摘　　要：新北油田北部凹陷众多,成藏条件比较复杂,尤其是馆陶组上段。通过对岩心录井、测井曲线特征等分析,结合前人研究,对新北油田北部馆陶组上段沉积地层进行了重新划分,将前3个砂层组划分为12个小层,研究其地层发育特征。并以单井沉积相分析为基础,对新北油田北部馆陶组上段沉积相进行重新分析,认为该段为三角洲平原亚相,物源来自北东方向,主要发育分流河道、分流间湾、天然堤、决口扇等微相。在馆陶组上段沉积时期,沉积环境整体较稳定,沉积相展布变化不大,仅第二砂层组沉积时期,水体相对较动荡,砂体量、分流河道走向多变。The stratigraphic redivision and sedimentary facies analysis are made for the upper member of the Guantao Formation in northern Xinbei Oil Field, Shandong according to the core logging and well logs in combination with the previous data. The first three sand sets are redivided into 12 layers. The upper member of the Guantao Formation is composed of the delta plain subfaeies which may be subdivided into distributary channel, interdistributary bay and natural levee microfacies, occasionally with crevasse splay microfacies, and the distribution patterns of the sedimentary facies were less variable. During the deposition of the upper member of the Guantao Formation, the sedimentary environments were relatively stable, and the sediments mainly derived from the northeastern part of the basin.
