摘　　要：文章介绍了测井作业中硫化氢气体的来源、腐蚀机理,分析了氢鼓包和应力腐蚀的危害以及螺钉断裂的原因。为避免测井仪器螺钉被硫化氢腐蚀,提高其耐硫化氢腐蚀性能,根据腐蚀机理,从化学成分和金相组织2个方面进行考量,将螺钉材质由原来的0Cr18Ni9更换为MP35N。This paper introduces the source and corrosion mechanism of hydrogen sulfide gas in logging operation,analyzes the harm of hydrogen bulge and stress corrosion,and causes of screw breakage.In order to avoid being corroded by hydrogen sulfide and improve its resistance to hydrogen sulfide corrosion,the material of the screw is changed from 0Cr18Ni9 to MP35N according to the corrosion mechanism and from two aspects of chemical composition and metallographic structure.
