The ZTMWD-NT wireless MWD system consists of a surface decoding system and downhole tools. All circuits in the downhole tools are manufactured using high-temperature MCM (Multi-Chip Module) technology, ensuring excellent long-term reliability and service time in high-temperature and high-vibration environments, with a maximum operating temperature of 150 ℃ . With high-precision compensation and calibration algorithms, the system achieves high-accuracy inclination and azimuth measurements across the entire temperature range and supports dynamic rotary measurements, to improve directional drilling efficiency. The system features a modular design with high-temperature rectangular connectors, and all hardware and software are independently developed. It offers strong scalability, allowing customization of mechanical and electrical interfaces to connect with resistivity tool, rotary steerable systems, and near-bit tool as per customer requirements. The driller’s display supports wireless communication, simplifying field wiring and enhancing operational efficiency. The battery pack supports real-time monitoring of power consumption.
