MATERIALS EVALUATION IN C02 CORROSION ENVIRONMENT
油田CO2腐蚀环境中的选材评价

J55,N80 and PllO was evaluated in the same CQmion amdition. It was found that the corrosion rates of the three kinds of materials follmied the order: PllO >N80 >J55. Serious local cornion appeared on the sample surfaces of N80 and PllO at 70C. 90°C and 110°C .When CQpartial pressure was 25.3 x 10' Pa at 90°C , cornion rates reached the maximum.
