本文通过使用压力恢复偏移无限作用情况的资料,扩大了识别非流动边界影响的方法,无因次压力衰竭系数由准确的原始油藏压力,Horner 图上的外推压力和无限作用数据的斜率作为参数组成。以 Horner 曲线上的中、晚期斜率比值为纵座标,Horner 时间为横座标绘制对应关系曲线。该曲线与已知无因次压力衰竭系数值和边界外形的那些曲线所对应匹配。对实际油田的分析是用计算结果来说明这种方法的 In this paper, the method of identifying the influence of non-flowing boundary is expanded by using the data of the infinity action of pressure restoration offset. The factor-free pressure failure coefficient is calculated from the exact original reservoir pressure, extrapolation pressure on Horner plot and slope of infinity data As a parameter. The mid-to-late slope ratio on the Horner curve is taken as the ordinate and the Horner time is plotted on the abscissa. This curve matches the curves corresponding to known values ​​of the dimensionless pressure failure coefficient and the shape of the boundary. The actual field analysis is calculated using the results of this method
