采用Brookfield Ultra LVDV －Ⅲ流变仪，研究了在功率0～240 W、时间0～40 min和温度40～70℃的条件下，频率为120 kHz的超声波对大庆原油的降粘效果。结果表明，当时间为30 min、温度为60℃时，原油的降粘率与0～240 W范围内的超声波作用功率存在明显正相关性；在温度45℃、时间30 min和超声波功率240 W的条件下，超声波降低原油粘度的效果最优，降粘率高达46．4％；超声波对温度高于70℃的原油无降粘效果。频率为120 kHz的超声波能否在原油降粘的工业化生产中得到应用仍需进一步探究。

The effects of ultrasonic wave on viscosity reduction of Daqing crude oil under ultrasonic power of 0-240 W ,action time of 0-40 min and action temperature of 40-70 ℃are studied by using Brookfield Ultra LVDV - Ⅲ rheometer and LV1 rotor .The results show that under the conditions of ultrasonic action temperature of 60 ℃ and action time of 30 min ,positive correlation exists between viscosity re-duction of crude oil and ultrasonic power while ultrasonic wave power is 0-240 W;Under the conditions of ultrasonic action temperature of 45 ℃ ,action time of 30 min and ultrasonic power of 240 W ,viscosity reduction effect of ultrasonic wave on crude oil is optimal and viscos-ity reduction rate reaches 46 .4% ;Ultrasonic wave has no viscosity reduction effect on crude oil over 70 ℃ .Whether industrial application of 120 kHz ultrasonic treatment to viscosity reduction of crude oil is feasible or not is yet to be further explored .
