The invention discloses an electromagnetic method and device for obtaining apparent resistivity based on space total magnetic field intensity. The method comprises the following steps: controlling a transmitter in a pre-arranged field source to transmit a current signal through two electrodes; acquiring two horizontal magnetic field signals and a vertical magnetic field signal of a measuring point at the measuring point; acquiring a total magnetic field of the measuring point according to the two horizontal magnetic field signals and the vertical magnetic field signal; obtaining a function relationship between the total magnetic field and the apparent resistivity; and calculating the apparent resistivity of the measuring point at each frequency according to the function relationship between the total magnetic field and the apparent resistivity. According to the method and the device, the problems of high sensor arrangement requirement and large magnetic field error in apparent resistivity acquisition in the prior art are solved, so that the construction pressure is reduced, and the accuracy of the apparent resistivity is improved.
Description
technical field [0001] The present application relates to the field of apparent resistivity processing, and in particular, to an electromagnetic method and apparatus for obtaining apparent resistivity based on the intensity of the total magnetic field in space. Background technique [0002] The calculation of apparent resistivity is an important part of the electromagnetic exploration method, and the apparent resistivity contains the electrical information of the underground medium. For a long time, the wide-area electromagnetic method has used a single-component horizontal electric field E to obtain apparent resistivity in practical applications. By arranging a field source on the surface, an artificial electromagnetic field is established. x The calculation of apparent resistivity is carried out, but there is little research on the application of magnetic field, especially when the ground conditions are poor and the electric field cannot be measured, the use of the strong ...
