针对油水生产的实际过程,综合考虑了启动压力梯度、储层介质的分形及油藏和井筒的耦合流动,将油藏渗流与井筒管流作为整体来研究,建立了分形低渗透油藏-井筒耦合流动模型。采用IMPES方法对模型进行离散,应用追赶法求解,得到井口定产量生产、定压外边界情况下,分形低渗透油藏-井筒耦合的一个计算示例的数值解,分析和讨论了参数对压力动态的影响。
Considering the actual process of oil and water production, considering the start-up pressure gradient, the fractal of reservoir medium and the coupled flow between reservoir and wellbore, reservoir seepage and wellbore flow were studied as a whole. Fractal low permeability reservoir - wellbore Coupling Flow Model. The IMPES method is used to discretize the model and the chase method is used to solve the problem. The numerical solution of a computational example of fractal and low permeability reservoir-wellbore coupling is obtained when the wellhead output is fixed and the outer boundary of constant pressure is obtained.
