Abstract

Transient Electromagnetic Method (TEM), as a time-domain active source electromagnetic method, has been successfully applied in multiple fields and has great potential for development in deep resource exploration. To further explore whether multi-component detection is beneficial for increasing detection depth, this article first starts from the TEM three component method and derives an approximate expression for the late three component response in detail; Secondly, by combining approximate expression independent variables, the attenuation characteristics of the y and z components in deep detection under different receiving and transmitting distances are studied; Finally, taking the geological conditions of the oil and gas reservoir as a reference, a qualitative analysis was conducted on the detection depth of the two components of the magnetic field. The research results indicate that the y-component is an effective TEM method for receiving components, and the signal strength is closely related to the transmitting and receiving distance. At an appropriate transmitting and receiving distance, the y-component can compensate for the fast attenuation of the z-component in the later stage. Two component reception can improve the signal-to-noise ratio of TEM detection and reduce the multiplicity of inversion solutions.
