摘要
电磁加热开采稠油和沥青技术已经成为一个非常有前景的开采工艺,该技术是将电场能或高频电磁场能输入地层,依靠低频电阻热损耗生热机制或高频介质极化生热机制加热油层,通过提高油层温度来降低原油粘度。与其它的采油工艺相比,电磁加热技术既没有在井筒中的热损失,也不受地层低渗透率的影响,具有环境友好的特点。详细综述了国内外电磁加热开采稠油和沥青技术的最新发展现状,探讨了电磁加热开采稠油和沥青技术机理,评述了电磁加热开采稠油和沥青技术优点及技术局限性,展望了电磁加热开采稠油和沥青技术应用前景并提出了今后的发展方向。
The electromagnetic heating of heavy oil and bitumen is a promising mining technique that can inject electric energy or high-frequency electromagnetic into stratum. Heavy oil and bitumen reservoir is heated by electrical resistance heating and the polarization of high-frequency dielectric to increase reservoir temperature and reduce the viscosity of crude oil. Compared to other technologies, there is no heat loss in the wellbore, and it is not affected by the low permeability. Main advantage of the technology is environmentally friendly. In this paper, the present situation of the development of electromagnetic heating of heavy oil and bitumen was summarized, and mechanism of the technology was discussed, on the other hand, advantages and technical limitations of the technology were reviewed, and the development direction in the future was analyzed.
