The disclosure provides a method and apparatus for predicting an optimal exploitation approach for shale oil in-situ conversion. The method includes: determining a lower limit temperature required for completely converting convertible organic matter in a shale to be measured into oil and gas, based on a pre-established relationship between the temperature rise rate and the lower limit temperature; determining an optimal well distance of heating wells, based on a thermal field parameter of a target reservoir of interest, an optimal heating time corresponding to the lower limit temperature, and a pre-established relationship between an optimal well distance of heating wells and the optimal heating time; determining an oil yield equivalent based on a temperature and an oil yield equivalent of the shale; determining an optimal well pattern; the lower limit temperature, the optimal well distance of heating wells, the oil yield equivalent and the optimal well pattern are optimal parameters.
