Ferromagnetic slim inclinometer IFM-42

 
The tool has the following modifications by max operating temperature Tmax and upper value of borehole hydrostatic pressure Pmax
  by temperature: 120°C,
  by pressure: 80 MPa.
Designed for continuous measurement of azimuth, vertical deviation angle and tool rotation angle for the purpose of well path design.

Used for open hole logging including azimuth, vertical deviation angle and tool rotation angle measurement and also for cased hole logging including vertical deviation angle measurement; the tool operates with a three-conductor carrying logging cable up to 5000m long and log recorders that provide for command transfer and data receipt in “Manchester-2” code.

Applications:
 determination of true depths of productive formations occurrence;
 borehole axis direction control while drilling.
