摘　　要：在岩心和测井资料分析的基础上,通过对高尚堡油田高5断块沙三段的岩石学特征、粒度分布、沉积构造、泥岩颜色以及生物化石等方面研究,明确高尚堡油田高5断块沙三段为一套近源陡坡扇三角洲沉积体系,发育有扇三角洲前缘亚相,沉积微相主要为水下分流河道、河口坝、席状砂、水下分流河道间。Based on the analysis of core and logging data,this paper studies the petrological characteristics,grain size distribution,sedimentary structure,mudstone color and biological fossils of Sha 3 member in Gao5 fault block of Gaoshangpu Oilfield.It is clear that Sha 3 member in Gao5 fault block of Gaoshangpu Oilfield is a set of near source steep slope fan delta depositional system,with fan delta front subfacies developed,and the sedimentary microfacies are mainly underwater distributary channel,estuary dam,sheet sand and subaqueous distributary channel.
