摘　　要：以鄂尔多斯盆地靖边气田南部陕200井区马家沟组马五1-4地层为研究对象，研究高分辨率层序地层对沉积微相和储层发育状况的控制作用。研究表明：马五1-4亚段构成一个长期基准面下降半旋回，可划分为4个中期基准面旋回和16～19个短期基准面旋回，长期基准面旋回对马五1-4亚段的沉积微相和储层的控制作用是概略性的，通过高分辨率层序地层对比技术得出中期基准面旋回和短期基准面旋回对沉积微相和储层垂向上分布的控制是显著的。This paper deals with control of high resolution sequence stratigraphy over the development of sedimentary microfacies and reservoirs in the Fifth Member of the Majiagou Formation in Shan200 well block of the Jingbian gas field in Ordos basin. The 1-4 Submembers of the Fifth Member constitutes an asymmetric long-term base level cycle which can be divided into 4 middle-term base level cycles and 16 to 19 short-term base level cycles. The study shows that control of the middle-term and short-term base level cycles over sedimentary microfacies and reservoirs dominates over that of long-term base level cycle.
