The invention provides a paraffin removal system, which comprises a paraffin removal tool, a connecting piece and a lifting tool. The lifting tool comprises a supporting device, a pulley and one or more fixing devices; the first end of the supporting device is connected with the one or more fixing devices, and the second end of the supporting device is fixedly connected with the pulley; the fixingdevices are used for fixing the lifting tool to a blowout prevention pipe; and the connecting piece is connected to the pulley in a hung mode, the first end of the connecting piece is connected withthe paraffin removal tool, and the second end of the connecting piece is used for controlling ascending and descending of the paraffin removal tool to enable the paraffin removal tool to enter the blowout prevention pipe. According to the paraffin removal system, compared with the prior art, the labor intensity of a worker is reduced, the falling risk of the worker is further lowered, the worker does not need to stand on the position above a pipe orifice of the blowout prevention pipe, thus contact with poisonous gas emitted by the blowout prevention pipe is avoided, and the poisoning risk islowered.
