摘 要:本文讨论了田菁减阻液的试验研究结果,即雷诺数、浓度、管径、机械降解及阳离子等因素对田菁减阻性能的影响。还探讨了紊流减阻的机理及介绍了田菁减阻液在岩心钻探中的初步应用效果.
Abstract: Using sesbania gum as the turbulent-drag-reduction solution, the effects of Reynolds number, concentration, diameter of pipe, molecular weight, mechanical degradation, ion and other factors on drag reduction have been studied in this paper. This paper also probed into the mechanism of turbulent drag reduction and introduced its preliminary application to core drilling.
