Abstract: The corrosion inhibitor blend of at least one corrosion inhibitor base (which may be a Mannich reaction product), a solvent selected from the group consisting of C 1 acids and ester and salt derivatives thereof, and optionally a surfactant, has been found to be effective as a corrosion inhibitor for metals in acid media, particularly fluids containing halogen acids. The corrosion inhibitor has improved performance over similar or identical corrosion inhibitor compositions where an alcohol such as methanol is used as a solvent. Suitable, nonlimiting possibilities for the solvent include, but are not necessarily limited to formic acid, format salts, methyl format, ethyl format, benzyl format, format salts of amines, inorganic format, and mixtures thereof.

Abstract: It has been discovered that carbonate powders and bicarbonate powders are useful to increase the pH and corrosion resistance of high- density brines, such as zinc bromide brines, without significantly reducing their densities. The carbonates and/or bicarbonates should be water-soluble and may be sodium, potassium, magnesium and/or ammonium carbonates and/or bicarbonates and the like. The carbonates and/or bicarbonates are easily added in powder or other finely divided solid form and are completely dissolved in the brine prior to pumping the brine into a subterranean formation.
Abstract translation: 已经发现碳酸盐粉末和碳酸氢盐粉末可用于提高高密度盐水如溴化锌盐水的pH和耐腐蚀性，而不显着降低它们的密度。 碳酸盐和/或碳酸氢盐应该是水溶性的并且可以是碳酸钠，碳酸钾，碳酸镁和/或碳酸铵和/或碳酸氢铵等。 碳酸盐和/或碳酸氢盐很容易以粉末或其他细碎的固体形式加入，并在将盐水泵入地层之前完全溶解在盐水中。
