【摘要】：随着酸性油气田的陆续出现,钻杆在酸性环境下腐蚀性能的研究显得尤为重要。采用金相显微镜、万能试验机、冲击试验机、扫描电镜、能谱仪等对不同热处理后V150钻杆材料的性能进行了研究。结果表明:热处理可以提高V150钻杆材料的抗硫化氢应力腐蚀(SSC)性能及氢致开裂(HIC)性能;二次回火对V150钻杆材料的力学性能及腐蚀性能影响不大。夹杂和缺陷是导致V150钻杆材料抗SSC性能降低的主要原因。HIC试验后试样的主要腐蚀产物为Fe和Mn的硫化物,Cu,Ni等元素有利于提高G105钻杆材料的抗HIC敏感性。
[Abstract]:With the emergence of acid oil and gas fields, it is very important to study the corrosion performance of drill pipes in acid environment. Metallographic microscope, universal testing machine, impact testing machine, scanning electron microscope are used. The properties of V150 drill pipe materials after different heat treatment were studied by energy spectrometer. The results show that heat treatment can improve the properties of hydrogen sulfide stress corrosion resistance and hydrogen induced cracking (HICs) of V150 drill pipe materials. The secondary tempering has little effect on the mechanical properties and corrosion properties of the V150 drill pipe material. Inclusions and defects are the main reasons for the decrease of the SSC resistance of the V150 drill pipe materials. The main corrosion products of the specimens after HIC test are Fe and mn sulfides. The HIC sensitivity of G105 drill pipe material is improved by elements such as Cu-Ni and so on.
