Corrosion activity of produced water from flooded wells in “Neft Dashlary” OGPD has been researched. As a major index in the analysis corrosion rate, the presence of bacteria reducing sulphate, the amount of hydrogen sulfide, as well as the quantity of sulphates and chloride ions have been considered. It was revealed that the amount of bacteria reducing sulphates in 104 wells changes within 103–108 kl/ml, hydrogene-sulfide concentration in 60 wells is between 50–119.0 mg/l, corrosion rate of metal in produced water of 154 wells comprises 0.6–2.4 mm/year, and in 14 wells - 2.5145–3.8749 mm/year. Based on carried out research works on corrosion protection of field equipment in “Neft Dashlary” OGPD, the use of inhibitors of complex activity and agents with bactericide properties is recommended against general and microbiological corrosion.
