    摘要:

    本文在用粘弹性流体本构模型描述三元复合驱地层流体流变特性的基础上,建立了三元复合驱地层流体在地层中渗流的基本微分方程,采用有限差分法对其进行了数值求解,并用拉格朗日插值法对产能进行预测,分析了流体的流变参数对产能的影响。通过对大庆油田采油四厂5口油井的产能预测结果与实测结果进行对比分析,其相对误差在20%以内,表明用粘弹性流体本构模型来描述地层流体的流变性能较好地预测油井的产能。

    Abstract:

    Based on description of the rheological characteristics of ASP combination flooding formation fluid using the constitutive model of viscoelastic fluid, the basic differential equations of flow of ASP reservoir fluid in porous medium were established and numerically calculated using finite differential method, on the works of above mentioned, the productivity of ASP oil well was forecasted using Lagrange interpolation method, the rheological parameters which affected productivity of ASP oil well were analyzed in this paper. By means of relative analysis of the results of theoretical arithmetic and the measured data of 5 oil wells of the forth oil recovery factory in Daqing, the percentage of error is less than 20%, the results indicate that the method using rheology of ASP reservoir fluid which is described using viscoelastic fluid constitutive equation model can predicated productivity of ASP oil well very well.
