The High-Speed Shear Valve is a core component of the Measurement-While-Drilling (MWD) system. It generates pressure pulse signals by periodically shearing drilling fluid, transmitting downhole engineering parameters (e.g., inclination, azimuth, temperature) and geological parameters (e.g., gamma, formation resistivity) to the surface in real time, providing critical data support for drilling decisions.

Tool Advantages

Fast signal transmission, reaching over 3 bits per second.

Optimized drive circuit design with low power consumption; a single battery pack, paired with a directional probe, offers a lifespan exceeding 350 hours; open flow channel design, easy to flush, with surfaces coated with special wear-resistant materials for long service life.

Six-lobe stator-rotor structure, enabling faster switching speeds under the same conditions.

High-speed, lightweight design for drive motor and components, ensuring faster operation and greater energy efficiency.

Drive circuit with anti-jamming design; in extreme cases where the rotor is completely stuck by debris, the circuit activates a protection program to safeguard the motor and components.

Stator-rotor with anti-blocking design, resistant to jamming under conventional drilling with sealing operations.
