摘　　要：阻抗谱或者介电谱测量是一种迅速的、非侵入的测量手段。国外的石油方向研究学者对介电技术的应用十分广泛。本文针对原油生产与运输中常见的问题,综述了介电谱在石油科学领域的研究进展:沥青质发生聚集或者絮凝前后,油样的介电性质会发生显著变化;原油乳状液稳定性与其电学性质密切相关;原油的流动性质与其电学性质之间存在定量关系。最后本文推荐了今后研究的方向:介电的角度研究蜡对原油流变性质的影响。Dielectric spectroscopy or impedance is a rapid and non-invasive measurement method.The application of dielectric technology by foreign researchers is very extensive.In view of the common problems in crude oil production and transportation,the research progress of dielectric spectroscopy in the field of petroleum science was reviewed.The dielectric properties of the oil sample change significantly as the asphaltenes aggregate or flocculate.There is a quantitative relationship between the flow properties of crude oil and its dielectric properties.The stability of crude oil emulsions is closely related to its dielectric properties.Finally,directions in the following research were pointed out,such as:study on the influence of wax on the rheological properties of crude oil from the perspective of dielectric.
