摘　　要：通过对十屋油田营五段岩心的详细观察与描述,结合测井曲线、单井沉积相分析、联井剖面分析和平面相分析研究,表明研究区岩性粗,块状层理、滑塌变形构造发育,粒度概率曲线多呈弧形和一段式,属典型的扇三角洲沉积特征。研究区划分出2种沉积相、5种亚相、13种微相类型,其中扇三角洲水下分流河道微相最发育。联井剖面和平面特征表明,营五段下部主要发育水下分流河道微相,上部发育席状砂、河口坝微相和湖泊相。平面上其北部和东南部发育水下分流河道微相,西部发育半深湖-深湖相。Through the detailed observation and description of cores in Ying 5 member of shiwu oilfield,combined with the analysis of well logging curves,single well sedimentary facies,joint profile and the plane profile of this area,the study show that the area has coarse lithology,massive bedding and slump deformed structure.The grain size probability curves are mainly arcuate and one-segment,belonging to typical fan delta characteristics.This area can be divided into 2sedimentary facies,5subfacies and 13 microfacies.And submerge distributary channels are the best developed microfacies.Joint and plane profile characteristics show that the lower ying 5member is mainly developed submerge distributary channels microfacies and the upper ying 5member is mainly developed sand sheet,estuary bar microfacies and lacustrine facies.On the plane,northern and eastern-southern parts developed submerge distributary channels microfacies,and western developed semi-deep facies and deep lacustrine facies.
