The Network Simulation Research about Relative Permeability Curves of the Reservoir with Different Characteristics

Three-dimensional network model composed of pores and throats is built randomly by using computer simulation.The fluid flow in the model is researched,and the method to solve the relative permeability is set up.Then,due to three kinds of reservoir structures such as high porosity and high permeability,high porosity and medium permeability,and low porosity and low permeability,different network models are built.And using it as a platform,relative permeability curves of different characteristics reservoir structures are solved by network simulation.Finally,the characteristics of these curves are analyzed and the reason is also interpreted.
