Rotary Drilling Rig in The Construction Stuck How To Do

During the construction of rotary drilling rig, sticking is a troublesome problem, it will not only delay the construction progress, but also may cause damage to the equipment. Once stuck drilling is encountered, how to solve it quickly and effectively has become an important challenge faced by construction personnel. The following is to introduce the methods to deal with the stuck drilling situation in the construction.

1. Analyze the reasons for stuck drilling: First of all, calmly judge the reasons for stuck drilling. It may be complicated geology, such as lonely stone, hard interlayer, or accumulation of drilling slag due to improper operation, too fast drilling speed or poor mud performance. The right judgment is the right medicine.

2. Try to reverse the drilling tool: If the drilling is not serious, carefully try to reverse the power head. Apply torque slowly to see if you can loosen the drill. During the process, pay close attention to the reaction of the equipment to avoid the forced torsion of the drill pipe fracture.

3. Clean up drilling slag cycle: stuck drilling may be blocked by too much drilling slag. Through the mud circulation system, increase the mud discharge and wash the drilling slag in the hole. The accumulated drilling slag is taken out, the extrusion pressure on the drill is reduced, and the activity space of the drill is increased.

4. Up and down drilling tool: using the lifting system of the drilling rig to lift and pull the drilling tool up and down in a small amplitude. With the power of lifting, with the gravity of the drill tool itself, try to shake the stuck part, but the lifting force should be controlled well to prevent damage to the drill pipe.

5. Assistance with auxiliary tools: auxiliary tools such as jacks can be used. Under the premise of ensuring safety, apply additional force to the drill to help it out of the stuck point. Precise positioning is required during operation to avoid secondary damage to the rig and drill tool.

6. Seek professional support: If the above methods cannot be solved, contact the professional maintenance team in time. They have extensive experience and specialized equipment to solve stuck drilling problems through more complex technical means, such as underwater cutting.

Conclusion: Facing the sticking problem in the construction of rotary drilling rig, the construction personnel should keep calm, analyze the cause quickly, and take appropriate measures. From simple operational adjustments to the use of expertise, every step is critical. Timely and effective treatment of stuck drill can ensure smooth construction, reduce economic losses, and ensure that the project is completed on time.
