| 摘 要： | 鄂尔多斯盆地的苏里格地区上古生界二叠系山1段至盒8上段主要为一种复杂的辫状河沉积体系。以层序地层对比结果为基础，在全区范围内统计每一个准层序中砂体钻遇率，并绘制砂体钻遇率变化曲线；统计各准层序中1m以上的砂体厚度，用两种方法计算每一准层序中砂体的平均厚度，绘制砂体平均厚度的变化曲线。从层序地层学的角度对钻遇率变化曲线和砂体平均厚度变化曲线进行解释，揭示砂体展布与基准面变化的关系，从而建立河道砂体的横向展布模型，初步预测有利储层。 |

| Abstract: | The formations from the 1st member of Shanxi formation to the upper 8th member of Xiashihezi in Permian, Neopaleozoic are mainly sedimentary system of complex braided stream in Sulige area of Eerduosi Basin. According to the result of sequence stratigraphic correlation, drilling ratio and thickness of sandbody whose thickness is over 1m in every subsequence of the whole area are figured out,average thickness is calculated by two methods, and variation curves of the drilling ratio and the average thickness of sandbodies are made. Those curves are explained by sequence stratigraphy, and the relationship between the change of base level and sandbody spreading is discovered. At last, lateral spread model of channel sandbody is built for forecasting the favorable reservoir primarily. |
| Keywords: | braided river drilling ratio of sandbody average thickness of sandbody base level Sulige |
