摘　　要：在岩心和录测井资料基础上,结合前期成果,对胜利油田孤南洼陷渤701井沙河街组沙三段上亚段展开沉积微相研究。该亚段发育曲流河相沉积,从中可识别出5种岩石相类型。分析认为该亚段可进一步划分出点砂坝、河漫滩、决口扇、河床滞留沉积,共4种沉积微相类型。The study of sedimentary microfacies of Bohai 701 wells in the third upper sub-member are based on core wells information,logging and mudlogdata,combinating with previous research results. The subfacies developed the meandering fluvial facies,and five types of lithofacies were identified. The microfacies of the studied area are divided into such four types： point bar,flood plain deposit,crevasse splay deposit and channel lag deposit.
