The invention relates to the field of oil field water treatment, in particular to compounded oil field corrosion inhibitor and a preparation method thereof. The compounded oil field corrosion inhibitor comprises liquid A and liquid B, wherein the volume ratio of the liquid A to the liquid B is 1: 3; the liquid A comprises, by weight percent, 5%-15% of aromatic ketone mannich base, 3%-10% of fattyalcohol-polyoxyethylene ether, 0.5%-3% of fatty alcohol-polyoxyethylene ether phosphate, 5%-15% of ethyl alcohol, 2%-10% of propargyl alcohol, 15%-35% of hydrochloric acid, 3%-10% of potassium iodideand the balance water; and the liquid B comprises, by weight percent, 5%-15% of oleic acid imidazoline, 5%-10% of fatty alcohol-polyoxyethylene ether, 2%-7% of fatty alcohol-polyoxyethylene ether phosphate, 4%-13% of ethyl alcohol, 2%-8% of formic acid and the balance water. The compounded oil field corrosion inhibitor is suitable for working conditions of an underground oil and water pipeline andeasy and convenient to use and is conveniently applied and popularized on a large scale.
