ARGIN: 0cm 0cm 0pt" class=MsoNormal>ang=EN-US>By assuming the conductivity way between different pore types, the method of establishing a reasonable porosity model and further combining with Archie equation to calculate water saturation is a conventional way. In the previous dual-porosity model, the effect of fracture dip and fracture tortuosity was not considered. The authors provide an improved porosity model varied with fracture dip and fracture tortuosity to reprocess the exponent index m and water saturation in fractured reservoir. By contrast with the core analysis data, the improved porosity model is more reasonable, and it maybe leads to a relative error of 32.1% while using the previous porosity model.amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
