What should be paid attention to when using core drilling rig?

 Core drilling rig can guarantee the quality and efficiency of drilling in the actual drilling process. Different formations have different requirements, and the depth of drilling is not the same. This requires drillers to adjust the performance of the core drilling machine reasonably according to different design requirements when using the core drilling machine. In the actual use of core drilling machine, what should be paid attention to?

1. The operators of core drilling rig must be certified, and the drilling team members should be professionally trained.

2. After the core drilling equipment enters the construction site, it should be tested and run to record and observe whether the drilling rig is operating normally. If there is any abnormality, it must be debugged properly before normal construction.

3. Develop detailed drilling regulations according to the rock formations of the construction site, that is, select diamond drill bits with reasonable hardness, reasonable thickness geological pipes and related accessories.

4. The drill bit must make a detailed record report during the drilling process, analyze and report the corresponding geological conditions according to the core and actual drilling parameters.

5. Do not reverse or raise the drill pipe if the design elevation is not reached. If there is a special situation that needs to reverse or raise the drill pipe, the drill pipe should be lifted to the surface, the drill valve should be re-opened and closed, and the operator should strictly control the descending speed of the threaded drill. And rotation speed

6. Every time the core is taken out, carefully check the actual conditions of the geological casing (core tube) and drill pipe before running the drilling tool into the borehole to see if there is any bending or cracking.

7. During the drilling process of the drill bit, always pay attention to the downward situation of the drill pipe. If there is shaking or slow footage, it is necessary to judge whether there is a drilling accident in the hole according to the circulation of the flushing fluid.

8. After finishing the hole, the drilling tool must be approved by the person in charge of the construction site before the drilling tool can be lifted to the ground for measurement.

With the continuous development of the metal processing industry, the functions and torque of core drilling equipment are increasing, and the requirements for core drilling rig operators are getting higher and higher. Drilling crews can only be certified if they are proficient in professional skills. Be on duty, and always pay attention to the above precautions in actual operation, especially when drilling abnormalities, be careful to avoid major drilling accidents.
