摘要: 针对双渗油藏的渗流特征,在两渗流层之间存在流体的交换;以往的双渗油藏并没有考虑流体之间的渗流,仅仅将两层之间的流体交换作为源和汇;在此考虑了两层之间渗流耦合的微分方程及压差对两层的影响,对方程采用无因次化,而将方程简化。通过正交变换获得该模型的精确解,该解对理解双渗油藏的渗流规律和试井分析都具有重要的指导意义。

Abstract: According to percolation theory of reservoir with flow in porous media , there is exchange between fracture and matrix. The flow in porous media between layers is not considered before. This paper considers differential equation between two layers reservoir. In this paper , analytic solution of the model
gained through orthogonal transformation. This solution is very important for well testing analysis.

Key words: reservoir with dual flow porous media, couple model, differential equation, well testing analysis
