ВЫСОКОТЕМПЕРАТУРНЫЕ ИНГИБИТОРЫ КОРРОЗИИ ДЛЯ СОЛЯНОКИСЛОТНОЙ ОБРАБОТКИ СКВАЖИН

Abstract

In order to obtain high-temperature corrosion inhibitors, compositions were prepared based on “Sumono-extra”, a condensation product of the croton fraction with ammonia in methanol and methenamine, thiourea with copper salts. The inhibitory properties of the inhibitor during steel corrosion in hydrogen sulfide-carbon dioxide environments of various compositions were studied using gravimetric testing. the influence of temperature on the corrosion rate and the protective effect of the inhibitor.
