    摘要: A composition for use in a wellbore activity, the composition comprising a stabilized divalent iodide brine, the stabilized divalent iodide brine comprises a divalent salt system, where the divalent salt system comprises a divalent iodide, an primary iodide stabilizer, the primary iodide stabilizer operable to remove free iodine, prevent the formation of free iodine, and suppress TCT, and an aqueous fluid, where the stabilized divalent iodide brine has a density greater than 11 lb/gal, where the stabilized divalent iodide brines has a TCT of less than or equal to 70 deg F.
