petroleum-extracting industry, more particularly petroleum and gas industries. SUBSTANCE: composition comprises, wt %: oxyethylidene diphosphonic acid, 4-15; monoethanol-amine, 5-15; nitrilotrimethyl phosphonic acid, 15-25; hydroxy-containing compound, 25-30; and water, the balance. Invention makes it possible to attain high efficiency of prevention of calcium deposits at high coefficients of superrsaturation of mineralized water and retention of low solidification temperatures. EFFECT: improved properties of the composition. 1 tbl
