ZSZM16 Mine-Used Measurement-While-Drilling (MWD) System
Primary Applications:
The ZSZM16 MWD system is primarily used for real-time monitoring during the construction of near-horizontal directional boreholes in underground coal mines. It transmits borehole parameters such as inclination angle, azimuth angle, and tool face angle via mud pulse mechanical waves while simultaneously displaying borehole parameters and trajectory in real time. This allows drilling operators to continuously monitor the borehole construction status and promptly adjust the orientation angle of the downhole motor or other process parameters to achieve precise drilling.
Scope of Application:
Suitable for directional borehole construction in various coal and rock formations with a hardness coefficient of 0.5 < f ≤ 10.
Ideal for gas hazard control, water hazard control, stress relief, and disaster mitigation operations.
Specifically designed for directional borehole construction in coal seams or rock formations with borehole depths ranging from 800 to 2500 meters, particularly for gas hazard and water hazard control.
Compatible with both semi-automatic and fully automatic directional drilling rigs for directional drilling operations.
Also applicable for geological exploration, coalbed methane, and shale gas drilling projects.
Technical Features:
The first domestically developed mud pulse MWD system in the mining industry with a minimum diameter of φ40mm.
Stable and reliable communication transmission under flow rates of no less than 150 L/min.
Maximum communication transmission distance ≥ 3500 meters.
Battery life exceeds 30 days.
