  When used outside the pH range at which metal ion complexation normally occurs, aminopolycarboxylic acids can moderate the reaction rate of acids with carbonate minerals. Methods for treating a subterranean formation can comprise: providing a treatment fluid comprising an aqueous carrier fluid, an acid, and a chelating agent comprising an aminopolycarboxylic acid, the treatment fluid having a pH below that at which the carboxylic acid groups of the chelating agent are substantially protonated and the chelating agent is ineffective for complexing a metal ion; introducing the treatment fluid into a subterranean formation comprising a carbonate mineral; reacting the acid with the carbonate mineral, such that the acid at least partially spends and the pH of the treatment fluid rises; and once the pH of the treatment fluid rises above a pKa value for one or more of the carboxylic acid groups, complexing a metal ion with the chelating agent.

  在金属离子通常发生络合反应的 pH 值范围之外使用时，氨基多羧酸可减缓酸与碳酸盐矿物的反应速度。处理地下岩层的方法可包括提供一种由含水载液、酸和由氨基多羧酸组成的螯合剂组成的处理液，处理液的 pH 值低于螯合剂的羧酸基团基本质子化且螯合剂不能有效络合金属离子的 pH 值；将处理液引入包含碳酸盐矿物的地下岩层；使酸与碳酸盐矿物反应，从而使酸至少部分消耗，处理液的 pH 值升高；一旦处理液的 pH 值升高到一个或多个羧酸基团的 pKa 值以上，金属离子就会与螯合剂络合。
