1～2500ΩM 0～250℃ Geothermal Resistivity & Inclinometry with Platinum Resistance Sensor

The Geothermal Resistivity & Inclinometry Probe is a multi - purpose and high - efficiency combination logging instrument.Multiple parameters can be measured at the same time,Temperature,Vertex Angle,Azimuth,Laterolog-3 Resistivity Etc. Resistivity measurement with the method of focusing current, reduce the completion fluid to calculate the influence of resistivity and low resistance strata, so as to make the measurement of apparent resistivity of calculation is more close to the true resistivity of rock. The bending rate, eccentricity, horizontal displacement and vertical distance of borehole can also be calculated by measuring the Angle and azimuth.

Operating Conditions:Uncased；Borehole Fluid: Water or Mud

Features & Benefits

1. The lateral resistivity has strong stratification capability of lithologic profile and is less affected by well fluid.

2. High precision gravity acceleration sensor and high precision magnetic field sensor are adopted to improve the shock resistance and durability of the instrument.

3. The sensor adopts pt1000 platinum resistance of a small time constant and can quickly identify temperature changes in the stratum.
