摘　　要：以丙烯酰胺(AM)、二甲基二烯丙基氯化铵(DMDAAC)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和N-乙烯基吡咯烷酮(NVP)为反应单体,以过硫酸胺、亚硫酸氢钠为引发剂,制备了一种新型的两性离子粘土稳定剂,并采用红外光谱对其结构进行了表征。结果表明,在40℃下,当引发剂加量为0.55%,AM∶AMPS∶DMDAAC∶NVP物质的量比为160∶20∶13∶2,反应时间为3 h时,所制备的四元共聚物AM/AMPS/DMDAAC/NVP防膨率可达90.74%,具有良好的耐温耐盐性及耐酸碱性能,可以有效防止粘土水化膨胀、分散运移,有利于降低采油成本,在油气田领域具有良好的应用潜力。Using acrylamide(AM),dimethyldiallylammonium chloride(DMDAAC),2-acrylamido-2-methylpropanesulfonic acid(AMPS) and N-vinylpyrrolidone(NVP) as reactions monomer,amine persulfate and sodium bisulfite as initiators,a new type of zwitterionic clay stabilizer was prepared,and its structure was characterized by infrared spectroscopy.The results show that at 40 ℃,when the initiator addition amount is 0.55%,the material ratio of AM∶AMPS∶DMDAAC∶NVP is 160∶20∶13∶2,and the reaction time is 3 h,the prepared quaternary copolymerization.The anti-swelling rate of AM/AMPS/DMDAAC/NVP can reach 90.74%.It has good temperature resistance,salt resistance,acid and alkali resistance,and can effectively prevent clay from hydrating and swelling,dispersing and migrating,which is beneficial to reducing oil production costs.In oil and gas fields has good application potential.
