摘要/Abstract

摘要： 利用电流变仪对某油田稠油乳化液进行了流变特性试验研究，以降黏率为评价指标，在高频/高压脉冲交流电场作用下，较为系统全面地探究了电场参数(电场强度、电场频率、占空比等)和非电场参数(温度、含水率、剪切速率等)对稠油流变特性的影响规律。利用正交试验设计方法，分别对比了电场参数和非电场参数对稠油流变特性的影响程度。结果表明：在电场参数中，电场强度的影响程度最大，其次是电场频率和占空比；在非电场参数中，温度的影响程度最大，然后是含水率和剪切速率。此外，进行了含砂稠油乳化液电流变试验，得到的最优电场强度和电场频率与不含砂稠油乳化液的相近。

Abstract: The electrorheological characteristics of heavy oil emulsion in an oilfield were experimentally studied by using an electrorheometer. Taking the viscosity reduction rate as the evaluation index, the influence of electric field parameters (electric field strength, electric field frequency, etc.) and non-electric field parameters (temperature, shearing rate, etc.) on the rheological characteristics of heavy oil was systematically and comprehensively explored under the action of high-frequency/high-voltage pulsed AC electric field. The orthogonal experimental design method was used to compare the influence of electric field parameters and non-electric field parameters on the rheological characteristics of heavy oil. The results showed that among the electric field parameters, the electric field strength had the greatest influence, followed by electric field frequency and duty cycle; among the non-electric field parameters, temperature had the greatest influence, followed by water content and shear rate. In addition, the electrorheological experiment of sand-containing heavy oil emulsion was carried out, and the optimal electric field strength and electric field frequency values obtained were similar to those of sand-free heavy oil emulsion.

Key words: water-in-oil emulsion, electrorheological characteristics, viscosity reduction rate, electric field strength, orthogonal experimental design
