摘要

高频电磁波采油工艺复杂,经济风险大,通过各种模拟方法认识油藏内流体运动的规律具有重要意义。利用数值模拟方法,通过将电磁场、温度场与渗流场进行耦合,对平面一维径向系统中的高频电磁波加热采油机理、影响因素及温度场、压力场与流体饱和度场的分布进行研究,同时,将其与物理模拟及解析计算结果进行对比验证,为高频电磁波加热采油提供理论依据。

Abstract

Oil recovering technology by high-frequency electromagnetic heating is complicated,so it is very important to study the flow trend of reservoir fluid by all kinds of simulating. In this paper,mathematical simulation is used and electromagnetic field,vadose field and temperature field are coupled. By numerical simulation,the distribution of temperature,pressure and saturation are studied in the radial system of one dimension. The numerical solution is contrasted to the analytic solution,experimental data and external document to verify the soundness of modeling and calculating。
