“…Traditional geometric factor theory is derived from the electromagnetic field equations under the conditions that ignoring the impact between the eddy skin effects [4]. In actual logging, due to the nonlinearity of skin effects, people cannot execute surrounding rock effect correction by use of the geometric factor [5]. Therefore, the study on skin effects of eddy currents in lossy layered dielectric formation has important implications for the calculation of true formation conductivity.…”

The study of induced eddy skin effects plays an important role to determine the reservoir distribution. This paper calculated the apparent conductivity of loss stratum by the use of geometrical factor theory and skin effects theory. The numerical results show that the skin effect theory has higher accuracy due to the consideration of the interaction between the induced eddy currents. And it is also easy to spread in use of inhomogeneous media. These conclusions provide a theoretical basis for the analysis of electromagnetic response characteristics in lossy multilayered stratum.

“…Traditional induction logging measure secondary fields which contain stratigraphic information through receiving coil electromotive force, secondary fields are weaker than relative to direct coupling signal, then exploration effect is poorer with low vertical resolution and shallow detecting depth in complex geological structure. Array electric logging instrument consists of multiple transmitting and receiving coils, logging curves can be obtained [6][7][8][9].…”

Abstract. Multi-frequency array induction logging method using a combination of high and low frequency can keep both vertical stratification and probing depth capabilities of logging instrument, and in order to reach a certain field strength in strata, the transmission circuit need provide greater current to the transmitter coil system. This paper studied resonant multi-frequency electrical logging system using resonant transmission mode, it mainly researched multi-frequency, high-frequency signal generator unit, power amplifier unit and analysed induced electromotive force calculation method of receiving coil. Combining the transmission and reception experiment, parameters such as the emission current and induced electromotive force of receiving coil have been achieved, those can verify theoretical derivation. The paper provides good design method of excitation source and analysis of receiving characteristics, at the meanwhile, it can play an important role in development and application of multi-frequency array electrical logging methods.
