摘要
在模拟研究井中瞬变电磁响应特征的基础上,提出井中瞬变电磁纯异常提取方法 ,并将其应用于诸广热液型铀成矿区ZK71-2钻孔井中瞬变电磁实测数据处理,识别了井旁盲赤铁矿(化)一处,精确定位了赤铁矿(化)中心的位置。同时,针对γ测井揭露的放射性异常,通过对异常段的纯异常提取,推测了钻孔中铀矿化可能的延伸方向。
Based on the simulation and research of BHTEM response characteristics,pure anomaly extraction method in BHTEM was proposed and used in the data processing of BHTEM data in ZK71-2 in Zhuguang hydrothermal uranium area.With this method,we identified blind hematite anomaly near the hole,and precisely located the position of hematite mineralization center.For the radioactivity anomaly exposed byγlogging.By extracting the pure anomalies in anomaly depth segment,we inferred the possible extending direction of uranium mineralization in boreholes.
