QMWD is a high-performance wireless MWD machine that combines simplicity, stability, and cost-efficiency. With a maximum working temperature of 125°C and a pressure rating of up to 120 MPa, it delivers accurate real-time measurements of inclination, azimuth, and toolface angle under harsh drilling conditions. The battery-powered system ensures flexible deployment and is suitable for wells with limited telemetry signal modulation tolerance.
