Beschreibung
Zusammenfassung:	FIELD: oil and gas production and corrosion protection. ^ SUBSTANCE: invention relates to protection of oil-field pipelines against internal corrosion and resides in continuously dispensing corrosion inhibitor into oil-field fluid stream, said corrosion inhibitor being preliminarily mixed with oil deposit formation water at ratio (1-2):(2-3) to form solution or emulsion. ^ EFFECT: increased protection effect on lower constituent wall of pipe, reduced inhibitor consumption, and enabled inhibitory protection of pipeline sections disposed in immediate proximity to inhibitor introduction point. ^ 2 cl, 2 tbl, 4 ex
