The retarding side effect and the compatibility with other additives are the main problems that limit the field application of the synthesized fluid loss control additive (FLCA). The effect of the type and content of carboxylic acid groups on the retarding side effect of FLCA and the compatibility between FLCA and the retarder AMPS-IA synthesized using 2-acrylamido-2-methyl propane sulfonic acid (AMPS) and itaconic acid (IA) was studied in this paper. The type and content of carboxylic acid group have a great influence on the fluid loss control ability, the compatibility with retarder and the retarding side effect of FLCA. FLCA containing IA or maleic acid (MA) shows better compatibility with retarder than FLCA containing acrylic acid, but the retarding side effect of FLCA containing MA is weaker than that of FLCA containing IA. Thus, MA is the most suitable monomer for synthesizing FLCA having good compatibility with retarder AMPS-IA.
缓凝副作用以及与其他添加剂的相容性是限制合成降滤失剂（FLCA）现场应用的主要问题。本文研究了羧酸基团的类型和含量对FLCA缓凝副作用的影响以及FLCA与由2-丙烯酰胺基-2-甲基丙磺酸（AMPS）和衣康酸（IA）合成的缓凝剂AMPS-IA之间的相容性。羧酸基团的类型和含量对FLCA的降滤失能力、与缓凝剂的相容性以及缓凝副作用有很大影响。含IA或马来酸（MA）的FLCA与缓凝剂的相容性优于含丙烯酸的FLCA，但含MA的FLCA的缓凝副作用比含IA的FLCA弱。因此，MA是合成与缓凝剂AMPS-IA具有良好相容性的FLCA的最合适单体。
