摘要

摘要: 为解决200℃高温酸化用工作液对井下管柱腐蚀风险问题，运用高分子合成方法形成了一种以曼尼希碱季铵盐为主剂，炔醇衍生物、无机盐为增效剂，醇溶剂、分散剂为辅剂的新型复合酸化用缓蚀剂。引入炔醇衍生物替代丙炔醇，毒性降为低毒，且缓蚀剂溶解分散性好。运用高温高压动态腐蚀评价方法开展室内评价，缓蚀剂加量为5.5%，15% HCl在200℃下腐蚀速率低于60 g/（m²·h），20% HCl的腐蚀速率低于70 g/（m²·h）；缓蚀剂与15%盐酸在200℃下配伍性良好，酸液体系腐蚀速率仍低于70 g/（m²·h），电化学腐蚀结果表明加入缓蚀剂的酸液电流密度低至6.07×10^-6 A/cm²。缓蚀剂的缓蚀速率随主剂、增效剂加量的增加而降低，随酸浓度、稠化剂加量的增加而增大；缓蚀剂的电化学评价结果表明加入复合缓蚀剂酸液电流密度低，具有较好的缓蚀效果，加量达到一定程度后增加用量不能进一步提升缓蚀效果。

Abstract: inhibitor for use in acidification fluids has been developed to deal with corrosion to downhole tubular goods by acids at 200℃. The synthesis of this corrosion inhibitor involved the use of Mannich base quaternary ammonium salt as the main additive, an alkynol derivative and an inorganic salt as the synergists, and an alcohol solvent and a dispersant as the auxiliary additives. The introduction of the alkynol derivative (to replace propynol) into the corrosion inhibitor can minimize the toxicity of the corrosion inhibitor and render it good solubility and dispersity. Laboratory evaluation of the corrosion inhibitor using high temperature high pressure dynamic corrosion evaluation method showed that a fluid containing 15%HCl has corrosion rate less than 60 g/(m²·h) at 200℃ if the fluid was treated with 5.5% corrosion inhibitor. If the concentration of the HCl was increased to 20%, the corrosion rate was less than 70 g/(m²·h). The 15% HCl acid fluid has good compatibility with other additives. Electrochemical corrosion test showed that an acid treated with the corrosion inhibitor has electric current density of 6.07×10^-6 A/cm². The corrosion inhibition efficiency of the corrosion inhibitor decreases with increase in the amount of the main additive and the synergists used, and increases with the increase of the acid concentration and the amount of the thickening agent used. Electrochemical evaluation of the corrosion inhibitor showed that addition of the corrosion inhibitor reduced the electric current density of the acid fluid; when added into the acid to a certain concentration, the corrosion inhibition efficiency will not be further improved.
