Petroleum thermal recovery device

The petroleum thermal recovery device comprises a box body, a pump shell and a snakelike oil pipe, the snakelike oil pipe is installed in the box body through an installation frame, a heat conduction pad is filled between the snakelike oil pipe and the box body, electric heating wires are embedded in the heat conduction pad at equal intervals, the feeding end of the snakelike oil pipe is connected with the pump shell through a flange, and the pump shell is connected with the pump shell through a flange. A driving motor is mounted at the top of the pump shell through a mounting frame, a shaft rod is mounted in the pump shell through a bearing, and material pushing plates used for pushing materials are fixed to the outer side of the shaft rod at equal intervals through bolts. The heat conduction pad made of the graphene material is used for directly conducting the temperature generated after heating of the multiple electric heating wires to the snakelike oil pipe, oil in the snakelike oil pipe is heated, heat i
