A paraffin removal experiment method based on asphaltene in-situ utilization comprises the following steps that 1, paraffin removal equipment is assembled, the bottom of a rotating cylinder with the upper end open and the bottom closed is fixed to the middle of a tray, an outer cavity formed by the rotating cylinder and a cold finger cylinder is filled with paraffin removal liquid containing asphaltene, and then the cold finger cylinder is fixed to the middle of the interior of the rotating cylinder; 2) introducing water into the cold finger cylinder through a cooling water exchanger to form circulation, and controlling the water in the cold finger cylinder to be within a required experimental temperature range; (3) introducing water into the constant-temperature water bath through the constant-temperature water bath instrument to form circulation, and controlling the water in the constant-temperature water bath to be within a required experimental temperature range which is controlled above the melting point
