摘　　要：采用扫描电子显微镜(SEM)、X射线能谱分析仪(EDS)、数显维氏硬度计、3D光学数码显微镜、直读光谱仪(OES)等高精设备,对油田生产水系统斜板除油器水出口管线进行了失效分析,着重分析了基材成分、力学性能、表面硬度、腐蚀产物等内容。结果表明,管线腐蚀主要来自H2S和CO_(2)的腐蚀,其中H2S对腐蚀有显著作用。Using scanning electron microscope(SEM),X-ray spectroscopy analyzer(EDS),digital Vickers hardness tester,3D optical digital microscope,direct reading spectrometer(OES)and other high-precision apparatuses,the failure analysis of the water outlet pipeline of the inclined plate oil-remover of the oilfield production water system is carried out.In particular the substrate composition,mechanical properties,surface hardness and corrosion products,etc.are analyzed.The results show that the corrosion mainly caused by H_(2)S and CO_(2).Furthermore,H_(2)S has a significant effect on corrosion.
