| 摘 要： | 兰州新区地处秦王川盆地,盆地内具有地热形成的条件,地热成因兼有断裂构造控制型和沉积盆地型,具有较好的地热勘查前景。结合可控源音频大地电磁测深、大地电磁测深2种方法相互验证,查清了区内断裂构造,基底构造形态,为地热勘查提供了依据,避免了单一方法的片面性和盲目性。经钻孔验证勘查效果较好,为今后类似地区进行地热勘查提供了有价值的参考。

| Abstract: | Lanzhou New Area is located in Qinwangchuan Basin,which has the conditions of geothermal formation,and the geothermal genesis is controlled by faults and sedimentary basins,so it has good prospects for geothermal exploration. Combining the two methods of controllable source audio-frequency magnetotelluric sounding and magnetotelluric sounding,the fault structure and basement structure in the area are found out,which provides a basis for geothermal exploration and avoids the unilateral and blindness of single method. The drilling proves that the exploration effect is good,which provides valuable reference for geothermal exploration in similar areas in the future. |
