摘要（英）：

The invention discloses a decarburization solution for recovering and removing carbon dioxide gas from the carbon dioxide flooding produced gas of an oilfield, comprising a main absorbing component, an activating component, a corrosion inhibitor, an antioxidant, a defoamer and water, wherein the main absorbing component is K2CO3 or MDEA (methyldiethanolamine); an auxiliary absorbing component is DIPA (diisopropanolamine) or MEA (mono edawnol amine) or MMEA (methyl monoethanolamine) or AEEA (aminoethylethanolamine) or DMEA (dimethylethanolamine); the activating component is DEA (diethanol amine) or PZ (zinc dimethyldithiocarbamate) or AEP (polyoxyethylene potassium dodecyl phosphate) or TETA (triethylene tetramine) or DETA (diethylenetriamine) or TEPA (tetraethylenepentamine) or glycine; the corrosion inhibitor is V2O5; the antioxidant is sodium metavanadate or potassium tartrate; the defoamer is dimethyl silicon oil or hexanol or heptanol or octanol; and the ratio of the main absorbing component to the auxiliary absorbing component to the activating component to the corrosion inhibitor to the antioxidant to the defoamer is (0.2 to 0.3): (0.03 to 0.05): (0.01 to 0.03): (0.005 to 0.008): (0.005 to 0.008): (0.0005 to 0.001).
