FIELD: corrosion protection. SUBSTANCE: invention relates to oil-field equipment operated in hydrogen sulfide-containing media and may be applied in oil production, oil treatment, and oil transportation areas. Inhibitor contains fatty acid-amine interaction product, nonionic surfactant, and solvent. In particular, utilized is product of interaction of 1 wt.pt of tall oil or oleic acid with 0.1-0.5 wt.pts of mono- or diethanolamine, or ethylenediamine; or 8-55 wt.pts of morpholine or morpholine production vat residue. This product is combined with 6-10 wt.pts of surfactant and with solvent. EFFECT: increased protective effect. 2 tbl, 33 exr
