摘要
建立了考虑流体粘度在径向上变化的多重组合油藏试井分析模型 ,应用拉氏变换对数学模型求解 ,得到一个拉氏空间的多元线性方程组 ,采用解线性方程组的LU分解法及数值反演技术 ,求得了井底压力的实空间解 ,并给出了用于试井分析的典型曲线。应用本模型可对聚合物驱或三元复合驱等流体性质变化的油藏的试井资料进行分析。
This paper builds up a well testing analysis model of multiple combination reservoir considering the radial change of fluid viscosity.By applying Laplace change to resolve the mathematic model,a multivariate system of linear equations in Laplace space has been got and the real space solution of down hole pressure has been gained by using LU disintegration method and numerical inverse technique for resolving system of linear equations and a typical curve has been given out.By use of this model,the analysis can be done to the well testing data of the reservoir with fluid property change of polymer flooding or alkali-surfactant-polymer flooding.
