%X 用金相显微镜、扫描电镜、X射线衍射仪和X射线能谱仪对天然气井油管悬挂器腐蚀失效进行了检测分析，并对天然气井油管悬挂器用35CrMo钢进行了盐雾试验，结果表明，天然气中的水和CO2是引起腐蚀的主要介质，腐蚀产物主要是FeCO3，高速天然气冲刷和钢中的非金属夹杂加剧了腐蚀的速度.CORROSIONFAILUREANALYSISOFANOILTUBEUSEDINNATURALGASWELLLIUShou-ping,ZHOUShang-qi,WANGJia-mei,RENQinChongqingUniversityAfailedoiltubeusedinnaturalgaswellwasexaminedbyopticalmicroscope,scanningelectronmicroscope,X-raydiffractometerandX-rayspectrometer.Corrosionbehaviorof35CrMosteelsamplesoftheoiltubewereinvestigatedbymeansofsaltspraytestsinthelaboratory.TheresultsshowthatCO2andH2Oareprimaryfactorsinthecorrosionofoiltube.ThecorrosionproductisFeCO3,non-metallicinclusionsinthesteelanderosionofnaturalgasfluidplayedanimportantroleinacceleratingthecorrosion.oiltube;naturalgaswell；35CrMosteel；failureanalysis；corrosion
