摘　　要：鄂尔多斯盆地发育典型的岩性油气藏。层序地层学理论是指导岩性油气藏勘探开发强有力的工具之一，系统研究盆地的层序地层具有非常重要的现实意义；考察鄂尔多斯盆地上古生界层序地层学的研究历史，认为各研究者是依据不同理论体系、应用不同研究方法、在不同层序级别开展的，取得的是既相互联系又有区别的结果，至今仍然未形成统一的层序级别划分方案；在系统分析和总结前人研究成果的基础上，依据现代的层序地层学理论，制定出鄂尔多斯盆地上古生界层序的划分方案：上古生界划分为1个一级层序、4个二级层序、22个三级层序；最后，指出了盆地层序地层学的研究方向。Typical lithologic reservoirs have been developed in Ordos basin. The sequence stratigraphic theory is one of the powerful tools to guide the exploration and development of lithologic reservoirs. Systematic research of sequence stratigraphy of the basin has great realistic importance. Proceeding from the history of sequence stratigraphy research in Ordos basin, we could find that the results have not only some relationship with each other but also some differences between them, and have not formed a unified scheme of sequence level division so far, due to application of various research methods and different theoretical systems by different researchers. According to the present day theory of sequence stratigraphy, and on the basis of systematic analyzing and summing up the predecessors＂ fruits of research, a program of classifying the Upper Paleozoic stratigraphic sequences of Ordos basin is worked out, that is, the Upper Paleozoic is divided into one Class-Ⅰ sequence, four Class- Ⅱ sequences and 22 Class-Ⅲ sequences. Finally, the direction of sequence stratigraphy research is put forward.
