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.%通过随机方式建立由孔隙和喉道组成的三维网络模型,研究流体在模型中的流动,建立求取相对渗透率的方法。在此基础上,针对高孔高渗、高孔中渗和低孔低渗三种不同的储层结构,分别建立与其对应的网络模型。通过网络模拟方法求取不同特征储层的相对渗透率曲线。
