摘　　要：利用高温高压釜模拟油田环境下09Cr2AlMoRE钢的CO2腐蚀行为,计算其平均腐蚀速率并对腐蚀产物进行分析。发现09Cr2AlMoRE在CO2腐蚀环境中主要是均匀腐蚀,平均腐蚀速率较大;其腐蚀产物膜主要成分为FeCO3,但不同温度下其成分又各有不同。试验结果表明,该材料在CO2腐蚀环境中不具有优越性,使用时应充分考虑其使用环境。The corrosion of 09Cr2AlMoRE steel in CO2 environments was studied by autoclave. It was calculated its average corrosion rate and analyzed the composition of its corrosion products. It is mainly uniform corrosion, and its corrosion rate is bigger; the ingredient of its corrosion product scale is mainly FeCO3, but it is different in various temperatures. The result shows that 09Cr2AlMoRE is not very good for CO2 environments, so it is necessary to considerate the using environment for this kind of steel.
