| 摘 要： | 以水溶性季铵盐、水解聚马来酸酐、聚环氧琥珀酸钠、聚天冬氨酸为原料,复配了一种新型缓蚀阻垢剂BW-3。BW-3具有优异的阻垢性能和良好的缓蚀效果。在所测浓度范围内,BW-3的阻垢和缓蚀效果均明显优于油田常用缓蚀阻垢剂;电化学试验结果表明,BW-3的缓蚀机理属于"负催化效应",是一种以抑制阴极反应过程为主的混合型缓蚀剂。BW-3对CaCO3垢的阻垢机理主要是晶格畸变作用。

| Abstract: | A new corrosion inhibitor BW-3 has been prepared by using water-soluble quaternary ammonium salt,hydrolytic polymaleic anhydride,polyethylene succinate,polyaspartic acid as raw materials.BW-3 has excellent anti-scaling performance and good corrosion effect.Anti-scaling performance and corrosion performance of BW-3 are significantly better than the corrosion inhibitors which have frequently used by oilfields.Electrochemical test results show that the corrosion mechanism of BW-3 is a"negative catalytic effect" and a mixed type of corrosion inhibitor which mainly inhibit cathode reaction.The inhibiting mechanism of CaCO3 scale by BW-3 is,mainly lattice distortion function. |
