Strictly Inapplicable Scenarios
1.Wells deeper than 10000m: exceeds mechanical safety margin.
2.Ultrahigh temperature wells (> 150℃): causes insulation aging and performance failure.
3.Short-radius horizontal wells and sharp dogleg wells: not suitable for extreme bending.
4.Extremely severe H₂S/CO₂ corrosion environment without special anti-corrosion treatment.
5.Ultra-high pressure environment exceeding the rated pressure grade.
