What Are The Micro-operations of A Rotary Drilling Rig

The operation of a rotary drilling rig is not merely about "digging" and "lifting". Those experienced masters can always make the construction both fast and good through some minor operations. What practical micro-operations are there exactly? This will reveal it to you.

1. Precise alignment and fine-tuning: Before starting the drilling, use the fine-tuning function of the drilling rig to move the drill pipe slightly forward, backward, left and right to ensure that the drill bit is aligned with the center point of the pile position. Even a deviation of just a few centimeters may affect the accuracy of subsequent construction.

2. Coordination of drilling pressure and rotational speed: Fine-tune the drilling pressure and rotational speed in real time according to different geological conditions. For instance, when encountering hard soil layers, appropriately increase the drilling pressure and reduce the rotational speed to allow the drill bit to cut in slowly and avoid damaging the equipment through hard biting.

3. Drill pipe verticality correction: During the drilling process, constantly monitor the drill pipe verticality instrument. If any tilt is detected, promptly fine-tune it through the hydraulic system. Only by keeping the drill pipe vertical can the quality of hole formation be guaranteed.

4. Mud performance control: By adding appropriate amounts of bentonite, cellulose and other materials, the specific gravity and viscosity of the mud can be fine-tuned. High-quality mud can effectively protect the wall and prevent hole collapse.

5. Hoist speed control: When lifting the drill bucket, fine-tune the hoist speed according to the amount of debris inside the bucket. When the construction waste is too full, slow down to prevent it from spilling and also reduce the impact on the equipment.

6. Control of rotation Angle: When transferring the drilling position, control the rotation Angle and speed of the drilling rig properly. Small angles and slow rotation can not only ensure operational safety but also reduce equipment wear.

These micro-operations of rotary drilling RIGS, though seemingly minor, have a significant impact on construction quality, equipment lifespan and operational efficiency. Mastering these micro-operation skills can enable the rotary drilling rig to achieve greater efficiency and make every drilling operation more precise, efficient and safe.
