Abstract: Geothermal resources is a new type of non-pollution energy,with a high value of exploitation.For their special geological conditions,basins always contain abundant geothermal resources, which are easy to exploit and use.However,there is only little and poor means and technology in geothermal exploitation.The technology of geothermal field modelling for oil and gas is almost mature and widely used in reservoir modelling.It can be used to improve the precision of exploitation.In this paper,the author discusses an experimental mathematic model based on temperature control equation and groundwater current equation to simulate the geothermal resourcs of basin.
