【 摘 要 】

Chemeor software is the only application of chemical flooding analog and digital simulation software in our factory at present. Viscosity parameter is the most important parameter affecting water cut and ultimate recovery in software. The polymer viscosity at zero shear rate is used in calculating viscous concentration parameters. Usually, after artificial shearing, the viscosity parameters of polymer are estimated, which are in accordance with the actual production. Because it is impossible to give a more accurate shear coefficient, Often, the initial calculated viscosity is quite different from the actual one. It has caused great difficulties for subsequent adjustment. In this paper, the shear behavior under different injection systems is discussed. Finally, the optimum initial operating viscosity shear coefficient is determined.
