[0002] Oil wells have the characteristic of containing wax. As the pressure of direct injection oil wells decreases or the temperature of the wellbore decreases, wax will precipitate and adhere to the wellbore, causing wellbore blockage and affecting the normal production of the oil well. Wax cleaning operations are required. Existing mechanical wax cleaning operations require the establishment of an operating platform at the wellhead, and operators operate the wellhead equipment and wax cleaning equipment on the operating platform.

[0003] However, due to the different pressures at each wellhead, the height of the blowout preventer and the weight of equipment such as the weighted rod for the wax cleaning operation need to be adapted to the wellhead pressure. The higher the wellhead pressure, the higher the corresponding blowout preventer height needs to be, the heavier the weighted rod needs to be, and the corresponding operating platform needs to be set higher.
