摘要
采用有限差分方法获得低渗透油层低速非达西渗流有效井径数学模型的数值解;绘制了无限大地层、有限封闭地层、有限定压地层等三种外边界条件的典型曲线,讨论了典型曲线的特征。该新型典型曲线用于塔里木等油田试井资料解释取得了满意的效果。
The numerical solution of effective hole diameter mathematical model for low-speed NonDarcy flow in low permeability reservoir is obtained by finite difference method. The typical curves in three kinds of external boundary conditions of infinite formation,finite closed formation and finite constant pressure formation are drafted. The characteristics of the curves are discussed. A satisfactory result is obtained while interpreting the well-testing data of Talimu Basin by the new typical curves.
