Anti-corrosion and Life Prediction of Artificial Migration Well Casing
摘 要
通过模拟人工运移井封堵完好和封堵泄漏两种腐蚀工况,评价不同添加量下两种缓蚀剂HYF-01和HSJ-JL-01对N80套管钢的缓蚀效果,并计算了N80套管耐腐蚀寿命,筛选出满足套管15 a封堵年限要求的缓蚀剂及最佳添加量。结果表明:封堵完好情况下,HYF-01和HSJ-JL-01两种缓蚀剂的添加量为0.1%(质量分数,下同)时,缓蚀效果相对较好;封堵泄漏情况下,HYF-01和HSJ-JL-01两种缓蚀剂的添加量为1.0%时,缓蚀效果相对较好。经过计算可知:添加0.5%和1.0%的HYF-01均能满足套管15 a封堵年限要求。
Abstract
By stimulating plugging soundness and plugging leakage, the corrosion inhibition of two kinds of inhibitor, HYF-01 and HSJ-JL-01, in different contents was evaluated, and the anti-corrosion life of N80 casing steel was calculated to choose the inhibitor and its best content to meet the requirement of anti-corrosion life of 15 years. The results show that the best content was 0.1% (mass fraction ) for both HYF-01 and HSJ-JL-01 in plugging soundness, and was 1.0% for both HYF-01 and HSJ-JL-01 in plugging leakage. Adding 0.5% and 1.0% HYF-01 could meet the requirement of anti-corrosion life of 15 years.
