Head Khoma Myroslav S., Доктор технічних наук Registration Date 14-12-2021 Organization Physico-Mechanical Institute named after GV Karpenko of the National Academy of Sciences of Ukraine popup.description1 To establish regularities of influence of concentration of carbon dioxide and hydrogen sulfide in formation waters on corrosion-mechanical destruction of pipe steels (P-110, Q-125 and V-150) in relation to their corrosion rate and flooding. popup.description2  Regularities of hydrogenation and corrosion-mechanical destruction of low-alloyed tubular steels of strength groups P110, Q125 and V150 in the environment of highly mineralized model formation waters (MFW) containing CO2 and H2S have been established. It is shown that in MFW + CO2 the corrosion rate of steels increases with time, which indicates the absence of a protective effect of carbonate films. In MFW + СО2 + Н2S the corrosion rate of steels decreases due to the formation the surface films consisting of a mixture of maquinavit, troilite and impurities of oxides and hydroxides of iron. In MFW + CO2 + H2S, the strength of steels increases by 13… 30%, and ductility decreases by 5… 11 times, which is associated with hydrogenation and cracking.
