                 阻垢剂 PASP/3A4HBSA。用 FTIR 与 HNMR 对阻垢剂的结构进行了表征,用静态阻垢法考察了 PASP/3A4HBSA
                 和 PASP 对碳酸钙的阻垢性能。得到的最佳反应条件为:当阻垢剂质量浓度为 100  mg/L、温度为 70  ℃、时间
                 24  h、pH=7 时,PASP/3A4HBSA 对 CaCO 3 的阻垢率达到 92.7%,而 PASP 对 CaCO 3 的阻垢率只有 77.1%。用
                 SEM 与 XRD 对处理前后的 CaCO 3 垢样表面结构和物相结构进行了表征,用红外光谱进一步分析阻垢剂的阻垢
                 机理。结果表明,阻垢剂对 CaCO 3 的作用主要包括晶格畸变作用和络合作用。

                 Abstract:  Polyaspartic  acid/3-amino-4-hydroxybenzenesulfonic  acid  graft  copolymer  (denoted  as
                 PASP/3A4HBSA)  scale  inhibitor  was  synthesized  from  3-amino-4-hydroxybenzenesulfonic  (3A4HBSA)
                                                                   1
                 and  polysuccinimide  (PSI)  and  characterized by  FTIR  and  HNMR.  The  static  scale  inhibition  effect  of
                 PASP/3A4HBSA and polyaspartic acid (PASP) on calcium carbonate was investigated. The results showed
                 that when the mass concentration of scale inhibitor was 100 mg/L, temperature was 70  ℃, time was 24 h,
                 and pH was 7, the scale inhibition efficiency of PASP/3A4HBSA on CaCO 3 reached 92.7%, while that of
                 PASP was only 77.1%. The surface structure and phase structure of CaCO 3 scale samples before and after
                 treatment  were  characterized  by  SEM  and  XRD.  The  scale  inhibition  mechanism  of  the  scale  inhibitor
                 against CaCO 3 was further analyzed by FTIR. It was found that the effect of scale inhibitor on CaCO 3 was
                                                                                             2+
                 mainly caused by lattice distortion of CaCO 3 and complexation between scale inhibitor and Ca .

                 结垢对油气田生产造成的危害是十分严重的。                          CaCO 3 是油田结垢中最常见的物质,在水中的溶解
                                                                                                         [1]
            首先会降低油层渗透率,开采成本增加,油气产量                             度很低,用一般方法较难清除干净,危害很大 。
            下降;其次使井筒、管线、机泵的效率大大降低。                             采用阻垢剂来阻止结垢是油气田提高采收率、增加
