摘要：

Magnetotelluric detection is an efficient method, which is being tried to detect coalbed methane. However, the interpretation of electromagnetic signals for coalbed methane is now empirical. The forward and inversion modeling results obtained by only treating coalbed methane as a low-resistance body are not completely consistent with the measured data (such as radiation anomalies in specific frequency bands). We think the electromagnetic radiation of coalbed methane due to electrokinetic effect and piezoelectric effect should not be ignored. Starting with the simplified underground electric dipole model, we establishes a new electromagnetic model of coalbed methane to better match the measured data of coalbed methane reservoir regions.
