Scientific output prediction is very important for the development in oilfield. This paper combines Γ model with the water drive curves and presentes a new predicting model based on the combined solution of Γ model and water drive curves to predict the integrated indices varied with production time in oilfield. The model gets over the limitations of individual prediction using Γ model and water drive curves. It is convenient to use the combined solution models for predicting the development indices, such as water content ratio, oil production and cumulative production. The predicting results using real developing data show that combined solution models combining Γ model with water drive curve A and water drive curve C are better than others. Based on comparison and analysis using combined solution models for predicting the development indices in oilfield, the practicality and effectiveness combined Γ model with water drive curves have been approved and they can be satisfied for dynamic predicting development indices in water drive oilfield.
