| 摘 要： | 鄂尔多斯盆地北部的伊盟隆起区 ,特别是杭锦旗至东胜一带的地层发育大量的圈闭 ,它们是油气聚集成藏的场所。本文剖析了这些圈闭的类型和成因 ,指出它们是盆地北部天然气运移的有利指向区 ,是还原性气体的储存库和重要的扩散源 ;油气渗出和含氧含铀水渗入的交汇部位是铀成矿的有利场所。因此 ,查明圈闭和断裂构造 ,对分析油气运移方向及砂岩型铀矿预测具有实际意义

| Abstract: | In Yimeng upwelling area of the northern Ordos basin,especially its Hangjinqi-Dongsheng area,a lot of traps are developed.These traps are reservoirs of oil-gas.This paper analyses and discusses types and origins of traps,and suggests that the traps are favourable indication of natural gas in northern Ordos basin,and are the storage and important diffusion source of reducing gas,as well as favourable sites for the confluence of extrafiltrative oil-gas and ore -formation of uranium.Therefore,to ascertain the distribution of trap and fault structures is of practical significance in the analysis of oil-gas migration and the prognosis for uranium mineralization. |
