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。
