摘　　要：储采比是油田规划和油田开发效果评价的重要指标,国内学者对储采比预测模型进行了深入的研究。本文首先对各种预测模型进行对比分析,分析结果表明对于单个油藏,A rps递减模型更能反映油藏本身的特点和渗流特征,然后对其理论基础和数学推导过程进行研究,在此基础上提出了适用于递减期的油藏储采比预测模型。通过具体油藏的实际应用表明,本文推荐的模型预测结果较好。Reserves-production ratio is an important indicator on development planning and evaluating development effect.Reserves-production ratio forecasting models have been deeply researched and studied by domestic experts.Through analyzing forecasting models it can be concluded that Arps decline model can reflect characters of the reservoirs and the percolation.The discussion of this models' basis of theory and analytical procedure of derivation are also addressed in the paper.On top of those results,we develop a new forecasting model which is suitable to forecast the reserves-production ratio of reservoirs in the production declining stage.The new model is able to obtain a more precise forecasting result,proved by its application on a practical reservoir.
