原油乳状液对原油的长距离输运具有重要影响,乳状液的油、水状态及相互作用机制还需新理论和新方法获得新认识,基于有效介质理论,本文研究了原油乳状液太赫兹光谱响应特征.通过太赫兹时域光谱系统测试得到了含水率为0～28％的原油乳状液的太赫兹时域光谱,结合傅里叶变换计算了吸收系数和介电常数等光学参数,同一频率下吸收系数等光学参数随含水率增加而增大.样品的实际介电常数与Bruggeman理论计算的介电常数一致,最大误差率低于3％,说明含水率较小时,水分散在原油中,微粒间的距离较大,微粒间的相互作用力较小,随着含水率增加,水相和油相混合分布,微粒间的距离会变小,微粒的相互作用力会变大.因此,有效介质理论对乳状液的太赫兹光谱研究具有重要意义.
