摘　　要：采用辐射技术对模拟样品进行原油降粘与脱水实验，考察水浴、微波与超声波作用温度和时间对原油粘度和含水率的影响．在优化条件下，超声与微波破乳效果好于水浴，当超声温度为70℃、处理9min时，最大降粘率为72％；微波温度60℃保持11min，最大降粘率为64．7％．辐射技术可有效促进油水分离，微波温度50-60℃下作用4-5min时，脱水率最大达60％；超声温度55℃下作用11min时脱水率达65％，超声脱水效果明显．Radiation techniques were used for reduction of the viscosity and dehydration of raw oil sample. The effects of temperature and time of water bath, microwave and ultrasonic wave on the viscosity and water content of raw oil sample were examined. The results indicated that ultrasonic wave and microwave showed a better efficiency than water bath. The reduction rate of viscosity was 72% by the treatment of ultrasonic wave at 60 ℃ for 11 rain, and 64.7% by the treatment of microwave at 70 ℃ for 9 rain. These results are better than those previously reported.
