The control of corrosion in the oilfield is a complex problem, requiring detailed analysisand a thorough understanding of the range of conditions expected during the life of thesystem prior to the development of a corrosion management plan. DESHI Chemical hasdeveloped of a number of corrosion inhibitor formulations to solve the corrosion problemsin different phases of oil production. Applications include controlling corrosion in all typesof oilfield operations, including oil and gas production, processing, and transportationsystems.
The use of highly acidic stimulation fluids can lead to severe metal corrosion and
hydrogen and chloride stress cracking. Corrosion inhibitors for protection of carbon and
chrome steels during acidizing are mostly different from those used to treat production
fluids and usually dosed at higher concentrations.
The product is used in oil and gas well acidizing fluid as corrosion inhibitors, protecting

 

equipment and pipelines. It has good thermo stability under temperature 60 ~ 180 °C
