研究了丙炔醇（PA）在含0.2%醋酸的饱和CaCl2完井液中对超级13Cr不锈钢应力腐蚀开裂（SCC）的抑制作用。结果表明，在不添加抑制剂的情况下，超级13Cr钢易发生SCC。PA能在超级13Cr钢表面形成聚合保护层。低浓度PA提高了超13Cr钢的氢渗透率，加速了超13Cr钢的自晶化。高浓度PA降低氢渗透，有效抑制SCC。(C) 2012 Elsevier Ltd.版权所有。
The inhibition effect of propargyl alcohol (PA) on stress corrosion cracking (SCC) of super 13Cr stainless steel in CO2-saturated CaCl2 completion fluid in the presence of 0.2% acetic acid was investigated. The results indicate that super 13Cr steel is susceptible to SCC without addition of inhibitor. PA can form polymeric protective layers on super 13Cr steel. Low-concentration PA increases hydrogen permeation and accelerates SCC of super 13Cr steel. High-concentration PA decreases hydrogen permeation and effectively inhibits SCC. (C) 2012 Elsevier Ltd.
