Xiankang Xin, Zhou Fang, Gaoming Yu

There are obvious different with special percolation characteristics of low permeability reservoir and high permeability reservoirs, the seepage law is unique. Because of its unique characteristics, using suitable for middle and high permeability reservoirs theory technology development is bound to cause all sorts of problems. In this paper, in accordance with the special low permeability oilfield reservoir core, fluid percolation features of the corresponding nonlinear seepage flow model was constructed, and nonlinear percolation mathematical model for numerical simulation of the developed related numerical simulation software, further research and analysis of nonlinear seepage law characteristics of low permeability reservoirs.
