盆地地热场模拟在地热资源勘探中的应用

THE TECHNOLOGY OF BASIN GEOTHERMAL FIELD MODELLING USED IN GEOTHERMAL RESOURCES EXPLOITATION

地热资源是一种新型无污染能源,具有极高的开采价值,已经受到世界各国的关注.盆地因其特殊的地质条件,内部往往蕴涵着丰富的地热资源,且具有易开采、利用的特点.但目前地热资源勘探的手段和研究方法单一,制约着地热资源的开采与开发.而盆地地热场模拟技术已经较为成熟,并在油气成藏模拟中广泛应用.我们可以在已有的技术手段下结合盆地地热模拟技术来提高勘探的精度.本文还探讨了以地温控制方程与地下热水水流方程相结合来建立模型,模拟盆地地热资源.

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.
