Abstract

In this paper, the effect of ultrasonic wave was evaluated on viscosity and pour point of heavy oil. The effects of time, temperature and power on the viscosity reduction of heavy oil were tested at first. The results showed that ultrasonic wave can reduce the viscosity of the heavy oil from Jinghe Oilfield effectively with the highest viscosity reduction of 87.2%. Then the pour point depressing was evaluated to find the highest pour point depression of 4.8°C. Partly recovering of the viscosity after ultrasonic treatment, the paraffin crystal morphology analysis was conducted on the heavy oil to elucidate the mechanism of viscosity reduction and pour point depression.

超声波降低稠油粘度

摘要

本文研究了超声波对重油粘度和倾点的影响。首先测试了时间，温度和功率对重油粘度降低的影响。结果表明，超声波可以有效降低Jing河油田稠油的黏度，最高黏度降低率为87.2％。然后评估倾点下降，以发现最高倾点下降为4.8°C。超声处理后部分恢复了粘度，对重油进行了石蜡晶体形态分析，以阐明粘度降低和倾点降低的机理。
