Intelligent nano single-phase fluid for removing and inhibiting composite scale and preparation method thereof

The invention discloses an intelligent nano single-phase fluid for removing and inhibiting composite scale and a preparation method of the intelligent nano single-phase fluid. The intelligent nano single-phase fluid is prepared from the following components in percentage by weight: 16 to 36 weight percent of organic solvent, 3 to 11 weight percent of acid, 16 to 36 weight percent of surfactant, 16 to 36 weight percent of cosurfactant, 100 to 1000 ppm of wax inhibitor, 400 to 1200 ppm of asphalt inhibitor, 0.01 to 0.08 weight percent of inorganic scale inhibitor and the balance of water. The system provided by the invention has a certain inhibition effect on organic scales (such as wax and asphaltene) and inorganic scales, can effectively prevent formation of wax crystals, asphaltene and inorganic scales, and prevents accumulation of the wax crystals, asphaltene and inorganic scales, so that the descaling period is prolonged; and the cleaning agent also has a good cleaning effect on organic scales such as wax,
