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。
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.
