| 摘 要： | 为了提高瞬变电磁法的探测深度，在青城子矿集区开展了大定源装置条件下基于线圈传感器和高温超导传感器的瞬变电磁法实验工作.结果表明:利用高温超导传感器直接测量磁场具有低噪声、高灵敏度、低频响应好的特点，晚期信噪比高且对深部低阻响应敏感的优点.在相同激发条件和低噪声背景条件下，基于高温超导传感器的瞬变电磁法在青城子矿集区探测深度可达到1 800 m左右，较传统线圈传感器反演深度提高50%，该方法能有效地提高瞬变电磁法探测深度.

| Abstract: | In order to improve the detection depth of TEM, the TEM experiment based on HTS sensor was carried out in Qingchengzi ore-concentrated area. The results show that the HTS sensor has the advantages of low noise, high sensitivity and good response at low frequency. Under the same excitation condition and low noise background, the detection depth of TEM based on HTS sensor in Qingchengzi ore-concentrated area can reach about 1 800 m, which is 50% higher than that of conventional coil sensor, indicating this method can effectively improve the detection depth of TEM. |
