【摘要】 低渗透油藏油井的流入动态分析对低渗透油田的合理开发和科学管理具有重要意义。为此，本文根据低渗透油田的渗流规律和油藏介质特征，以渗流力学理论为手段，对低渗透油藏油井的流入动态(IPR)预测方法进行了深入研究。基于考虑启动压力梯度和介质变形特性的单相流渗流方程，建立了适应于低渗透油藏油井的产能方程，并给出了低渗透油藏单相流IPR预测方法。对多相流动情况，对沃格尔方程直接应用于低渗透油藏进行了误差分析，建立了考虑启动压力梯度的修正沃格尔方程，给出了低渗透油藏两相流产能方程及IPR预测方法，并对低渗透油藏IPR曲线特征的影响因素进行分析。 针对运用垂直裂缝井开发的低渗透地层，根据Cinco-ley提出的垂直裂缝井压力动态预测方法，提出了适用于垂直裂缝井的IPR预测方法，并结合应用实例对各个敏感因素进行了分析。更多还原

【Abstract】 Studies of inflow relationship aimed at characteristic of low permeability reservoir have great significance for its development and management. Based on flow principle and the characteristic of low permeability, this paper made a deep study of IPR forecasting method. Based on the flow equation concerned on threshold pressure gradient and deforming media, this paper productivity equation and IPR forecasting method for low permeability reservoir. Error analysis when Vogel equation was applied to low permeability was presented in this paper, we also derived productivity equation and IPR curve for double phase flow.Aimed at the vertical fractured well in low permeability, based on the pressure response forecasting method presented by Cinco-ley, this paper shows a method of IPR and productivity forecasting, we also analyzed the sensitive factors for IPR curve of a vertical fractured well.更多还原
