CORROSION OF ADVANCED STEELS:CHALLENGES IN THE OIL AND GAS INDUSTRY
Drill pipe steels are in contact with CO2 and H2S environments,depending on the oil and gas field.These steels have to be resistant to various in-service conditions including aggressive environments containing CO2,H2S,O2,and chlorides,in addition to static and dynamic mechanical stresses.In this respect stress corrosion cracking susceptibility of two grades of drill pipe steel in CO2 environment have been studied simulating the bottom hole oil and gas well conditions.SSRT results show that SCC susceptibility or loss of ductility changes with temperature and increasing temperature increases the loss of ductility.No FeCO3 is observed below 100 ℃,and density of FeCO3 is higher in grip section than gauge length and this is due to strain disturbance of growth of iron carbonate crystals.Material selection for down hole in CO2 containing environments needs has been reviewed and probability of SCC occurrence in higher temperatures has been included.
