Abstract  In order to further improve the prediction level of perforation and the effect of engineering application, based on the theory of percolation mechanics and the equivalent of two sets productivity formulas for open hole completion, this paper derives the permeability calculation model of perforating belt.Through the calculation of the actual perforation parameters,the following conclusions are drawn.The permeability of perforation belt is positively correlated with penetration ratio,perforation radius and perforation density.The dominant effect of penetration depth ratio,perforation density and perforation radius on the permeability of perforation belt decreases in turn.The accuracy of the formula can reach 90%,which can guide the field application.

射孔带渗透率计算式的推导与应用

为进一步提高射孔的预测水平及工程应用效果,基于渗流力学理论及等效两套裸眼完井产能公式,推导了射孔带渗透率计算式。给定实际射孔参数,经计算得到:射孔带渗透率与穿深比、孔眼半径、射孔密度呈正相关;穿深比、射孔密度、孔眼半径对射孔带渗透率的影响依次减小。实测验证得到,模型的计算精度可达90%,对现场应用具有一定指导作用。
