Drill pipe is a critical component in contemporary drilling operations, vital for ensuring the safety of personnel underground and fulfilling the demands of the drilling process. This article outlines the proper usage methods for drill pipe and important considerations during its operation.

 

Methods of Using Drill Pipe

1. Selection of Drill Pipe:

- Choose drill pipes based on their material and type according to the intended use;

- Ensure the drill pipe's specifications and length are adequate for the required drilling depth;

- Inspect the drill pipe for a smooth, durable surface and check for any significant damage like bruises or cracks.

 

2. Assembly of Drill Pipe:

- Assemble the drill pipes to match the specified length and diameter, avoiding any that are excessively long or short;

- Ensure that connections between drill pipes are secure, tight, and able to rotate freely;

- Apply lubricant or grease to enhance the drill pipe’s longevity;

- Assemble the drill pipe incrementally, according to the depth of the hole, to prevent breakage or jamming during drilling.

 

3. Usage of Drill Pipe:

- Select the correct drill bit for the hole diameter and the hardness of the rock;

- Wear appropriate safety gear such as helmets, safety belts, and protective footwear to protect against debris;

- Monitor the rotation direction to ensure the drill pipe and bit are synchronized, preventing twisting or damage;

- Avoid overloading the drill pipe to maintain its integrity and service life.

 

4. Maintenance of Drill Pipe:

- Replace drill pipes promptly if there is noticeable damage or wear;

- Clean off any dust or dirt after use, and apply lubricant or grease;

- Store unused drill pipes in a dry, ventilated area and treat with anti-rust oil to prevent corrosion.

Precautions When Using Drill Pipe

1. Conduct regular inspections of the drill pipe to prevent potential issues;

2. Select drill pipes that are appropriate for the specific drilling conditions and well characteristics;

3. Adhere strictly to the specifications and precision requirements for joint connections to avoid issues like loosening or detachment;

4. Manage the speed of lifting and lowering the drill pipe carefully to reduce wear and tear;

5. Ensure that auxiliary tools used on the drill pipe, such as tongs and wrenches, comply with safety standards and operational requirements to prevent hazards like tool slippage.
