摘　　要：应用物质平衡原理建立多相渗流数学模型 ,通过定义拟函数将多相渗流方程变换为单相流体渗流方程相似形式 ,从而为多相流试井分析提供实用方法 ;分析讨论了利用相对渗透率曲线的拟函数处理方法在实际应用中所面临的困难 ,提出利用现场生产数据计算相对渗透率和拟函数处理的新方法。该方法所需相关参数少、计算稳定。通过软件实现与现场资料分析表明 。A mathematical model for multiphase porous flow has been established by using material balance theory. The multiphase flow equations have been transformed into the similar fashion of the single phase flow equations by defining pseudo functions. It can offer practical methods to the multiphase flow well test analysis. Problems are analyzed and discussed in practical application of pseudo functions using the relative permeability curves. An improved method for treating pseudo functions, using field data to calculate relative permeability, has been presented. The method has calculation stability and needs less correlation parameters. It has been shown that interpretation results are reliable by software realization and field data analysis.
