两个磁性体磁异常物理模拟及数据处理与转换研究

The physical simulation experiments effect of two magnetic body magnetic anomaly and the research of data processing and transformation

为了探讨磁异常中正负异常形成的规律,开展强磁铁平面模拟实验及等值线制作工作,为了准确数据判断磁性体空间位置及个数,开展分量转换、化极、求导等数据处理数及转换工作。最后得出:①磁化方向的不同是形成正负异常的根源;②将△Z分量转换数据用于垂直二阶导数计算,能更加准确确定磁性体的空间位置及个数。

In this paper, in order to explore the magnetic anomalies in the form of positive or negative anomaly, a strong magnet plane simulation experiment and contour mapping was carried out. In order to accurately judge the space location and the number of magnets, the component conversion, reduction to the pole, derivation, etc data processing and conversion work were carried out. Finally it was obtained that.. ①Different magnetization direction is to form a source of positive and negative anomalies. ② Using △Z component conversion data for the calculation of the vertical second derivative could more accurately determine the spatial posi- tion and number of the magnetic bodies.
