摘　　要：采用原油超声处理试验装置,分析了超声作用时间、作用温度、超声频率、超声功率、原油黏度变化对降黏效果的影响。结果表明,当温度低于70℃时,超声处理促使原油黏度显著降低,温度高于70℃时,原油经过超声处理后黏度反而增加,主要是空化阈值的影响结果。随着超声作用时间的变大,原油超声处理后降黏率先升高后降低,主要与超声热作用相关。超声功率变大后,达到相同的超声空化效果所需要的时间变短,最优超声作用时间变短。随着超声功率的增大,超声降黏率先升高后降低,存在临界最优超声功率。超声处理降黏对于50℃、黏度为500~1081 mPa·s的原油降黏效果较好。Using the crude oil ultrasonic treatment experimental device,the effects of ultrasonic action time,action temperature,ultrasonic frequency,ultrasonic power,and crude oil viscosity changes on the viscosity reduction characteristics are analyzed.The results show that when the temperature is lower than 70℃,the viscosity of crude oil is significantly reduced by ultrasonic treatment.When the temperature is higher than 70℃,the viscosity of crude oil after ultrasonic treatment increases,mainly due to the effect of the cavitation threshold.With the increase of ultrasonic action time,the viscosity reduction of crude oil after ultrasonic treatment increases first and then decreases,which is mainly related to the thermal effect of ultrasound.When the ultrasonic power increases,the time required to achieve the same ultrasonic cavitation effect becomes shorter,and the optimal ultrasonic action time becomes shorter.With the increase of ultrasonic power,ultrasonic viscosity reduction first increases and then decreases,and there is a critical optimal ultrasonic power.The viscosity reduction effect of ultrasonic treatment is better for crude oil with viscosity ranging from 500 mPa·s to 1081 mPa·s at 50℃.
