2) After being over-pressurized, steam entering the cleaning pipe pump enters a steam jet pipe of the oil well oil pipe cleaner through the flexible cleaning pipe, and high-temperature steam washing is carried out on the oil well oil pipe in the lifting process;
3) After the high-temperature steam is contacted with the oil pipe of the oil well, crude oil dirt on the outer wall of the oil pipe of the oil well is washed and condensed into liquid water, and the condensed liquid water and the crude oil dirt flow to a recovery tank through a water drainage short connecting pipe water outlet between the outer wall of the oil pipe of the oil well and an oil pipe sleeve of the oil well; the controller monitors a temperature signal in the combustor, a liquid level signal in the water supply tank, a winding and unwinding speed signal of the flexible cleaning pipe on the winding machine and a liquid level signal of the recovery tank in real time, and compares the received temperature signal in the combustor, the received liquid level signal in the water supply tank, the received winding and unwinding speed signal of the flexible cleaning pipe on the winding machine and the received liquid level signal of the recovery tank after being converted by the data conversion module with a preset temperature threshold value in the combustor, a preset liquid level threshold value in the water supply tank, a preset winding and unwinding speed threshold value on the winding machine and a preset liquid level threshold value in the recovery tank respectively; and controlling the regulating quantities of the corresponding first water quantity regulating valve, the second water quantity regulating valve, the winder speed regulating valve and the electromagnetic air supply valve according to the comparison result.
