摘要

研究了影响起声波破乳脱水效果的两个因素;频率与声强。在试验的频率段范围内超声波频率对破乳的影响不是很明显,确定最佳频率为21kHz。对于不同的油样,声强与破乳脱水之间的规律变化较大:东辛落地油的最佳无量纲声强范围在0.065~0.108之间;东辛盐16块原油的最佳无量纲声强为0.108;孤岛三采油的最佳无量纲声强为0.374。

Abstract

This paper studies two factors affecting the demulsification and dehydration effect of ultrasonic wave:frequency and acoustic intensity. Research results indicates:the frequency of ultrasonic wave has little influence on the demulsification. and the optimum frequency is determined as 21 kHz; yet, the acoustic intensity can have great effect on the demulsification and dehydration for different oil samples. For example, the optimum dimensionless acoustic intensity for oil on the ground of Dongxin is 0.065-0.108, while for oil in Yan block 16 of Dongxin is 0.108, for oil in Gudaosancai is 0.374.
