Problems solved by technology

[0002] The traditional electromagnetic forward modeling method in the frequency domain mainly uses the finite difference method, the calculation accuracy is limited, and only one parameter of resistivity is considered in the forward modeling. This method is not suitable for simulating underground structures, especially hydrothermal uranium deposits. The precision and accuracy of the real geological structure are relatively poor, and the simulation results will cause misunderstandings for field electromagnetic exploration processing and interpretation

Embodiment Construction

[0066] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Under the actual field geological conditions, the underground rock and ores all have the IP effect, and a single resistivity parameter cannot satisfy the petrophysical properties. At the same time, with the increase of depth, the pressure and temperature change greatly, and petrophysical experiments show that with the increase of temperature and pressure, the resistivity characteristics will also change, especially for deep elec...

Abstract

The invention relates to a method and a system for determining multi-parameter frequency domain electromagnetic abnormal response of uranium metallogenic elements, and belongs to the technical field of electromagnetic exploration data processing. According to the method, fine simulation of the interiors and boundaries of the uranium metallogenic elements is realized by adopting a mesh generation technology for the obtained geological profile map, and meanwhile, fine forward modeling response of the uranium metallogenic elements can be accurately obtained through finite element high-precision forward modeling calculation by utilizing the determined complex resistivity values of different mesh generation parts, so that the uranium metallogenic elements can be accurately simulated. And reasonable and accurate theoretical guidance is provided for field electromagnetic exploration and data processing.

Description

technical field [0001] The invention relates to the technical field of electromagnetic exploration data processing, in particular to a method and a system for determining a multi-parameter frequency-domain electromagnetic abnormal response of uranium metallogenic elements. Background technique [0002] The traditional frequency-domain electromagnetic forward modeling method mainly uses the finite difference method, which has limited calculation accuracy, and only considers the resistivity as a parameter in the forward modeling. This method is not suitable for simulating underground structures, especially hydrothermal uranium mines. The accuracy and accuracy of the real geological structure are relatively poor, and the simulation results will cause misunderstandings in the processing and interpretation of field electromagnetic exploration. SUMMARY OF THE INVENTION [0003] In order to solve the above problems existing in the prior art, the present invention provides a metho...
