摘要
对于复杂边界、多变的非均质性油气藏及多相流试井等问题,以解析法为基础的常规试井分析方法已无法得到解决,而数值试井的分析方法可望得到很好的解决。本文通过对数值试井分析方法的调研,介绍了数值试井的主要分析方法,包括有限差分法、有限元法和边界元法等。最后系统地比较了三种方法的优缺点以及适用范围。
Well testing and other issues of complex boundary,changing heterogeneity reservoir and multiphase flow can not be resolved by conventional well test analysis methods based on the analytical method.However,the numerical well test analysis method is expected to be a well solution.In this paper,through research on the numerical well test analysis,main methods of numerical well test analysis were introduced,including the difference method,the finite element method and the boundary element method.Finally,advantages and disadvantages of three methods were systematically compared as well as their application scope.
