Self-heat-generation scale removing and inhibiting agent aiming at composite scale and preparation method of self-heat-generation scale removing and inhibiting agent

The invention provides a self-heat-generation scale removal and inhibition agent aiming at composite scale and a preparation method thereof, the self-heat-generation scale removal and inhibition agent comprises an emulsion A and a solution B, and the mass ratio of the emulsion A to the solution B is 1: (3-5); the emulsion A is prepared from the following components in percentage by mass: 1 to 2 percent of polyester-based oil phase, 0.2 to 0.5 percent of anionic surfactant and 97.5 to 98.8 percent of water; and the solution B comprises the following components in percentage by mass: 98-99% of a solvent and 1-2% of phosphorus halide. High-reaction-activity substances are transferred into blockages by means of carriers such as the reactive-hydrogen-free organic solvent and the surfactant, exothermic reaction of the high-reaction-activity substances and water or organic matter is facilitated, the viscosity of organic scale can be effectively reduced through heat released by the reaction, acid, ester and polycarbo
