| titleOfInvention | Solid corrosion and scale inhibitor for oil field |
| abstract | The invention discloses a solid corrosion and scale inhibitor for an oil field, which relates to the technical field of chemical medicine reagents used for the oil field. The solid corrosion and scale inhibitor comprises the following ingredients: 2-phosphonic acid butane 1, 2, 4-tricarboxylic acid PBTCA, polyethyleneglycol, sodium hexametahposphate, span-60 and stearic acid, wherein each ingredient accounts for the mass percent of the sum of all the ingredients as follow: 30 percent to 40 percent of 2-phosphonic acid butane 1, 2, 4-tricarboxylic acid PBTCA, 10 percent to 15 percent of polyethyleneglycol, 10 percent to 15 percent of sodium hexametahposphate, 15 to 25 percent of span-60 and 20 percent to 30 percent of stearic acid. The invention is particularly suitable for well tubes of oil-gas wells with server corrosion and scale conditions, and has good corrosion and scale inhibition effects on underground pipe posts and equipment. |
