摘要
利用流体力学理论，导出了两种非牛顿流体在偏心环空中轴向层流顶替的数学模型，并利用数值方法求解了该模型。最后得出结论：增大水泥浆密度、泥浆流性指数、水泥浆稠度系数、流量，降低泥浆密度、水泥浆流性指数、泥浆调度系数等，都有利于提高注水泥顶替效率。
Using the fluid mechanics theory, a mathematical model for non-Newtonian fluids about the axial laminar displacement in an eccentric annulus is proosed out, and using the numerical method the model is mace out.Lastly, it is obtained that the displacement efficiency can be enhanced by increasing the density of cement slurry,the index of mud flow behavior, the consistency index of cement slurry and the flow rate,decreasing the mud density,the index of cement slurry flow behavior and the mud consistency index.
