Abstract — The corrosion behavior of steel in a hydrogen-sulfide medium is studied in model solutions simulating stratal water in some oil fields located in Perm’ oblast. A comparative analysis of the corrosion inhibitors used in the oil fields is presented. Some inhibitors are found to have a significant residual effect.
