计算原油管路摩阻的一种新方法

Method for Friction Loss Calculation by the Aid of Measuring Pipeline Oil Rheology

分析幂律流体圆管层流流动特点，提出可用有效管流表现粘度及牛顿流体摩阻计算公式计算幂律流体的层流和紊流摩阻损失。针对热油管道工况特点，提出通过用旋转粘度计模拟测定管输原油流变性来计算摩阻的方法。

fter analyzing the performance of the laminar flow of a power law fluid in a circular pipe,it is found that thefriction loss of the power law fluid under laminar or tubulentflow state can be calculated by using the effectiveapparent viscosity of the pipe fluid and the friction factorequation for the Newtonian fluid.A method for evaluationgthe friction loss of oil flowing through a pipeline was presented with the aid of a rotary viscometer to imitate the pipeline oil rheology.
