Tension,Borehole Temperature and Mud Resistivity Sub

Brief Introduction:

TTMR provides cable head tension, current borehole temperature, and drilling fluid resistivity. The cartridge consists of a sonde assembly and an electronics section.

When the force of the instrument changes, the strain resistance of the tension probe changes accordingly. By measuring the strain resistance, the state of the logging tool when it is stuck and when it is stuck can be judged.

When the temperature changes, the resistance value of platinum resistance changes linearly with the temperature.

The instrument transmits a constant current signal into the drilling fluid to measure the potential at two fixed points in the return circuit and obtain the resistivity of the drilling fluid.
