[0002] The main component of crude oil extracted from oil wells is hydrocarbons, which contain paraffin to varying degrees and quantities. During the oil well opening and production process, the temperature becomes lower as the oil well goes up. Temperature is one of the important factors affecting the wax formation in oil wells. When the temperature of the crude oil is lower than the wax precipitation point of the crude oil, the wax originally dissolved in the crude oil will precipitate and mainly condense on the inner wall of the oil well.

[0003] After the oil pipe is taken out, it needs to be cleaned. Traditional cleaning devices usually connect high-pressure hot water to one end of the oil pipe. The high-pressure hot water melts the oil wax and flushes it away, thereby completing the cleaning of the oil pipe.
