Abstract:Stress corrosion cracking (SCC) behavior of P110 tubing steel in simulated CO2 injection well annulus environments was investigated through three-pointbent tests, potentiodynamic polarization and EIS measurements. The results demonstrate that SCC of P110 tubing steel could occur in acidulous simulated environment, and the sensitivity of SCC increases with the decrease of pH, as well as increase of sulfide concentration and total environmental pressure. Both anodic dissolution and hydrogen embrittlement make contributions to the SCC.Adequate concentration of corrosion inhibitorcan inhibit the occurrence of SCC on account of the inhibition of localizedanodic dissolutionandcathodichydrogen evolution.

 

Key words: P110 tubing steel; stress corrosion cracking; annulus environment; CO2 flooding
