摘　　要：通过对马岭油田延十段小层沉积相类型的分析认为马岭油田在延十中晚期已由前期的限制性沟谷充填式的河流沉积体系,发展到具有游荡性特点的辫状河沉积,至延十末期还发育了辫状河三角洲沉积。Through analyzing the type of Y10 sublayer sedimentary facies in Maling Oilfield is developed into braided stream sediment with wandering nature from previous filled fluvial sedimentary system of confined trenches in the mid-late Y10, and to braided stream delta of late Y10.
