摘　　要：本文根据 Aronofsky等人由试验提出的产量递减模型 ,将采出程度与时间的关系模型转变为了阶段产量与时间的关系模型。由于每个裂缝性油藏有其本身的裂缝发育和裂缝展布特征 ,而不同的裂缝发育和展布特征必将导致油藏的递减规律也不相同。因此 ,当裂缝性油藏处于递减阶段时 ,应用上述模型能准确地预测产量递减规律和可采地质储量等。应用本文提出的预测模型 ,对阿北安山岩裂缝性油藏注水开发以来 ,产量递减阶段的数据进行了拟合和预测 ,与应用翁氏模型和水驱特征曲线两种方法分别预测的产量及可采储量对比 ,相对误差减小了 0 .0 1个百分点。实践结果表明 ,本文提出的产量预测模型适用于注水开发的裂缝性油藏的产量递减阶段 ,计算简单、快捷、相对误差小 。Based on the production declining model put forward by Aronofsky and the other people, We change the relationship between the time and recoverable rate into the time and the corrspond production. Sine every fractured reservoir has its own developing and extension characteristics, the law of production declining is definitely different. By using the model mentioned above, we can forecast the production and the recoverable reserves of fractured reservoirs during the declining time. By using the forecast model presented in this paper, we forecast the production and the recoverable reserves of Abei andesite fractured reservoir during the declining time sine water injection, comared the data with that come from the Weng model and water flooding characteristics curves, the relative error decreased 0.01 percent. The field practice classified that the model presented in this paper is adopt to the water flooding fractrued reservoirs during the production declining time. It is simple and quick calculated and the relative error is small, and it is utilizable to the oil field development and project compilation.
