摘　　要：采用氧腐蚀试验、CO2腐蚀试验、硫化物应力腐蚀试验,对比分析36Cr Ni Mo4与4130H两种材质钻杆的抗腐蚀性能。分析结果表明:36Cr Ni Mo4与4130H两种材质钻杆的氧腐蚀速率基本相同;36Cr Ni Mo4材质钻杆的抗CO2腐蚀性能优于4130H材质,但抗硫化物应力腐蚀开裂性能明显低于4130H材质。Comparative analysis of the anti-corrosion behaviors of the drill pipes made of the 36CrNiMo4 and the 4130H steels are conducted by means of oxygen corrosion test, CO2 corrosion test and SSC test. The test results shows that the oxygen corrosion rates of the 36CrNiMo4 pipe and the 4130H pipe are basically the same, and that the CO2 corrosion resistance of the 36CrNiMo4 pipe is better than that of the 4130H pipe, whereas the SSC resistance of the former is remarkably less than that of the later.
