The drilling console contains the analog and digital gauges used to monitor the key parameters required for efficient drilling and effective well control. It also has four chart recorders for monitoring pit level, drill pipe, penetration rate and casing pressures.
A detailed description of the various components of the Drillers Console is as follows:
- Weight Indicator: A large-scale face indicator calibrated to 500,00 lbs. The second dial with expanded sensitivity is utilized to indicate weight-on-bit. Operator can zero set second dial.
- Weight-On-Bit: Digital readout of actual weight-on-bit.
- Rotary Torque: A circular 4″ face gauge that measures rotary torque with a scale of 0 to 1,000 amps.
- Tong Torque: A circular 4″ face gauge that measures make up or break out torque.
- Return Mud Flow: A circular 6″ face gauge that measures the return in the flow line from the well with a scale of 0 to 100%. It consists of high and low set controls with 2 visual alarm indicators, a level adjust and a power on/off switch.
- Rotary Speed (rpm): A circular 4″ gauge that measures the rotary rpm with a scale of 0 to 300 rpm.
- Mud Pump 1 (spm): A circular 4″ gauge that measures the pump stroke per minute scaled for 0 to 200 spm.
- Low Pressure Select: A Circular 4″ gauge that can be selected to measure casing pressure or drillpipe pressure, scaled at 0 to 1500 psi.
- Mud Pump 2 (spm): A circular 4″ gauge which measures the pump strokes per minute, scaled at 0 to 200 spm.
- Stroke Counter: A digital readout of total elapsed strokes with reset and run/hold control.
- Drillpipe Pressure: A circular 6″ gauge that measures drillpipe pressure. Scales are combined in psi and kg/cm². These scales are 0 to 5000 psi and 0 to 350 kg/cm².
- Mud Weight Indicator: A digital indicator that measures return mud weight.
- Casing Pressure: A circular 6″ gauge that measures casing pressure. Scales are combined in psi and kg/cm². These scale are 0 to 5,000 psi and 0 to 350 kg/cm².
- Deviation Mud Volume: A circular 6″ gauge that measures the increase or decrease in mud volume. It consists of high and low level set controls with two visual alarms.
- Mud Volume Totalizer: A circular 6″ gauge that measures the total mud in the system with a scale of 0 to 1,000. A power on/off switch and four mud tank switches are provided so the student can add or subtract mud from the system.
Note: For mud volume Totalizer to become operational, the on/off
switch must be in the “ON” position.
- Stand Tally: A digital readout that displays the total number of stands in the hole.
Note: Each stand is equal to 90 feet.
- Stand Tally Control: A one-turn control that will allow the student to decrease the number of stands in the hole.
Note: When participating in well control exercises with bit on bottom, this control must be in the fully clockwise direction to indicate bit on bottom.
- Chart Recorder: There are four two-pen chart recorders that can be used for a permanent performance record.
- Trip Tank: 4″ circular gauge that measures the total number of barrels of mud in the trip tank.
- Stripping Tank/Trip Tank: A two-position switch that allows the student to select either the stripping tank or trip tank.
- Stroke Counter: A digital readout of total pump strokes.
Note: Cement pump strokes will be read on this digital readout.
- Trip Tank Pump: A push button illuminated switch that allows the student to enter mud into the hole. This switch will become illuminated when stands are removed from the hole.
- On/Off Switch: A switch allowing the geolograph to be turned on or off.
