GDQ-2D Integrated Digital Logging System
Revolutionizing Subsurface Exploration with Precision and Modularity
The GDQ-2D Integrated Digital Logging System represents a breakthrough in geophysical and borehole surveying technology. Designed for versatility across industries-including coal mining, oilfields, hydrogeology, and metallurgical exploration-this system combines advanced modular architecture, full downhole digitization, and ultra-portable hardware to deliver unmatched performance.
Core Innovations & Competitive Advantages
Modular Design for Enhanced Flexibility
Every component, from surface units to downhole probes, adheres to standardized modular principles. This ensures 100% compatibility across accessories, simplified maintenance, and effortless scalability. Users can switch probes as easily as replacing a lightbulb, eliminating downtime for recalibration.
Downhole Digital Encoding for Signal Integrity
Unlike analog systems, GDQ-2D employs A/D conversion and forward error correction for all downhole signals. Bidirectional communication with the surface unit guarantees real-time control via PC and zero signal degradation, even in high-interference environments.
Oversampling Technology for Maximum Data Resolution
By dynamically adjusting oversampling rates based on logging speed, the system captures ultra-high-resolution formation data. This enables precise digital filtering, spatial analysis, and noise elimination-critical for identifying subtle geological features.
Compact, High-Pressure Downhole Probes
Probes feature Φ40/50mm diameters and 1,000-1,500mm lengths, constructed from stainless steel. Standard models withstand 20-40MPa pressure and 70-90°C temperatures, with custom options reaching 60MPa/120°C for extreme environments.
Applications Across Industries
Coal & Metal Mining: Detect ore boundaries, density variations, and structural anomalies.
Hydrogeology: Map aquifers, monitor water quality, and assess well integrity.
Oil & Gas: Perform production profiling, casing inspection, and reservoir evaluation.
Environmental Surveys: Track pollutant migration and subsurface conditions.
