Features & Benefits of 0-1000M Geophysical Resistivity SP Gamma Borehole Logging Equipment Water Well Logging Equipment
1. Standardization and modularity
In the GDQ-2D integrated digital control logging system, both hardware and software, no matter probe or ground box, signal measurement or signal transmission, have adopted the standardization and modularization design concept. The benefits of standardization and modularity Product is excellent in products' consistency , maintainability and reliability. It is convenient to operate and maintain. The accessories are 100 percent universal and can be expanded at any time.
2. Fully underground digital and measurement's signal transmission
All the signals from the underground probe are converted by A/D and sent to the ground after being encoded. The underground probe is a two-way street communication. Digital code transmission measurements greatly improve the anti-jamming capability, and the system itself can correct the error code, which guarantees the quality of the signal transmission.
3. Oversampling technology to obtain the most formation information
GDQ-2D Logging System uses the sampling method for the collection of formation information. The oversampling amount increases with the decrease of the logging speed, and over sampling ensures the need for digital filtering, enhancing spatial resolution and screening useful information.
4. Small size of the underground probe with high pressure
GDQ-2D Logging System probe is almost diameter Φ40 and Φ50 mm, the appearance of length 1000~1500mm size. The probe is made of stainless steel. Resistance to 20~40 MPa water pressure, temperature of 70 ~ 90 ºC. Special orders can be 60 MPa water pressure resistance, temperature 120 ºC resistance.

Electrical SP Resistivity Water Welll Logging Equipment Geophysical Tool
The instrument should be placed in the open space in the field. The space should be flat and dry land. It is about 10 meters from the winch to the well.
The pulley should be firmly fixed on the frame before setting on the well, so as not to loose the frame into the well. Then, connect 4 lines on the logger box, which is the power cord, USB line, depth encoder line, and collector ring line.
