| Abstract: | This paper examines the two-phase flow for a horizontal well penetrating a naturally fractured reservoir with edge water injection by means of a fized streamline model. The mathematical model of the vertical two-dimensional flow of oil-water for a horizontal well in a medium with double-porosity is esta-blished. and whose accurate solutions are obtained by using the characteristic method. The saturation distributions in the fractured system and the matrix system as well as the formula of the time of water free production are presented. All these results provide a theoretical basis and a computing method for oildisplacement by edge water from naturally fractured reservoirs. |
