【Abstract】 The Copolymer (AM/AA/AE) of (poly-oxylethylene alkylphenyl ether) acrylate (AE), acrylamide (AM) and acrylic acid (AA) were synthesized with peroxide as initiator and water was solvent. The effects of monomer concentration, the reaction temperature on special property viscosity of AM/AA/AE were discussed. The effects of copolymer AM/AA/AE concentration on the flow characteristics (pour point, apparent viscosity) of wax-bearing crude and on alkaline tolerant of high salinity and hardness were discussed. It was found that the flow characteristics (pour puint, apparent viscosity) of way-bearing crude can be improved appreciably by adding a copolymer of AM/AA/AE. The copolymer of AM/AA/AE exhibited the better tolerant properties of high salinity and hardness.更多还原
