通过水溶液聚合,制得了降粘剂丙烯酰胺/2-丙烯酰胺基-2-甲基丙磺酸/衣康酸共聚物( AAI),研究了单体配比、反应时间、反应温度、pH等的影响。结果表明,合成降粘剂的优化方案为:AM:AMPS:IA为1:2:2,反应时间4 h,反应温度80℃,pH为6,单体浓度为20%,引发剂加量为单体总质量的0.3%。在淡水钻井液中加入0.3%共聚物,降粘率可达94.4%;且在220℃老化16 h后,降粘率仍达53.4%。在加入FA367的聚合物钻井液中加入0.3%共聚物,降粘率可达90.4%;在220℃老化16 h后,降粘率仍达50%,同时具有较好的抗盐性。

A copolymer( AAI)of acrylamide,2-acrylamido-2-methylpropane sulfonic acid and itaconic acid is prepared in aqueous solution. The effect of monomer ratio,aspect of reaction time,temperature, pH,etc. on polymer viscosity reducer was investigated. Result shows that the synthesis thinner optimization program are as follows:AM:AMPS:IA is 1:2:2,reaction time 4 h,the reaction temperature is 80 ℃,pH 6 ,the monomer concentration of 20%,plus the amount of initiator the total mass of the monomer of 0. 3%. Adding 0. 3% copolymer viscosity into fresh water base mud,the rate of reduction is 94. 4%;and after aging 16 h at 220℃,the reduction rate still reached 53 . 4%. Adding 0 . 3% copolymer viscosity into FA367 polymer drilling fluid,the reduction rate is 90. 4%;and after aging 16 h at 220 ℃,the reduction rate is still 50%,also has good salt resistance.
