摘要
研究了自制丙烯酸十八酯、苯乙烯、马来酸酐和丙烯酰胺4种单体分别以物质的量比10∶3∶2∶0.8和6∶1∶2∶0进行四元无规共聚反应,得到两种新型油溶性的共聚降粘剂。对溶剂用量、反应温度等影响条件进行了优化,探究了降粘剂用量和温度等因素对降粘效果的影响。结果表明,四元共聚物的降粘效果优于三元共聚物。50℃,当降粘剂的加入量占稠油量的10 wt%时,三元和四元共聚物对稠油的降粘率分别达79.4%和87.6%。
The novel oil-soluble copolymerization viscosity depressants were synthesized by octadecyl acrylate,styrene,maleic anhydride（MA） and acryl amide with the molar ratio of 10∶ 3∶ 2∶ 0. 8 and 6∶ 1∶ 2∶ 0. The dosage of solvent and synthesis temperature affecting the rate of viscosity were optimized. The effects of copolymerization viscosity reducers dosage and temperature were investigated. The results indicated that the effect of viscosity reducing of quaternary copolymer was better than that of the ternary polymer. At 50 ℃ and viscosity agent dosage of 10 wt%,the rate of viscosity reduction of ternary and quaternary copolymers were79. 4% and 87. 6%,respectively.
