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.
