| 摘 要： | 松辽盆地肇源南地区，在构造上位于松辽盆地的中央坳陷区和东南隆起区两个一级构造单元的交接部位。在了解区域沉积背景的情况下，以岩心观察获得的岩石类型、岩相类型与相组合特征，结合测井相分析，可以在扶Ⅱ油层识别出4种沉积相类型，即曲流河道、决口河道、决口扇和冲积平原相。以此为基础，根据岩心微相分析、小层砂体形态和测井剖面对比及井间横向对比，编制了不同层位的沉积微相平面展布图，揭示了各沉积微相的时空展布和变化规律，为下一步的油田开发奠定了基础。 |

| Abstract： | The study area is situated in the south of Zhaoyuan Area of the Songliao Basin. In structure, it is located in the contact place between the middle downwarping region and southeast uplifted area which are the two first order tectonic unit in Songliao Basin. On the basis of realizing the sedimentary system and tectonics, there are four types of sedimentary facies in the Fu Ⅱ oil-bearing layer located in the south of Zhaoyuan Area of Songliao Basin, including meander channels, crevasse channels, crevasse fans, alluvial plains and shallow lakes, with the methods of analyzing the log facies and observing cores to acquire the types of the rocks, the types of lithofacies, and the features of facies association. Based on these, according to the core microfacies analysis, the shape of sand body and the comparison between the logging profiles and the wells, the drawings of microfaceis in different formations are mapped to illustrate the evolvement and change of different microfacies. This study is important for oil field development. |
