Common Misunderstandings in Operating Rotary Drilling RIGS

The standardization of rotary drilling rig operation directly affects construction safety and efficiency. However, in actual operations, some common misunderstandings are often overlooked, which may lead to equipment wear and tear, project delays, and even safety accidents.

1.Neglecting pre-inspection: Skipping the inspection of key components of the equipment, such as the hydraulic system and drill pipe connection, before starting up can easily lead to mid-process failures due to component hazards, increasing maintenance costs.

2. Blind pressure drilling: Believing that the greater the pressure, the faster the drilling will be, in fact, it may cause the drill pipe to bend and the motor to overload. Especially in hard strata, excessive pressure will have the opposite effect.

3. Arbitrary slurry ratio: The slurry concentration is not adjusted according to the geological conditions. In mild cases, it may lead to the collapse of the hole wall; in severe cases, it may affect the quality of pile formation and increase the risk of rework.

4. Illegal over-depth operation: Exceeding the rated drilling depth of the equipment without authorization in pursuit of progress will increase the load on the machine body, causing deformation or even overturning of the mechanical structure.

5. Neglecting environmental adaptation: Operating on soft ground or sloping sites without reinforcing the machine body can easily cause the equipment to tilt due to ground subsidence, posing a threat to operational safety.

6. Delayed maintenance timing: Only carrying out maintenance after equipment failure while neglecting daily lubrication, filter element replacement and other maintenance will shorten the service life of the equipment and increase the probability of sudden failure.

When operating a rotary drilling rig, it is necessary to strictly follow the norms and avoid these misunderstandings. Only by attaching importance to the preliminary inspection, scientific operation, parameter adjustment as needed and timely maintenance can the construction efficiency be improved, the equipment life be prolonged and the project be smoothly advanced under the premise of ensuring safety.
