    QMWD Series Measurement While Drilling Tools

    The QMWD Series is a compact and modular measurement while drilling tool designed for efficient data transmission in directional and horizontal wells. Featuring low power consumption, easy on-site integration, and strong resistance to vibration and shock, this MWD system is ideal for demanding downhole environments.


    Power Supply

    Battery-powered

    Software Platform

    Windows OS

    Operating Temperature

    –20°C to 125°C


    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.
