DRILLING
The recording of drilling parameters (or instant logs) consists of measuring and recording one or more physical quantities during drilling depending on the depth, the variations of which depend on the terrain encountered: forward speed, torque, water pressure...
These lithological parameters are supplemented by parameters that describe the drilling behavior: thrust, rotational speed of the rods...
Parameters
On-site instrumentation measures and records in a simple, reliable and precise way:
- Depth
- Moving speed
- Rotation speed
- Rotation torque
- Pressure on the tool
- Retain pressure
- Pressure and flow rate of the injection fluid
- Inclination X and Y
- Reflected vibration
Devices
Devices suitable for measuring and recording parameters for drilling:
- ADN
- DIALOG MX4
- BAP 160
- DEFI
Sensors
The recording of the various parameters is ensured by specific sensors:
- F82 and D90 for depth
- VR28I for rotation speed
- C16 400 and C16 50 for thrust, injection, retain and torque pressures
- IGH1620 for inclination
- V16AF50 for vibration
- EDH for flow rate and air pressure or injection fluid
Controls
Lifting
Rotation
