摘　　要：为了掌握高家沟长2油层的储层分布规律,促进油气勘探取得新进展,在岩心观察、测井资料及前人研究成果的基础上,通过对大量物性资料、测井资料统计分析,确定了高家沟长2油层的沉积类型为辫状河流相沉积的河道亚相,识别出了河底滞留沉积、心滩、河道填积、决口扇、泛滥盆地等5种微相类型。In order to master the reservoir distribution in Gaojiagou reservoir of Chang 2,and promote oil and gas exploration have made new progress.On the basis of the observation of cores,well logging data and forefathers’ research results.Based on statistical analysis of physical property data and logging data,the sedimentary types of Gaojiagou Chang 2 is determined for braided fluvial facies sedimentary facies of the channel.There are five kinds of microfacies types are identified,channel lag, diara, channel filling,crevasse splay,flood basin.
