The disclosure relates to a method for producing heavy oil by generating solvents in situ in the reservoir, an electric heating device is used to heat up the crude oil in the reservoir near the wellbore to the target temperature. Chemical reaction additives are injected into the heating section to meet the preset reaction conditions for the high temperature thermal cracking and aquathermolysis of crude oil, so as to generate light hydrocarbon components and gases. Under the effect of heat and gravity, the light hydrocarbon components and gases rise to the steam chamber. The light hydrocarbons and some gases that move to the vapor-liquid interface of the steam chamber are dissolved in the crude oil to reduce the viscosity of crude oil and increase the production rate of crude oil.
