Product Description

Borehole Logging Geophysical Land Products Downhole Log Survey Geophysical Formation Evaluation Groundwater Hydrogeology Logging Equipment 300m 500m 800m 1000m
Geophysical borehole logging techniques are essential tools in understanding subsurface formations and groundwater hydrogeology. These techniques can provide detailed data on various parameters such as porosity, permeability, mineralogy, water quality, and salinity distribution. They are particularly useful in coastal aquifers to identify geological layering and characterize salinity distribution.

Advanced borehole geophysical logging methods can offer fine-scale data not easily obtainable through traditional means, providing insights into porosity, hydraulic conductivity, and aquifer mineral composition. These techniques, such as neutron-gamma ray spectroscopy and microresistivity imaging, are especially valuable for detailed hydrogeological investigations.

Application: 
combined with the analysis and interpretation results of the above-mentioned measured physical parameters, comprehensive comparative analysis,
evaluation of the fracture degree of the rock within the hole at the acoustic velocity,
comprehensive apparent resistivity,
natural potential,
well temperature,
well fluid Logging parameters such as resistivity (salting) are used for groundwater evaluation,
and comprehensive interpretation
and evaluation of borehole anomalies are performed.
High-density survey anomalies have been fully verified by drilling and logging.



Features:
study of water-bearing strata and hydrological parameters has high accuracy,
and has the advantages of convenience, low consumption, etc.,
and can achieve twice the result with half the effort.
The application effect on hydrological environmental geological survey, engineering quality inspection, geological environment monitoring, etc. is very obvious, and plays a greater role in opening up the geological market.
