摘　　要：以辽河油区已投入吞吐开采稠油油藏实际开发数据为基础，总结出了年油汽比变化规律，建立其动态预测的数学模型，并用推广递推梯度方法，对模型中的参数进行了估计。Oil-steam ratio is one of the important indices in the evaluation of a development program for a heavy oil reservoir. The cycle of steam stimulation has been used as a standard for studying variation of OSR for many years in actual operation and in numerical simulation. For solving the problem of the development indices in planning and in prediction, practical development data of Liaohe oil field operation are studied in this paper to summarize the variation of annual OSR. At the same time a mathematical model of behavior prediction has been presented, and the parameter of model has been estimated by a generalized stepwised gradient method.
