高温岩体地热资源模拟与预测方法
SIMULATION AND FORECAST METHOD OF GEOTHERMAL RESOURCES IN HOT DRY ROCK
【摘要】 研究了基于三维稳态热传导理论并忽略对流换热及地质构造等次要因素影响的地温场与地温梯度场的反演方法。该方法可以在大尺度上数值模拟岩体中地温的空间分布状况,并预测高温岩体地热资源量。以云南省腾冲热海热田为例,模拟和分析了地质体的地温与地温分布梯度场的特点及其形成原因,并对热田高温岩体地热资源量进行了预测评价。提出的高温岩体地热资源模拟与预测方法具有重要的理论价值,研究结果可为热海热田地热资源的开发和利用提供参考。
【Abstract】 The inversion methods of ground temperature field and ground temperature gradient field based on three-dimensional static heat conduction theory are presented with the influence from those minor factors such as heat convection and geology tectonics and so on. It can be used to simulate the three-dimensional ground temperature field in rock mass and to forecast the geothermal resources quantity of hot dry rock(HDR) on large scale. The paper analyzed the features and the mechanisms of ground temperature field and ground temperature gradient field of Rehai geothermal field in Tengchong,Yunnan province,China. Then the quantity of HDR geothermal resources was forecasted,and the results achieved from the presented simulation and forecast method of HDR geothermal resources of Rehai geothermal field can provide a reference to the geothermal exploitations.
