Abstract
A system for monitoring a bit condition in a drilling operation comprises a processor unit and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining signals representative of at least vibrations of a drilling mast having at least one bit during a drilling operation; interpreting the signals into vibration values; continuously monitoring the vibration values in real time; and assessing and outputting a condition of the bit as a function of the continuous monitoring of the vibration values.
Claims18
A system for monitoring a bit condition in a drilling operation, the system comprising:
- a processor unit;
- and
- a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for:
- obtaining signals obtained from sensors directly on a drilling mast, the signals representative of at least vibrations of the drilling mast having at least one bit during a drilling operation;
- interpreting the signals into vibration values;
- continuously monitoring the vibration values and a current of a motor of the drilling mast in real time;
- and
- assessing and outputting a condition of the bit as a function of the continuous monitoring of the vibration values, the assessing including confirming the bit condition using the current of the motor.
A system for monitoring a bit condition in a drilling operation, comprising:
- sensors adapted to be positioned directly on a drilling mast having at least one bit to produce signals representative of at least vibrations during a drilling operation;
- a signal processing unit for interpreting the signals into vibration values;
- and
- a condition monitoring module for monitoring the vibration values and a current of a motor of the drilling mast in real time, for assessing and outputting a condition of the bit, and for confirming the bit condition using the current of the motor.
