摘　　要：针对油气生产的实际过程,不仅考虑了储层介质变形对储层渗透率的影响,而且考虑了油藏与井筒的耦合流动,将油藏渗流与井筒管流作为整体来进行研究,建立了变形介质油藏-井筒耦合流动模型。采用无条件稳定的全隐式方法对模型进行离散,应用Newton迭代方法求解,得到井口定产量生产时,定压外边界情况下,变形介质油藏-井筒耦合流动模型一个计算示例的数值解,并绘制了压力图版。In combination with oil and gas production process, not only the effect of medium deformation in reservoirs on permeability, also the coupled flow of reservoirs with wellbore are considered. The seepage flow in reservoirs and pipe flow are considered as a whole in the study. A model of coupled flow in deformation medium reservoir flowing with wellbore is established. An unconditionally stabilized full implicit method is used for discrete processing, and Newtonian iterative method is used for solution, by which a numerical solution of calculation example of the model of coupled flow in deformation medium reservoir flowing with wellbore is obtained for external boundary condition of constant pressure for the production with constrain wellhead rate, and chartboard of pressure is plotted.
