摘要
Abstract
The hydrodynamic size of partially hydrolyzed polyacrylamide(HPAM) was determined by the microporous membrane method. The infl uences of fi ltration pressure,mass concentration of HPAM,its relative molecular mass,injected water or reinjected wastewater,and shearing strength on the hydrodynamic size were investigated. The results indicated that,when fi ltration pressure was 0.08 MPa,the HPAM hydrodynamic size increased with increasing the relative molecular mass and concentration of the HPAM. The higher the salinity of the injected water and reinjected wastewater, the smaller the HPAM hydrodynamic size. The mechanical shearing action had obviously eff ect on the hydrodynamic size of HPAM with low concentration. The hydrodynamic size can be used as a basis for the judgment of the fi t between polymer fl ooding and pore throat,which can guide the optimization design of oilfi eld polymer fl ooding projects.关键词
