摘　　要：根据C110抗硫化氢腐蚀套管产品的性能要求,设计开发了Cr-Mo微合金化钢种成分,基于钢种特性实验室研究结果,开展了工业化试验。结果表明,设计产品在经过淬火及高温回火热处理后具有良好的强度及韧性,满足标准对力学性能的要求;而在屈服强度满足标准要求且小于800 MPa时钢管具有良好的抗硫化氢应力腐蚀性能,抗硫化氢检验达到100%通过率难度较大。The components of Cr-Mo microalloyed steel are designed and developed according to the performance requirements of C110 oil casing with resistance to hydrogen sulfide corrosion as well as the industrial tests are carried out based on the research results of characteristics of steel in laboratory. The results showed that the designed product was with good strength and toughness after heat treatment of quenching and high temperature tempering, which could satisfy the requirements of mechanical properties of standard;while when the yield strength satisfied the standard requirement and was less than 800 MPa, the tube was with excellent resistance to hydrogen sulfide stress corrosion and the percent of pass for test of resistance to hydrogen sulfied was more difficult to achieve 100%.
