With the deepening of oilfield development, the old oil field comprehensive moisture content is higher and higher and reservoir parameter has changed, that the conventional means of quantitative analysis of the condition of reservoir water flooding research has can't meet the requirements, so this needs to carry out the water flooded layer research new methods and new theory. In this paper Fisher discriminant method of multivariate statistical analysis is used to establish a new water flooded layer interpretation model, that the coincidence rate of Off-balance-sheet reservoir is 78.3% and the coincidence rate of in the table of the reservoir is 81.3%, which effectively improves the water flooded layer discriminant accuracy.
