摘要
利用封闭油藏衰竭式开采过程中地层压力随累积产油量的变化规律 ,建立了能够反映该变化规律的数学模型 ,对油藏的开采历史进行拟合 ,进而用地层压力降至废弃压力时的最大累积产油量来预测油藏的可采储量。经验证 ,该模型准确可靠 。
Using variation law of formation pressure along with cumulative oil production during natural depletion of a sealed reservoir,this paper creates a mathematical model, which may reflect such variation law, to try to match on reservoir production historyand furthermore to predict reservoir recoverable reserves with the largest cumulative oil recovery when formation pressure depresses to abandonment pressure.The verification proves the model is accurate and reliable and worthy of dissemination andapplication.
