The permeabiligy of fracturing sand has an effect on fracturing result straightly, as the productivity increase by fracturing is due to the highly permeable sand bed, which is newly formed by packing fractures with sand, and more oil moves along easier into the well bore. In this paper the discussion is made on factors controlling the permeability of fracturing sand, and on the method of obtaining the fracturing sand permeabiligy. The comparatively good coincidense is obtained between experimental values and calculated values of fracturing sand. However, suitable value of sphericity factor must be counted.
