摘　　要： 采用Brookfield DV-ⅢUltra流变仪、LV1转子、10 r/min测量转速,研究了在功率为0-240 W、作用时间为0-40 min、温度为30-80℃的条件下,120 kHz的超声波对中国石化茂名分公司加工所使用的酸值为1.82 mg KOH/g的高酸原油的降粘效果。结果表明,经240 W、30 min和50℃的优化条件处理后,高酸原油的粘度从59.3 mPa·s降低至39.4 mPa·s,降粘率为26.9%。超声波处理后的高酸原油经50℃恒温静置24 h,其表观粘度基本恢复。 The effects of ultrasonic wave on viscosity reduction of high total acid number crude oil of 1.82 mgKOH/g takeing from Sinopec Maoming company under ultrasonic power of 0 - 240 W, action time of 0 - 40 min and aeiton temperature of 30 -80 ℃ were studied by using Brookfield DV-III Ultra rheometer, LV1 rotor and 10 r/min rotating speed for measurement. The results showed that after a ultrasonic treatment to high total acid number crude oil under the optimal conditions of 240 W, 30 rain and 50 ℃, its viscosity reduced from 59.3 mPa · s to 39. 4 mPa · s and viscosity reduction rate reached 26.9%. After static time of 24 h at 50 ℃ , the viscosity of ultrasonic treated high total acid number crude oil reeoveried mainly.
