摘要
针对油藏的低渗透特征和油气实际流动过程,同时考虑油藏的分形特征,以及油藏和井筒耦合流动的影响,将分形油藏渗流与井筒管流作为整体进行研究,建立了低渗透分形油藏中非牛顿幂律流体径向渗流与井筒耦合流动模型。并采用差分方法求得模型的数值解。最后探讨压力动态变化规律,绘制压力图版。
In consideration of the actual production process of the oil and gas. A model of non-Newtonian power-law fluids in fractal reservoir coupled with wellbore is established. By using the finite difference method. The numerical solution is got to the infinitely large system with constant rate production. The effects of the parameters is also discussed to the pressure curves, such as the power-law exponent of the non-Newtonian power-law fluids, fractal parameters and double porous media parameters and chartboard of pressure is plotted.
