Research On Viscosity Stability Of Polymer Solution Made Up By Sewage

This thesis had studied the viscosity of polymer solution from the preparation of different water quality and retention rate after a certain period of the aging of the viscosity. the stabilizer prepared by different water quality was added into different concentrations of polymer, and laboratory experiment was carried out to evaluate the stability of polymer after different digestion time.The effect of stabilizer on rheology behavior,storage modulus,Energy consumption modulus,resistance factor and residual resistance factor of polymer and the change of viscosity of polymer solution when different stabilizers were added into it had been analyzed. A good oil displacement system had been screened, and the effect was the best when the concentration of stabilizer was between 100mg/L-120mg/L ,and the the effect of experiment in lab and in place was assessed. The result of application I place showed that: the stabilizer can increase the viscosity of polymer which was diluted with anaerobic sewage and keep it for a long time. The effect of oil displacement can be improved, and slow down the aqueous speed, and save polymer Dry powder. By doing this ,we can get a good economic benefits...
