Abstract

The invention discloses a two-dimensional body magnetic field value calculation method which comprises two main steps, namely complex two-dimensional body model expression and rectangular model magnetic field calculation. Under specific complex two-dimensional body model expression mode conditions, a rectangular two-dimensional body magnetic field overlapping model is established, according to a designed weighting coefficient calculation equation, a rapid one-dimensional discrete convolution algorithm is adopted, and unification of efficiency and precision of magnetic field calculation is achieved. By adopting the method, the problems that a conventional two-dimensional body magnetic field value calculation method cannot simultaneously ensure calculation efficiency and calculation precision and requirements of fine inversion imaging of large-scale magnetic field data magnetic susceptibility and man-machine interaction modeling and interpretation cannot be met can be solved.

Description

technical field [0001] The invention relates to a numerical calculation method for a two-dimensional body magnetic field, in particular to a fast and high-precision numerical calculation method for a two-dimensional body magnetic field with any cross-sectional shape and arbitrary magnetic susceptibility distribution. Background technique [0002] Magnetic prospecting is based on the earth's magnetic field and the difference in magnetic susceptibility as the physical basis. It is a geophysical prospecting method for studying the earth's structure and searching for solid mineral resources. There are no too many conditions. In actual exploration work, such a linear geological body is common: the scale of its strike direction is much larger than the scale perpendicular to its strike direction. For such geological bodies, the actual source distribution can be replaced by a two-dimensional body extending infinitely in the strike direction. [0003] With the development of sensors...
