Taking Yan10 member of Bai211 well area of Nanliang oilfield as the research object, the stratigraphic subdivision, sedimentary facies type and sand body distribution characteristics are analyzed by making full use of drilling and core data. The results show that Yan10 formation can be subdivided into Yan101, Yan102, Yan103 and Yan104. Braided channel, core beach and flood-plain are the main sedimentary microfacies. The extension direction of Yan10 member sand body is north to south, and the whole channel sand body of the reservoir group is relatively developed, with large thickness, far extension and good connectiveness.
