%X At present three main reservoirs in Tuha oil field have been in middle or high water-cut stage. According to the fluid flow properties of high water-cut stage, refined predicting model for formation was constructed on the basic of researches of high resolution sequence stratigraphic correlation and depositional microfacies. Residual oil saturation between wells and layers was obtained by using new technique such as boron neutron lifetime log, RST,CHFR and pressure maintenance sealing coring; Residual oil distribution in formation was studied in detail by making use of numerical simulation and integrated analysis. It result demonstrates that potential room is little because the characteristic of water flooding in layers is similar and sweeping thickness coefficient is high in different rhythm layers to watered out formation; it is a enrichment and rooting potential zone because the residual oil allocates at a certain area between producing wells and injection wells to highly heterogeneous information that is a great different in water injectivity and properties vertically. The research on residual oil distribution of high water-cut stage is an important aspect of adjustment of development strategy and EOR for a mature oilfield.
