| 为查明武川盆地的地热资源,利用地球物理方法寻找地下储水导热构造。通过分析研究区域岩石密度与磁性特征、布格重力异常分布特征和航磁特征圈定研究靶区。再通过开展可控源音频大地电磁、地震、地温测井等地球物理方法初步查明了勘查区地热赋存条件,研究了地热分布规律,圈定了地热异常区及地热有利开发范围,确定地热勘探孔井位,打出了地下低温热水,达到了勘查目的,取得了较好的地质效果。在利用常规地球物理方法分析武川盆地地热勘查的基础上,探讨了适合该地区的地热勘查方法。 |
| 英文摘要: |
| In order to find out the geothermal resources of the Wuchuan Basin, geophysical methods are used to find underground thermal conductivity structures. By analyzing the density and magnetic characteristics of rocks in the study area, the distribution characteristics of Bouguer gravity anomaly and aeromagnetic characteristics, the study target area is delineated.Then the geophysical conditions of geothermal occurrence in exploration area are preliminarily identified by means of controllable source audio magnetotelluric, seismic, geothermal logging and other geophysical methods.the geothermal distribution law was studied, the geothermal anomaly area and the geothermal favorable development range were delineated, the geothermal exploration hole position was determined, and the underground low-temperature hot water with a water temperature was reached. For the purpose of exploration, good geological effects have been achieved. Based on the analysis of geothermal exploration in Wuchuan Basin by conventional geophysical methods, the geothermal exploration method suitable for the area is discussed. |
