本文建立了无限水平柱体的总磁异常之解释方法。同传统的异常解释方法(特征点法和积分法)相比较,本方法具有以下几个特点。首先,所提出的特征点法和积分法适合于任意磁化水平柱体的总磁异常的解释,这一点对于海上磁法勘探的资料解释具有一定的意义。因为海上磁测通量是测得总磁异常。其次,所提出的特征点法可以用来确定与柱体中心位置相对应的在剖面上的带影点。也说是坐标原点。再者,所提出的特征点法和积分法可用来计算水平柱体中心的深度,而在积分反演中只用到磁异常曲线的一部分。这一点同其他积分法相比,其计算过程比较简单。最后,也作了理论模型的正反演计算。反演结果表明,所提出的方法构能给出满意的反演结果。
In this paper, a method to explain the total magnetic anomaly of an infinite horizontal cylinder is established. Compared with the traditional method of abnormal interpretation (feature point method and integral method), this method has the following characteristics. First of all, the proposed method of feature point and integration is suitable for the interpretation of the total magnetic anomalies in any magnetized horizontal cylinder, which has some significance for the data interpretation of marine magnetic exploration. Because the sea magnetic flux is measured total magnetic anomaly. Secondly, the proposed feature point method can be used to determine the shadow point in the section corresponding to the central position of the cylinder. Also said that the origin of coordinates. Furthermore, the proposed feature point method and integration method can be used to calculate the depth of the horizontal cylinder center, and only use part of the magnetic anomaly curve in the integral inversion. This point compared with other integral method, the calculation process is relatively simple. Finally, also made the theoretical model of inversion calculation. The inversion results show that the proposed method can give satisfactory inversion results.
