Recognising the advantages of the cavitation jet, we propose the utilisation of a rotating self-propelled cavitation jet for tube cleaning. In this study, we conducted a performance experiment involving an organ pipe cavitation nozzle and subsequently carried out tube cleaning experiments using the cavitation nozzle. These experiments explored varying standoff distances and injection angles to determine the most suitable parameters for effective cleaning. Furthermore, we designed the structure of the rotating self-propelled cavitation nozzle and involved tube-scale cleaning experiments to ascertain the impact of pressure and feed speed on the mineral scale cleaning rate achieved by the rotating self-propelled cavitation nozzle. To validate the cleaning performance of the rotating self-propelled nozzle in real-world well-site conditions, we conducted additional cleaning experiments on-site. The findings of this study offer crucial technical support for the efficient and cost-effective cleaning of mineral scale deposits within tubes.
