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.
