| 摘 要： | 地-井TEM法（瞬变电磁法）是一种寻找深部隐伏良导体的有效方法。以新疆白石泉铜镍矿区zk506孔三分量井中瞬变电磁测量为例，结合钻孔已知信息，通过分析曲线特征，从上至下共划定了3个异常，并推测第2个异常为主要异常，确定其方位为东南，同时根据z分量响应在晚期还有较强的幅值，判断异常在东南方向上具有相对长的延展，最后通过与zk506孔以及后期施工的zk507、zk508孔的地质编录对比，验证了地-井TEM解译推断，修正了之前zk506孔单孔编录的地质认识，证明了井中瞬变电磁法在良导硫化物矿勘探中的有效性和重要性。

Typical characteristics analysis and anomalies interpretation of borehole TEM: Taking Xinjiang Baishiquan Cu-Ni ore zk506 borehole as an example |

| Abstract: | Borehole TEM method is an effective method for the deep buried conductive sulfide ore, this research took three component transient electromagnetic measurement in borehole zk506 in Xinjiang Baishiquan Cu-Ni ore as an example, combined with the known information of the borehole, through the analysis of features of the curves, marked off three anomalies from top to bottom and speculated that the second was the main anomaly, determined that its azimuth was southeast, and judged that the anomaly extended far in the southeast direction according to the high amplitude of response of component z in the later period. Finally, comparison of the geological logging of borehole zk506 and later drilled boreholes zk507 and zk508 proved the inference and the interpretation of borehole TEM, revised previous geological knowledge based on the single record of the borehole zk506. The validity and the importance of borehole transient electromagnetic method in the exploration of sulfide deposits with good conductivity are testified. |
