摘　　要：针对油田开发中扶余油层砂体发育层薄、连续性差、变化复杂的情况,从野外露头的角度对松辽盆地东缘五色山和红星渔场泉头组沉积相类型、特征及变化规律进行分析。野外观察和实测结果表明,泉头组发育有冲积扇相、辫状河相、曲流河相3种沉积相及7种沉积亚相、12种沉积微相类型,经历了由冲击扇—辫状河—曲流河—辫状河—曲流河的沉积相演变过程。该研究为扶余油层深入开发提供了有益参考。Aimed at addressing the problems, such as the thin layer, poor continuity, and complicat- ed variation, as happens in Fuyu reservoir sand body during the oil field development, this paper, from the point of view of outcrop, analyzes the types, characteristics, and laws governing variation of sedimen- tary facies of Quantou formation occurring in Wuse Mountain and Hongxing Fishery in north of Songliao Basin. The observation and actual measurement of outcrop of Quantou formation shows that Quantou for- mation consists of 3 types of sedimentary facies, 7 types of sub-sedimentary facies and 12 types of micro- sedimentary facies, and experiences the sedimentary facies evolutionary process, such as alluvial fan, braided stream, meandering stream, braided stream, and meandering stream. The study provides the beneficial reference for the development of Fuyu oil layer .
