as the main raw material of cold blanching;
When drilling high-pressure oil and gas wells in oil exploration, in order to protect the oil and gas layer and reduce the damage to the formation, it is necessary to use solid-phase completion fluid without bromide (CaBr2, ZnBr2, etc.), which can reach a density of 2.30g/cm3. The concentrated solution of these salts is highly corrosive, and its corrosiveness intensifies with the increase of temperature, and the temperature of some high-temperature wells reaches 200°C. Tests have proved that the only corrosion inhibitors that can inhibit saltwater corrosion at a high temperature of 140-200°C are sulfur-containing compounds. This is due to the chemical reaction of these compounds with metals at a certain temperature to form a dense protective film of FeS. Sulfhydryl acetate is an excellent corrosion inhibitor for bromine salt completion fluids. When used alone, it works well in the temperature range of 149°C-204°C, but is often used in combination with thiocyanate corrosion inhibitors and antioxidants (aldehydes/sugars). The formulation of its corrosion inhibitor is: ammonium mercaptoacetate 0.6%, sodium thiocyanate 0.4%, sodium erythorbate 0.8%. According to the above corrosion inhibitor dosage, the corrosion rate of the steel sheet is only 0.155mm/a after 7 days of corrosion test when added to the completion fluid containing ZnBr2 with a density of 2.0g/cm3.
