摘　　要：针对商河油田沙二下亚段储层砂体厚度小且与泥岩薄互层的特点,通过对商河油田沙二下亚段沉积相横向展布及垂向分布规律的研究,结合同沉积断层的发育情况,系统分析沙二下亚段沉积体系发育的构造动力机制。由自北向南呈阶梯状分布的多级构造调节带和多级坡折带联合控制了商河砂体的沉积相带展布和古水系的方向,且控制着沉积微相的展布。In view of the characteristics of the thin and interbedded reservoir sandstone and the mudstone layers, this article studied the lateral and vertical distributions of sedimentary micro-facies of the lower Es2 in Shanghe Oilfield, and systematically analyzed the tectonic mechanism of sedimentary system of the lower Es2 in line with the development of sedimentary faults. It was considered that the multi-ordered tectonic belts and the multi-level slope belt control the distribution of the sedimentary facies and the flowing path of the ancient river system, characterized by descending from north to south with a step shape. The study provided effective evidence for the future exploration.
