    Abstract:

    The near-bit measurement while drilling (MWD) system effectively avoids the data latency issues faced by traditional MWD systems, and antenna parameter design and optimization are crucial for improving signal transmission distance and stability. This paper presents an optimization study on the antenna parameters of a near-bit MWD system, exploring the relationships between antenna coil diameter, number of turns, load, and magnetic core with signal transmission distance through experiments. The results show that with an emitting coil of 100 turns and a diameter of 0.8mm, and a receiving coil of 180 turns and a diameter of 1.0mm, combined with a secondary power amplifier circuit and the use of ferrite cores or ferrite sheets, the signal transmission distance and stability are optimal. The research findings provide theoretical basis and practical guidance for optimizing the antenna design of near-bit MWD systems.
