摘要： 丙烯酰胺与含磺酸基单体的共聚物用于提高石油回采率已有不少报道,如乙烯基磺酸、丙烯酸磺丙酯、苯乙烯磺酸、2-丙烯酰胺基-2-甲基丙磺酸和甲基丙烯酸磺乙酯。亦有文献提到用丙烯酰胺与烯丙基磺酸钠共聚物,但缺乏详细报道。国内油田钻井液处理剂中的PAC142和PAC143是丙烯酰胺、烯丙基磺酸钠及其它单体的多元共聚物;日本的钻井液处理剂G-20LL是丙烯酰胺、烯丙基磺酸钠和丙烯酸的三元共聚物。本文报道丙烯酰胺与烯丙基磺酸钠的共聚合及产物的絮凝性能。

Abstract: Water-soluble copolymers of acrylamide with sodium allylsulfonate were prepared in aqueous solution using ammonium persulfate as initiator. The monomer reactivity ratios (γ1=2.67,γ2=0.31,30.0℃) were calculated by Kelen-Tudos method and Finoman-Ross method. The experimental results with kaolin suspension showed that the copolymers possess a good flocculatability and resistance to salt and acid.

Key words: acrylamide, sodium allylsulfonate, copolymer, flocculation
