| 摘 要： | 在对鄂尔多斯分轩东南部构造、沉积演化及地层特征认识的基础上，分析了该地区油气成藏的主要地质条件，认为三叠系延长组三角洲砂体是该地区油气聚集的主要场所，局部也可能发育延安组河道砂岩油气藏，由差异压实作用形成的低幅度鼻褶构造是油气富集成藏的关键因素，延长组上覆地层遭受剥蚀的程度决定了油气藏保存条件的好坏。

| Abstract: | Based on the structure, sedimentary evolution and stratigraphic feature; this paper analyzes the major geologic conditions of hydrocarbon reservoir-forming in South-East Eerduosi Basin,proposes that Triassic Yanchang Formation delta sandstone should be of the main hydrocarbon accumulation in this area,with locally Jurassic Yanan Formation channel sandstone reservoir. The tiny structural nose formed by differential compaction is the key factor for hydrocarbon to concentrate. Stratigraphic denudation controls the preservation condition of hydrocarbon. Meanwhile, the paper outlines the oil and gas distribution and the exploration direction in near future. |
