七十年代初期就有人把积分变换理论中的希尔伯特变换方法引入到重磁场解释领域[2],后来逐渐进一步用于磁异常的定量解释。方法的基本特点都是利用磁异常曲线与其希尔伯特变换曲线的特殊特征交点,导出求解地质体的埋藏深度等参数解析表达式。然而,在实践应用中,上述方法有局限性。因为要得到理想的特征点是困难的,而且只利用个别点求出的参数其可靠程度也较差,特别是在解释区域磁测资料时,要求在每个测点上(或者任意点上)都能得到其地质体的产状参数。为此,我们提出一种在任意点上求解地质体产状参数的方法,以扩展上述方法的应用范围。这就是本文介绍给读者的目的。
In the early 1970s, some people introduced the Hilbert transformation method in the theory of integral transformation into the field of gravity and magnetic field interpretation [2], and then gradually used it for the quantitative interpretation of magnetic anomalies. The basic characteristic of the method is to use the intersection of the magnetic anomaly curve and its Hilbert transformation curve to derive the analytic expressions of parameters such as the depth of burial for the geological body. However, in practical applications, the above methods have limitations. Because it is difficult to obtain ideal feature points, and the parameters obtained using only individual points are also less reliable, especially when interpreting regional magnetic data, it is required that at each measurement point (or at any point) Can obtain the geological parameters of the geological body. To this end, we propose a method of solving the geophysical parameters at any point to extend the scope of application of the above method. This is the purpose of this article introduced to the reader.
