Small Rotary Drilling Rig in The Construction Process, Bending Hole, Deflection How To Do

The small rotary drilling rig plays an important role in the construction, but sometimes it will encounter difficult problems such as curved hole and deflection, which not only affects the construction progress, but also may cause hidden dangers to the quality of the project. Here are some effective ways to deal with these situations.

1. Check geological conditions: detailed geological investigation before construction, if encountered uneven soft and hard strata, it is easy to lead to curved holes. Know the geological characteristics in advance and develop specific plans, such as adjusting drilling parameters.

2. Calibration equipment installation: Ensure that the small rotary drilling rig is installed horizontally and firmly. Installation is not standard, the drilling process is prone to deviation. Use tools such as levels to accurately calibrate equipment.

3. Selection of suitable drilling tools: according to different geology, select the matching drilling tools. If in hard rock layer, use carbide drill bit; The drilling tool is not suitable, easy to cause the drilling is not straight.

4. Control drilling speed: drilling speed should not be too fast, especially in complex formations. Too fast drilling speed will make the drill uneven force, resulting in bending holes and deflection.

5.timely correction operation: the construction should always monitor the drilling situation, once the deviation is found, immediately stop drilling. Correct deviation in time by backfilling clay and re-drilling.

6.Regular maintenance of equipment: regular maintenance of small rotary drilling RIGS to ensure the normal operation of equipment components. For example, check whether the drill pipe is bent, and repair or replace the faulty parts in time.

Conclusion: In the construction process of small rotary drilling rig, through careful inspection of geology, standardized installation equipment, reasonable selection of drilling tools, control of drilling speed, timely correction of deviation and regular maintenance of equipment, the problems of bending hole and deviation can be effectively solved, and the smooth construction and project quality can be guaranteed.
