Abstract: In order to optimize the magnetic coupling mechanism of underground radio energy transmission system in oil field, an improved solenoid type magnetic coupling mechanism is proposed for the magnetic coupling mechanism of the underground wireless power transmission system in the oil field. And an optimization design method is proposed by using the Maxwell electromagnetic field simulation tool. The characteristics of the LCC-S high-order compensation topology are studied. The compensation design formula and main circuit characteristics of LCC-S are obtained. Finally, the feasibility and correctness of the proposed coupling structure and compensation topology are verified by closed-loop PI ( Proportion Integration) control through PSIM ( Power Simulation) simulation software.

Key words: oilfield downhole, wireless power transmission(WPT), optimization design of magnetic coupling mechanism, electromagnetic simulation, LCC-S compensation topology
