METHOD OF PRODUCTION AND USAGE OF LONG-TERM ACTIVE REAGENTS FOR PROTECTION OF EXTRACTING OIL WELLS AND ASSOCIATED TECHNOLOGICAL EQUIPMENT FROM CORROSION AND SCALE Russian patent published in 2018 - IPC C09K8/528 C23F11/10 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of inorganic and polymeric chemistry, and more particularly to the protection against scaling and corrosion of producing oil wells. Method for producing and using reagent for protecting an oil well and associated equipment from scaling and corrosion involves loading into the mixer the components of the mixture at the following ratio, mass.%: corrosion inhibitor base 15–40, scale inhibitor base 20–50, acidity regulator 10–20, inhibitors release rate regulator 1–10, specific weight regulator 10–30, solvent – the rest. Resulting mass is formed into cuttings, granules or crumbs, dried from the excess content of volatile compounds and ground, thus obtaining the product form of the reagent for further use.

EFFECT: provides enhanced protection of the oil well and associated equipment from scaling and corrosion during the long life of the well.
