With 20 years of drilling experience, I've handled over a hundred cases of troubleshooting stuck drill pipe. Today, I'll summarize the most practical methods for troubleshooting stuck drill pipe into five steps that even beginners can quickly master.

1. Immediate Shutdown and Diagnosis

The first step in troubleshooting stuck drill pipe is to stop drilling immediately:

(1) Halt all rotation and feed movements

(2) Record the stuck depth, drilling pressure, and RPM

(3) Identify the sticking type (cuttings accumulation/cave-in/mechanical)

This troubleshooting stuck drill pipe action prevents secondary damage

2. Attempt to Free the Pipe

Basic techniques for troubleshooting stuck drill pipe:

(1) Alternate rotation (≤30° each direction)

(2) Apply gentle lifting/lowering (≤80% rated pull force)

(3) Continue for 10-15 minutes to check for loosening

Warning: Never use excessive force during this troubleshooting stuck drill pipe phase

3. Flushing Solutions

For cuttings-induced troubleshooting stuck drill pipe:

(1) Prepare high-lubricity mud (add 0.3% lubricant)

(2) Use pulse flushing (3 seconds on/2 seconds off)

(3) Gradually increase pressure (5MPa→15MPa in stages)

This troubleshooting stuck drill pipe method has 60% success rate

4. Jarring Techniques

Persistent troubleshooting stuck drill pipe requires tools:

(1) Hydraulic jars: Install at top of drill string for downward impacts

(2) Frequency control: 15-20 impacts per minute

(3) Force adjustment: Start at 50% rated impact energy

Note: This troubleshooting stuck drill pipe method needs specialized equipment

5. Last Resort: Pipe Cutting

When all troubleshooting stuck drill pipe methods fail:

(1) Locate stuck point (with magnetic/electrical tools)

(2) Install cutter 1m above stuck point

(3) Retrieve free pipe sections (preserve samples)

This troubleshooting stuck drill pipe solution is the final option

Prevention Tips:

1. Pull out every 50m to clean hole bottom

2. Use casing in unstable formations

3. Prepare emergency kit (jars/cutters/special mud)

Remember: The keys to successful troubleshooting stuck drill pipe are speed, precision, and gentleness!
