JMZD-2D Density Gamma SP Laterolog Resistivity Caliper Geophysical Borehole Logger Water Well equipment Well Logging Equipment for Underground Water Detection
JMZD-2D Sidewall Density Gamma Probe
Description
The Sidewall Density Gamma Probe is a highly adaptable wireline instrument suitable for a broad range of logging operations. It measures various parameters, including:
•
Natural Gamma Radiation
•
Spontaneous Potential (SP)
•
Laterolog-3 Resistivity
•
Short-Spaced Density (SSD)
•
Long-Spaced Density (LSD)
•
Compensated Density (Dual Density)
This tool is specifically engineered for use in boreholes with diameters ranging from 50 to 300 mm. Equipped with dual detectors and high-resolution capabilities, it delivers precise near and far density measurements. Advanced stand-off compensation algorithms transform these readings into accurate compensated density data, ensuring reliable results even in challenging borehole conditions such as rugosity or fractures.
Operating Conditions
•
Cased Holes: Suitable for cased environments.
•
Borehole Fluids: Compatible with water or mud-based fluids.
Features & Benefits
1.
Enhanced Accuracy in Challenging Conditions: Utilizing sophisticated compensation algorithms, this tool delivers precise density measurements even in boreholes with rugosity and fractures.
2.
Real-Time High-Resolution Density Measurement: Provides improved resolution for thin beds, ensuring accurate real-time quantitative density data.
3.
User-Friendly Calibration: Simplifies calibration with standard Nylon and Aluminum blocks, making setup straightforward and efficient.
Applications
•
Density Porosity Analysis: Ideal for assessing porosity through density measurements.
•
In-Situ Quantitative Density Evaluation: Offers detailed, on-site density assessments.
•
Petrophysical Property Assessment: Essential for evaluating petrophysical characteristics of formations.
•
Coal Quality and Boundaries Definition: Aids in determining coal quality and delineating boundaries accurately.
•
Borehole Volume Measurement: Utilizes caliper data to measure borehole volume effectively.
