FIELD: corrosion protection.
SUBSTANCE: invention relates to means protecting oil-field equipment against hydrogen sulfide corrosion, in particular to reagents suppressing growth of sulfate-reducing bacteria. Proposed bactericide is product obtained by reaction of primary aliphatic C8-C18-amines with phosphorus-containing acid derivative, the latter, in particular, being by reaction of phosphorous acid and polyatomic alcohol at their molar ratio 1:(0.8-1.2), respectively.
EFFECT: enhanced protective and bactericidal properties.
