Abstract: According to the layered existing in Toutai oilfield, Fuyu oil reservoir is divided into 18 layers, and the "area, many faults, well spacing density differences compared with" problem "of high resolution sequence stratigraphy" and "fine sedimentology" theory, put forward the "regional skeleton closed profile based standard layer under the control of thick sand combination marks, sedimentary model of contemporaneous fault mode - guidance, step by step first approximation comprehensive comparison, and gradually progressive partition closed open, method of reservoir comparison finally causes shift sector', Toutai oilfield, Mao 10、 Mao 11 layered unification, based on respect for the original hierarchical division, single sand body levels on the formation of the Fuyu region, the original 18 layer segment to 34 sedimentary units, and of all the 566 wells were all well integrated and unified contrast, establish the research area Uniform and fine small level stratigraphic framework, for the plane microfacies and single sand body identification, reservoir connectivity, similar layer sand body distinction, stacked sand distinguish and plane heterogeneity, fault identification laid a solid foundation for the geological.
