PROPERTIES OF A HIGHLY EFFICIENT COMPOUNND CORROSION INHIBITOR IN OFFSHORE OILFIELD

Corrosion inhibitor HYH-4251 has been investigated by using dynamic high pressure coupon testing,polarization curve measurement,compatibility test with incumbent scale inhibitor and demulsifier,third party evaluation and on-site application.All results have demonstrated that this corrosion inhibitor is a mixed type of absorptive inhibitor and can effectively inhibit localized corrosion with characteristics of low emulsification and good compatibility.
