Embodiment

[0097] Such as Figure 4 As shown, between Qihe and Liaocheng Chiping, a multi-line source electrical source transient electromagnetic method survey line has been completed, with a total section length of 1.2km. Inversion results such as Figure 5 as shown,

[0098] The surface resistivity is low, and the stratification is good, which has a good reflection on the Quaternary and Neogene's extremely thick and low-resistivity overburden. As the depth increases, the resistivity increases gradually, showing obvious inhomogeneity. The relatively high-resistance and low-resistance contact zone near the survey line 1060m is the place where iron ore occurs. Drilling results such as Image 6 Show.

Abstract

The invention discloses a method for detecting a transverse magnetic polarized field with multi-wire sources and transient electromagnetism. The method comprises the following steps: laying one or more pairs of grounding conductive wire sources on the ground, and emitting a bipolar step current with an opposite direction to the underground through three grounding electrodes by each pair of conductive wire sources. The electromagnetic field observation can be performed on an apparatus with a pair of grounding conductive wire sources in the axial and equatorial directions. The electromagnetic field observation can be performed on an apparatus with multiple pairs of grounding conductive wire sources radially. The space structure of the underground electrical target body is obtained by performing inversion interpretation on the measured data. According to the method for detecting the transverse magnetic polarized field with the multi-wire sources and the transient electromagnetism, important pushing effect on improving the detection theory of a transient electromagnetism multi-polarized field and the detection ability of the transient electromagnetism on a high-resistance target body is realized, and a solid foundation for achieving fine detection of mineral resources, oil and gas resources in a second deep space is laid.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic exploration, and in particular relates to a detection method for a multi-line source transient electromagnetic transverse magnetic polarization field. Background technique [0002] According to the nature of the excitation field source, the transient electromagnetic method (TEM) is divided into magnetic source (loop source) and electrical source (ground wire source) TEM. Magnetic source TEM is sensitive to good conductors, and it is one of the most important means to detect good conductors such as coalfield hydrogeological exploration and groundwater. In addition to being sensitive to good conductors, electrical source TEM also has a certain ability to distinguish high-resistivity bodies. It has achieved good detection results in the fields of coalfield hydrogeological exploration for good conductor detection and oil and gas reservoir exploration for high-resistivity layer detection. . ...
