摘要
论述了地下温度和电阻率之间的关系,在较小范围工区内(考虑测井资料的情况下),利用可控源音频大地电磁测深反演电阻率预测地热田深部温度,探讨了该方法的实际应用效果。事实证明,由可控源音频大地电磁测深数据进行反演得到的电阻率分布,不仅能够探测地层埋深和断裂构造的空间分布情况,而且在一定条件下可以推断热储构造的温度。
The resistivity inversed by the CSAMT method can be used to detect the depth of the strata and deduce the spatial distribution of faults,and even predict the temperature of the thermal structure in some cases.Based on a discussion of the relationship between the underground temperature and the resistivity of the structure,this paper demonstrated the use of the distribution of resistivity inversion to predict the temperature of the geothermal field under certain conditions（with the consideration of the logging data）,and the application results show the effectiveness of the technique.
