摘　　要：针对大庆高稠油脱水困难的现状,采用添加钠盐的方法进行微波辐射脱水。结果表明,添加微量的钠盐能显著提高稠油乳状液的脱水效果。研究了钠盐存在下微波辐射高稠油乳状液脱水的机理,在此基础上,采用CH_3COONa作为添加剂,用正交实验设计法考察微波辐射高稠油乳状液脱水的最佳实验条件。通过极差和方差分析可知,在影响大庆原油乳状液脱水率的4个因素中,CH_3COONa浓度影响最大,其余依次为:系统压力、恒压时间、辐射功率。在CH_3COONa浓度0.4mol/L,系统压力0.1MPa,恒压时间3min,微波辐射功率600W时,含湿量为50%的大庆原油乳状液的平均脱水率达97.53%。According to the nature and the difficulty of dehydration of Daqing high-viscosity crude oil, the process of dehydration by microwave radiation in the presence of sodium salts was studied. The resuits indicated that the dehydration efficiency was greatly improved by sodium salts and that the order of the influences of the factors were quantity of CH3COONa, pressure, radiation time, and radiation power. The average dehydration rate of Daqing high-viscosity crude oil with water content of 50% was up to 9 7. 5 3 % under the conditions of 0. 4 mol / L CH3 COONa , 0. 1 MPa , radiation time 3 minand radiation power 600 W.
