According to the waterflooding characteristics in extra-high water cut stage of oilfield, a calculation model which is based on profit and loss balance principle has been created. This model can be used to identify the economic limit water cut of producers with different cost component. With the use of this model, the economic limit water cut in a development block of Daqing Oilfield with different oil prices has been calculated, and according to the economic benefit, producers have been classified into different group. This model is a significant basis of well shut-in and oil-field development.
