Beschreibung
Zusammenfassung:	FIELD: oil and gas production and corrosion protection. ^ SUBSTANCE: invention relates to protection of oil-field equipment and pipelines operated under conditions when oil formations are microbiologically infected. In particular, when oxygen-containing fresh water with demulsifier is continuously supplied to waste water disposal system, the latter is subjected to a single treatment with bactericidal reagent acidified with weak hydrochloric acid solution containing corrosion inhibitor, after which oxygen dissolved in fresh water is completely removed. ^ EFFECT: prohibited favorable conditions in waste water disposal system for vital activity of bacteria and prevented corrosion of equipment. ^ 1 dwg
