districts for exploration are evaluated. It is deem by studying that there are 4 palaeohighs i. e. Zhongyang, Fuxian-Huangling,Luliang and Wulangeer in Eerduosi area. The Ordovician deposition in the area is controlled by them and the districts with various lithology are produced. 1 favourable exploration districts are sorted out after comprehensively analysing. They are Qingyang palaeohigh east slope. Wulangeer pelaeohigh south slope, Fuxian-Huangling palaoohigh south slope in the south part of the Basin and the submarine fan distributive district of Middel Ordovician Series in the west part of the Basin.
