| 摘 要： | 从区域沉积背景出发，以岩心和测井资料分析为基础，对松辽盆地扶余油田泉四段的岩石类型、粒度分布、沉积构造、泥岩颜色及地球化学特征等各类沉积相标志进行分析，确定其为三角洲沉积，包含三角洲平原和前缘亚相。其中，平原亚相可识别出分支河道、决口扇、天然堤、废弃河道、湖泊沼泽微相；前缘亚相可细分为水下分支河道、河口坝、远沙坝、水下天然堤和支流间湾等微相。依据沉积微相与地层格架的成因关系，在中期基准面旋回的控制下应用取心关键井建立了沉积微相的定量识别图板，对非取心井进行沉积微相的定量识别与划分，并在此基础上绘制了沉积微相的平面及剖面图，总结了微相类型的平面和纵向展布规律及其与含油性的关系，指出分支河道砂体发育规模、连续性、储集性、含油性最好，其次为河口坝砂体，为研究区下一步的开发方案提供地质依据。

| Abstract: | Based on the regional sedimentary background and the core and logging data,and from an analysis of its facies markers,such as rock type,granularity distribution,sedimentary structure,mudstone's colors and geochemical features,Q4 Member in Fuyu Oilfield,Songliao Basin is identified as in a deltaic deposition which includes delta plain and delta front.The delta plan is composed of branch channel,crevasse splay,natural levee,abandoned channel,and so on.The delta front is composed of underwater distributary cha... |
