1～4000Ωm(customize10000Ωm)JDX-2Dr Natural Gamma & Electrical Resistivity Probe

Description

The Electrical Resistivity probe measures natural gamma,gradient resistivity,normal resistivity and spontaneous potential (SP) simultaneously. Users can log resistivity profiles with different depths of investigation and gain information about permeability, porosity, water quality and geological formation properties.

Operating Conditions:Uncased；Borehole Fluid:Water or Mud

Features & Benefits

1, The probe will digitize the measured information of the stratum and transmit it to the surface to avoid the effect of the cable on the measurement data.

2, Constant power, adaptive measurement, no manual operation.

Applications

Facies changes；Quantitative geological formation properties

Identification of hydrostratigraphic units

Aquifer thickness；Water quality

Identification of hydrocarbon intervals

Detection of ore body zones；Bed boundary analysis
