介绍了两性季铵内盐DMHSEA的合成 ,考察其在油田注水中的杀菌效果 ,并与目前常用的杀菌剂12 2 7、异噻唑啉酮进行性能对比。结果表明 :DMHSEA对SRB具有更强的杀菌能力
The synthesis of amphoteric quaternary ammonium salt DMHSEA was introduced to investigate the bactericidal effect of DMHSEA in waterflooding of oilfields. The performance was compared with the currently used fungicide 12 2 7 and isothiazolinone. The results showed that DMHSEA had a stronger bactericidal effect on SRB
