Abstract: This paper presents an approach for computer to automatically simulate typical curves of petroleum development models based on the optimum theory. The principle of automatic simulation analysis is provided in detail. Using the improved annealing simulation algorithm, full-scale solution of optimal equation is obtained with flow chart for programming. This approach can deal with the problem of the typical curves, and can be applied to estimation of monotone decreasing type and peak shape declining of reservoir production.
