The operating data from Daqing oilfield indicates that the viscosityloss of polymer because of fish eyes and shearing is about 40% more or less.
据大庆采油厂的运行数据表明:鱼眼、剪切造成的聚合物粘度损失大约为40%。

Under the same wall heat condition, with the increase of momentum correction coefficient, viscosityloss of the nozzle increases, but thrust and specific impulse decrease.
在同等壁面热条件下,随着动量调节系数的增加,喷管粘性损失增大,喷管的推力和比冲都将下降;

Daqing oil field prepared polymer solution with produced water from polymer flooding, and systematically studied the viscosityloss of polymer and the influencing factors.
