配置原油模拟液，研究了二乙基二硫代氨基甲酸钠（SDDTC）于模拟液中单独使用及其分别与硫酸锌，铬酸钠的复配对316L钢的缓蚀效果。实验表明：在高酸高氯环境下SDDTC能够很好的抑制316L钢的腐蚀；而且SDDTC与硫酸锌，铬酸钠之复配缓蚀剂具有很好的协同增效作用，这一切相关研究具有重要的实际应用意义。

The corrosion inhibition behaviors of 316L steel using the sodium diethyl dithiocarbamate (SDDTC) compound in the crude simulation solution were studied in the absence and presence of zinc sulfate or sodium chromate with different compositions. Experiment resultss showed that in the environments of highly acidic and high concentrations of chloride ions the SDDTC compound could well inhibit the corrosion of 316L steel. The good synergic effects on the corrosion inhibition of 316L steel by additions of either zinc sulfate or sodium chromate into SDDTC compound were indicated in this study, which is of great significance and importance in practical applications.
