摘要
对在某油田使用的三种材料J55、N80、P1 1 0进行评价和筛选 .三种材料平均腐蚀速率为P1 1 0 >N80 >J55.其中 ,N80和P1 1 0试样表面出现了严重的局部腐蚀 .
J55、N80 and P110 was evaluated in the same CO 2 corrosion condition. It was found that the corrosion rates of the three kinds of materials followed the order: P110>N80>J55. Serious local corrosion appeared on the sample surfaces of N80 and P110 at 70℃、90℃ and 110℃.When CO 2 partial pressure was 25.3×10 5 Pa at 90℃, corrosion rates reached the maximum.
