When drilling oil and gas well with high pressure, to protect the hydrocarbon reservoir and decrease the damage to stratum, bromide( CaBr2,ZnBr2 )needs to be used, which density is 2.30g/cm3..These strong solution of saline has strong causticity, and the causticity will increase with rising of temperature. In some high pressure wells, the temperature could reach 200°C. Through experiments, it is proved that as the inhibitor, only sulfur compound can restrain brine corrosion under high temperature of 140-200°C. It is because that these compounds will act with metal under a certain temperature, and will form a compact FES protective film. Ammonium Thioglycolate is an excellent inhibitor that can be used as wnickel salt well completion liquid , when used separately, it has an good effect under a temperature scope between149°C-204°C. Normally, It should be used together with thiocyanate inhibitor and antioxidant (saccharides and aldehydes).The formula of inhibitor is to add Ammonium 0.6% of Thioglycolate, 0.4% of sodium thiocyanate, and 0.8% ascorbic acid 0.8%. Add these material according with the formula to well completion liquid, which is with the density of 2.0g/cm3 and with ZnBr2 included. After seven days corrosion test, the corrosion speed is 0.155mm/a.
