What are the operating skills of directional drilling rigs?
Jul 24, 2024| 1. Preparation before construction: fully understand the geological conditions of the construction site, the distribution of underground pipelines and other information, and plan the drilling route. Check whether the various performance and equipment of the drilling rig are normal, and ensure that the drill bit, drill rod and other components are intact.
2. Accurate measurement and positioning: Use measuring instruments to accurately determine the starting and ending positions of drilling, as well as the angle and depth of drilling.
3. Slow start: When starting the drilling rig, increase the speed and torque slowly to avoid sudden high-load start-up and impact on the equipment.
4. Control the drilling speed: According to the geological conditions and drilling requirements, adjust the drilling speed reasonably. When encountering hard formations, slow down the speed appropriately to prevent excessive wear or damage to the drill bit.
5. Pay attention to torque and thrust: Closely monitor the values of torque and thrust to avoid exceeding the rated parameters of the equipment and preventing equipment overload.
6. Timely slag removal: During the drilling process, drill cuttings and mud should be discharged in time to keep the borehole unobstructed and avoid blockage and increased resistance.
7. Guidance control: Use the guidance system to adjust the drilling direction in real time to ensure that the drilling is carried out according to the predetermined trajectory.
8. Drill rod connection: When connecting the drill rod, ensure that the connection is firm to prevent it from falling off during the drilling process.
9. Shutdown specification: When shutting down, the speed and torque should be reduced first, and then the engine or power supply should be turned off to avoid damage to the equipment caused by sudden shutdown.
10. Cleaning after construction: After completing the construction, clean the dirt and debris on the equipment and perform maintenance on the equipment.
