    摘要:

    本文利用空化射流技术开展了稠油降粘的实验研究。根据实验条件自行设计和制造了空化射流稠油降粘实验系统,并利用该实验系统研究了两种空化喷嘴及空化射流处理次数等参数对稠油降粘效果的影响,分析了稠油在空化射流处理前后粘度发生的变化。实验研究结果表明:两种空化喷嘴对稠油的降粘都有一定的作用,稠油粘度随着空化射流处理次数的增加逐渐降低。通过角形空化喷嘴和风琴管空化喷嘴处理后,稠油粘度最大降低52mpa?s和88mpa?s,降粘率分别为13.33%和18.49%。实验验证了空化射流技术可以一定程度的改变稠油的性质,实现稠油的降粘,改善稠油的品质,在合理运用下可以成为一种稠油降粘的新方法。

    Abstract:

    The experimental study of heavy oil viscosity reduction was carried out by using cavitation jet technology in the paper. An experimental system for viscosity reduction of heavy oil with cavitation jet was designed and manufacture. The effect of two kinds of cavitation nozzle and cavitation jet treatment numbers on the heavy oil viscosity reduction was studied through the self-designed experimental system and the changes of heavy oil viscosity before and after cavitation jet treatment was analyzed. The experimental results show that two kinds of cavitation nozzle have a certain effect on the viscosity reduction of heavy oil and the viscosity of heavy oil decreases with the increase of cavitation jet treatment numbers. After the treatment of cavitation jet generated by angle cavitation nozzle and organ pipe cavitation jet, the viscosities of heavy oil maximally reduce 52 mpa?s and 88 mpa?s respectively, and the rates of viscosity reduction are 13.33% and 18.94% respectively. The experiment verifies that the cavitation jet technology can change the nature of heavy oil, reduce the viscosity of heavy oil, and improve the quality of heavy oil. It can became a new method of viscosity reduction of heavy oil in reasonable use.
