Corrosion and scaling rate prediction method considering multi-factor coupling effect

The invention discloses a corrosion and scaling rate prediction method considering a multi-factor coupling effect, and belongs to the technical field of oil and gas field corrosion protection. The method is characterized by comprising the following steps: firstly, carrying out correlation analysis on collected work area corrosion and scaling parameters and determining main control factors; simulating a metal corrosion and scaling experiment through orthogonal design, and obtaining a corrosion and scaling rate regression equation in combination with a multiple regression analysis method; and finally, checking the regression equation and the regression coefficient, so that the prediction precision can be improved by reducing the horizontal interval of the main control factors and increasing the experiment expansion sample. According to the experiment of the influence of the main control factors on the corrosion and scaling rate, the corrosion and scaling rate under a larger range of working conditions can be pr
