Thermometer-manometer (ТD)

ТД

The tool has the following modifications by max operating temperature T max and upper value of borehole hydrostatic pressure Pmax :
  by temperature: 120, 150, 175, 200 °С,
  by pressure: 80, 100, 120, 140 МPа.

Designed for borehole temperature and pressure measurement.

Used for logging of open and cased oil and gas wells filled with any mud; the tool operates with a three-conductor carrying logging cable up to 7000m long and log recorders that provide for command transfer and data receipt in “Manchester-2” code.

Applications:
 rocks temperature and geothermal gradient evaluation.
