老化油超声波降黏实验探讨

Experimental study on the viscosity reduction by ultrasonic wave for aged oil

为了解决老化油在集输系统无效循环及占用储罐有效库存等问题,开展了老化油超声波降黏技术研究。通过开展室内实验,对老化油在不同温度、超声波功率、振动方式下的物理性质进行探讨分析。实验结果表明:在外输温度为46℃,超声波作用于介质2min且功率达到2kW时,对比采用超声降黏处理过的老化油和未处理的老化油降黏率可达45. 2%,表明超声波振动能够提高老化油的流动性。超声波降黏技术可以为油田站场内平稳集输提供技术支撑。

In order to solve such problems as ineffective circulation of aged oil in gathering and transmission system and effective stock of storage tank being occupied,the technology of viscosity reduction by ultrasonic wave for aged oil has been studied.The indoor experiments were carried out to discuss and analyze the physical properties of aged oil under different temperatures,ultrasonic powers and vibration modes.Experimental results showed that the viscosity reduction rate of aged oil treated by ultrasonic wave was lowered by 45.2%compared with that of untreated aged oil under the transporting temperature of 46℃and ultrasonic wave keeping on the medium for 2 minutes with power up to 2 kW,it shows that ultrasonic vibration can improve the fluidity of aged oil.The technology of ultrasonic viscosity reduction can provide technical support for stable gathering and transmission of oilfield station.
