Generator
Generator Module: Stable Power for Telemetry
The generator module serves as a power source for the downhole telemetry system, providing up to 100 W of power. Its key function is to maintain stable, programmable voltage (from 20 to 38 V) for the equipment, regardless of fluctuations in mud flow rate.
Key Features and Advantages
  • Versatility and Autonomy: The module operates independently of communication with the telemetry system, allowing for easy integration into other complexes.
  • Intelligent Power Priority: Our solution automatically ensures current is drawn from the generator in priority over the battery via optimal voltage, extending battery life.
  • Self-Diagnostics: The built-in memory automatically saves operational parameters and service data, requiring no manual maintenance or clearing.
  • Easy Installation: The module design does not require special mounting, simplifying and accelerating its installation in the bottom-hole assembly.

DESIGN FEATURES
  • Universal Symmetry
  • The module's symmetrical design allows it to be rotated when assembling the drilling tool. This provides flexibility for precise sensor positioning: they can be moved away from magnetic interference or, conversely, brought closer to the bit for more accurate data.
  • Compact Technology Integration
  • Five measurement methods are combined within a single housing. This configuration significantly reduces the distance from the measurement point to the bottom hole, providing relevant data with minimal delay.
  • Bed Boundary Mapping
  • The module is equipped with probes for detecting bed boundaries with a range of up to 5 meters. The detection range adapts to well conditions and depends on the contrast in rock conductivity and the required accuracy.
  • Integrated Energy Storage
  • A special energy storage unit guarantees uninterrupted power for downhole tools, even under pulse load conditions. Thanks to it, power consumption spikes do not cause voltage sags in the line, ensuring stable operation of all equipment.
