摘要: 采用氧化还原体系以2-丙烯酰胺基-2-甲基丙磺酸(AMPS),丙烯酰胺(AM),等乙烯基单体为基本原料合成出了新型抗高温二元共聚物PAX系列处理剂。该降滤失剂在220℃的高温下及饱和盐水中具有良好的降滤失作用。

Abstract: A newstyle thermostable binary copolymer filtrate loss reducer-PAX, has been synthesized by 2-acryloyl-2-methyl-propylsulfonate (AMPS) and acryamide (AM) under a redox system. Results have been shown that PAX possesses good effect on reducing fluid loss under 220℃and saturated brine media.

Key words: filtrate loss reducer, synthesis, drilling fluid, deep well slurry
