Abstract: Petroleum has always been a strategic resource for our country, and wax deposition in oil wells has been a key problem plaguing the oil extraction industry. This paper takes the wax removal and prevention technology for pumping unit wells as the research object, aiming to solve the problem of decreased production efficiency and increased economic losses caused by wax deposition in pumping unit wells. Firstly, the hazards and mechanism of wax deposition in oil wells were summarized, highlighting the significance of wax removal and prevention work. Subsequently, the methods for judging wax deposition in oil wells were sorted out, and a deeper understanding of wax deposition in the field was achieved. It focuses on elaborating various wax removal and prevention methods such as mechanical wax removal, hot washing wax removal, chemical wax removal, electromagnetic wax prevention, and microbial wax prevention and so on. Through comparing and analyzing the principles, advantages and disadvantages, combined with application cases, it discusses the characteristics of different wax removal and prevention technologies. Finally, it is pointed out that the future development trend of wax removal and prevention in pumping wells will be more inclined towards intelligence, greenness and collaboration, providing technical support for the efficient, stable and green production of pumping wells.
