摘　　要：针对目前稠油开采和利用存在脱水、降粘难等问题,基于微波热效应与非热效应的原理,利用自行设计的微波辐射实验设备进行研究,系统分析了微波辐射功率和时间对脱水率的影响,以及辐射对胶质和沥青质的影响,并详细介绍了微波辐射工艺中的具体流程。结果表明:微波辐射平均脱水率为90.7%,与普通加热脱水技术的脱水率为34.8%相比,脱水效率高;频率为915 MHz、功率为1 k W的微波作用1min后(热效应),油样温度迅速升高到71.2℃,反应速度快;微波辐射(非热效应)后运用四组分测定法,测得油样中沥青质含量减少了2.5%和胶质含量减少了1.2%,油样粘度在低温区发生明显的改变。研究结论为该项技术在工业应用中提供了重要的参考和展望,证明了该技术具有良好的应用前景。Aiming at the problem of high viscosity and difficult dehydration of the heavy oil during the exploitation and utilization,based on the principle of microwave thermal effect and non-thermal effect,it is investigated by using high power microwave radiationexperimental equipment designed by ourselves,and analysed on influence of microwave radiation power and time on the dehydrationrate,radiation effect on resin and asphaltene,and described in detail the process of technology. The results showed that：microwave de-hydration is 90.7% on average,the microwave technology compared with conventional heating technology,which is 34.8% on average,microwave dehydration rate is much greater than conventional heating technology;After frequency of 915 MHz,1 k W power microwaveradiation for 1min（thermal effects）,temperature quickly raises to 71.2 ℃,fast response;after microwave radiation（non-thermal ef-fect）,using SARA determination method,the oil sample asphaltene content is reduced by 2.5% and resin content is reduced by 1.2%,oil viscosity changed significantly in the low temperature region. It is shown that microwave technology provides an important referenceand has a better application prospect in the field.
