Whendrilling oil and gas well with high pressure, to protect thehydrocarbon reservoir and decrease the damage to stratum, bromide( CaBr₂,ZnBr_{2 )}needs to be used, which density is 2.30g/cm^3..Thesestrong solution of saline has strong causticity, and the causticitywill increase with rising of temperature. In some high pressure wells,the temperature could reach 200°C. Throughexperiments, it is provedthat as the inhibitor, only sulfur compound can restrain brine corrosionunder high temperature of 140-200°C. It is because that thesecompoundswill act with metal under a certain temperature, and willform acompact FES protective film. Ammonium Thioglycolate is anexcellentinhibitor that can be used as wnickel salt well completionliquid , whenused separately, it has an good effect under atemperature scopebetween149°C-204°C. Normally, It should be usedtogether withthiocyanate inhibitor and antioxidant (saccharides andaldehydes).Theformula of inhibitor is to add Ammonium 0.6% ofThioglycolate, 0.4% ofsodium thiocyanate, and 0.8% ascorbic acid 0.8%.Add these materialaccording with the formula to well completionliquid, which is with thedensity of 2.0g/cm³ and with ZnBr₂ included. After seven days corrosion test, the corrosion speed is 0.155mm/a.
