摘　　要：针对饶阳凹陷留西油田馆陶组上段沉积微相研究程度不够深入的问题,通过对岩心录井、测井曲线特征等分析,对留西油田东部馆陶组上段地层进行精细划分,将馆陶组一段和二段的4个砂层组划分为16个小层,研究其地层发育特征,并以单井沉积相分析为基础,结合测井相、平面相等分析,对研究区馆陶组上段沉积微相类型、展布特征及其演化规律进行了全面系统的研究。研究表明:研究区以曲流河和辫状河沉积为主,受基准面升降与沉积物供应等因素的影响,该区河流相砂体自下而上大致经历了曲流河发育期、辫状河-曲流河共存发育期、辫状河发育期3个阶段。In view of the problem that the study on sedimentary microfacies in the upper section of Guantao formation in the sunken Liuxi oil field, Raoyang, is not thorough enough, through the analysis on the characteristics of the core logging and logging curves, the upper layer of Guantao formation in the eastern Liuxi oil field was finely divided into 16 small layers to study the formation development characteristics, based on analysis on single-well sedimentary facies and combined with the analysis on logging phase and plane equality, a comprehensive and systematic study was carried out on the type of sedimentary microfacies, display features and evolution law in the upper section of Guantao formation in the research area.The study results show that the study area is mainly based on sedimentation of meandering streams and braided streams, and by the influence of the datum lift and sediment supply, the sand body of this river facies in this area has generally experienced the development period of meandering streams, the coexistence and development period of meandering streams and braided streams, and the development period of braided streams, from bottom to top.
