摘　　要：针对高含钡地层条件,以有机酸A和有机酸B为主要原料,制备了防垢剂FX。考察了防垢剂加量、防垢时间、温度、氯化钠含量、体系pH值对高含钡地层条件下硫酸钡垢防垢效果的影响。结果表明,防垢剂FX是一种很好的硫酸钡垢防垢剂,当防垢剂FX加量为26 mg/L、体系pH 值大于9、温度小于70℃、防垢时间为18 h时,防垢剂FX的防垢率可达80%以上。A barium sulfate scale inhibitor FX for high barium - containing water was prepared with organic acids A and B as the main materials.The influences of scale inhibitor concentration,antiscaling time and temperature,NaCl concentration,and pH value on the efficiency of the inhibitor FX were studied.The results indicated that the antiscaling efficiency of the inhibitor was above 80% when the its concentration was 26 mg/L,pH was > 9, temperature was < 70℃, and time was 18 h.
