| 摘 要： | 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。

| Abstract: | According to the analysis of seismic and well log sequence stratigraphy, four sequences are identified in Upper Paleozoic of north Ordos Basin, which are all separated by the regional erosion surfaces and channel washing surfaces. The characteristics of sequences reflect the process of evolution of the Ordos Basin which experimented the formation, development, waning and consumption of epicontinental basin. The offshore sandstone of Carboniferous and channel sandstone and alluvial fan of Permian are mainly reservoir rocks. In sequence stratigraphic system, vertical development of the reservoir is controlled by base level cycle changes, and spatial distribution is restricted by the palaeogeomorphology. The distribution of advantageous reservoir is predicted on the basis of the comprehensive analysis of seismic profiles and well logs. |
