Example Embodiment

[0026] In order to make the purpose, technical solutions, and beneficial effects of the present invention clearer, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments and the embodiments in the present application The features in can be combined with each other arbitrarily.

[0027] The schematic diagram of the MTEM data acquisition system is as Figure 1A Shown. The acquisition system transmits the source current to the ground through the source electrode, and adopts the receiving electric dipole array to receive the voltage signal in the axial direction of the source electric dipole during the transmission of the source signal.

[0028] In the prior art, a multi-channel transient electromagnetic transmitter transmits a PRBS signal. The receiver receives this excitation source signal, performs deconvolution processing on the received excitation source si...

Abstract

The application relates to an inversion method and an apparatus for multi-channel transient electromagnetic detection data. The method incudes: multi-channel transient electromagnetic detection is performed at a to-be-detected place so that earth pulse response of the to-be-detected place is obtained; the falling-edge step response of the earth pulse response is obtained; and the inversion of the falling-edge step response is performed. According to the inversion method and the apparatus for the multi-channel transient electromagnetic detection data, the interferences of air waves in the pulse response can be avoided, accurate inversion results can be obtained, and the falling-edge step response obtained by a reverse integral method and the analytical solution are well coincided.

Description

technical field [0001] The invention relates to the field of electromagnetic technology, in particular to an inversion method and device for multi-channel transient electromagnetic detection data. Background technique [0002] Transient electromagnetic method is a time-domain artificial source electromagnetic method, which is widely used in the detection of metal ore, oil, coal and other energy sources. At present, the shallow resources are exhausted, and the exploration of deep resources has become a trend. The detection depth and detection accuracy of the traditional transient electromagnetic method are difficult to meet the requirements of deep resource detection. It is imminent to develop new technologies and equipment for large-depth detection of transient electromagnetic method. Wright of the University of Edinburgh proposed a new technology of multi-channel transient electromagnetic method (Multi-channelTransientElectromagneticmethod, MTEM). Compared with the tradit...
