Abstract: To properly predict the output of an oil and gas reservoir is of great importance for improving the production effect of the reservoir and enhancing the effect of reservoir stimulation.Based on the control theory, the performance indexes of an oil and gas reservoir can be accurately predicted using suitable function simulation model.The theoretical bases of some stationary function simulation models are described.The gas production of the volatile oil reservoir of Shuangyang oilfield is predicted in initial stage of development, choosing an AR model of a random sequence in which the average value is not zero.The prediction precision of the model is up to the engineering requirements.
