| 摘 要： | 笔者在研究鄂尔多斯盆地晚古生代沉积体系的基础上，对晚古生代生烃源岩、储集层、盖层形成与展布进行了分析，提出了沉积体系对煤成气藏的控制作用；并认为盆地内部晚古生代煤成气藏是地层封闭的岩性气藏，储集体的分布主要受河流－三角洲沉积体系的控制，特别是山2期和盒9期的河流－三角洲沉积体系的控制，它们是盆内晚古生代煤成气藏的主力气层。

| Abstract: | The Late Palaeozoic humic gas pools in the Ordos Basin are believed to be the lithologic gas pools within the stratigraphic traps. The distribution of hydrocarbon reservoirs is generally governed by the fluvial and deltaic depositional systems, especially by those in the second member of the Shanxi Formation and the ninth member of the Lower Shihezi Formation. These fluvial and deltaic depositional systems have been identified as the principal gas beds in the Late Palaeozoic humic gas pools in the Ordos Basin. |
