- W2378771768 abstract "HPAM removal of cationic macro-polymer in produced water was studied,effect of cationic polymer on HPAM shape in produced water was investigated by means of scanning electron microscope(SEM) and transmission electron microscope(TEM).The research found cationic macro-polymer could remove HPAM,and the effect of CJSG-cationic polymer was the best.Laboratory and oilfield experiments show 3mg/L CJSG can achieve over 64% of HPAM removal ratio in polymer flooding produced water in Xiaermen Area of Henan Oilfield,and light penetrating ratio of water treated by floc-settling technique can achieve approximately 90%.The electron microscopic analysis indicates HPAM and CJSG in water exist in different shapes,and the shapes are independent of water saliferous quantity.HPAM exists in line-type chain(sheaf) shape,and CJSG has a string beads(granule) shape,but admixture of HPAM and CJSG exist in a string beads(granule).HPAM hydrodynamics dimension and HPAM solution viscosity reduce by adding CJSG,and HPAM removal ratio in water goes up.The mechanism of CJSG removing HPAM is that CJSG changes the shape of HPAM in water,decreases hydrodynamics dimension of HPAM and the solution viscosity as well as its dissolving ability,and enhances HPAM removal ratio in air-floatation." @default.
