通过地震和测井层序地层分析，可在鄂尔多斯盆地北部上古生界识别出４个地震层序，层序界面均以区域性侵蚀面或河道冲刷面为边界。层序的发育特征反映了鄂尔多斯盆地在晚古生代经历了陆表海盆地的形成、发展、衰退和逐渐消亡的过程。储集层主要是石炭系的滨岸砂体、二叠系的河道砂体以及冲积扇砂体。在层序地层体制中，储层的纵向发育受基准面升降变化旋回的控制，而平面展布受古地貌的制约。通过地震与钻井的综合分析，具体预测出有利的储集砂体分布。
Through seismic and logging sequence stratigraphy analysis, four seismic sequences can be identified in the Upper Paleozoic in the northern Ordos Basin. The boundaries of the sequence boundaries are either the regional erosion surface or the river erosion surface. The developmental characteristics of the Ordos Basin reflect that the Ordos Basin experienced the formation, development, decline and gradual disappearance of the continental shelf in the Late Paleozoic. The reservoirs are mainly the Carboniferous coastal sand bodies, Permian channel sand bodies and alluvial fan sand bodies. In the sequence stratigraphic system, the vertical development of the reservoir is controlled by the gyration of the base level, while the plane distribution is controlled by the paleogeomorphology. Through the comprehensive analysis of earthquakes and drilling, we can predict the favorable distribution of reservoir sand bodies.
