高速下聚合物溶液阻力系数的研究

本文回顾了前人关于聚合物溶液在孔隙介质中流动的研究。早期的研究者认为，聚合物溶液在高流速条件下呈膨胀性。未有人就残余阻力系数和有效粘度对阻力系数的贡献提出意见。作者重复了流动试验，根据测试的FR一V和FRr一V曲线，计算了有效粘度，对比了残余阻力系数和有效粘度对阻力系数的贡献，并提出，高速条件下，高盐度的聚合物溶液呈膨胀性，低盐度的溶液仍可能呈假塑性。溶液的盐度愈高，高速下的有效粘度愈大。

THE STUDY OF RESISTANCE FACTORS OF POLYMER SOLUTIONSAT HIGH VELOCITIES

Experimental studies of the flow properties of polymer solutions in porous media by former investigators are reviewed in this paper. They suggested that polymer solutions exhibit dilatant behaviors at higher rates. However, the contribution of FRr and to resistance factors (FR) has not been evaluated. Based on the FR-V and FRr-V correlation data that were obtained from the flow tests performed by the authors, has been calculated, and the contributions of FRr and to the resistance factor have been compared. It is suggested that polymer solutions of high salinity exhibit dilatant behavior at high velocities, while those of low salinity probably exhibit pseudo-plastic. The higher the salinity of the solution, the higher the effective viscosity.
