摘　　要：讨论三分量磁测的数据处理方法、异常分离、合并的原则及其处理方法。由一组井中三分量磁测的实例可看出,分离得到是具体的层信息,合并可使解释工作简化,异常的空间关系更加明朗,结合地质资料进行综合分析,就会得出满意的解。This paper deals with the data-processing technique as well as the principle and method of anomaly separation and combination. A practical example of borehole three-component magnetic survey shows that ＂ separation＂ can give concrete layer information, and ＂combination＂ can simplify the interpretation work and make clear the spatial relationship between the anomalies. Satisfactory results can be obtained with the help of an integrated analysis of geological information.
