The invention belongs to the geophysical gravity and magnetic
data processing field and relates to a method for quickly inversing the spatial position of an underground geologic body. The method includes the following steps that: step 1, magnetic measurement data are obtained; step 2, measuring point anomaly
Delta T values are obtained; step 3, gridding
processing is performed on the measuring point anomaly
Delta T values; step 4, a reduction-to-pole anomaly
Delta T value grid and an X-direction, Y-direction and Z-direction derivative grid are obtained; step 5, the grids are segmented; step 6, Euler solutions in small grids are obtained; step 7, a small grid Euler solution set is extracted; and step 8, a final interpretation result map is obtained. With the method provided by the technical schemes of the present invention adopted, inversion speculation can be performed on the underground geologic body, so that the actual geological characteristics of the underground geologic body can be reflected, the
distribution law of the underground geological body can be effectively evaluated, and therefore, underground mineral resources can be rapidly and accurately explored. The method is of great significance for geological
prospecting work.
