摘　　要：鄂尔多斯盆地上古生界含气系统是自生、自储、自盖的煤成气含气系统，上古生界煤层为其最主要的烃源岩，应用高分辨率层序地层学理论分析盆地煤层的各种成因类型，指出各自对应的层序位置及对比特征，以期对煤层的层序地层特征有一个统一的认识。The Upper Paleozoic in Ordos basin is a gas system of self generating,self reservoiring and self sealing,in which coal bearing formations are the most principal source rock.Using the concepts of high reso lution sequence stratigraphy,this paper analyses origins,sequence levels and correlations of various coal bearing formations,in order to get a comprehensive understanding of coal bearing sequence stratigraphy in the basin.
