Introduction
Core changes in the standard revision
| Key dimensions | 2014 version | 2024 version | Technical impact |
|---|---|---|---|
| Organizational structure | 7 working groups | 8 working groups (newly added safety and environmental protection group) | Strengthen the HSE management system |
| Operation classification | No clear distinction | Added dual paths of fire operation and non-fire operation | Improve adaptability to high sulfur conditions |
| Fire-fighting technology | 4 methods | 5 methods (new rescue well fire-fighting method) | Expanded ultra-high pressure well disposal methods |
Analysis of key technical points
1. Innovative specifications for fire-related operations
For the first time, the standard clearly defines the three-level cooling system for the fire-related operations scenario: wellhead cooling (level one) → equipment protection (level two) → personnel protection (level three), and requires that when special processes such as hydraulic sandblasting and cutting are used, the ambient temperature must be controlled below 120°C.
2. Well Killing Decision Matrix
| Operating Condition Characteristics | Recommended Method | Critical Parameters |
|---|---|---|
| Wellhead Pressure＞70% Rated Value | Push Method | Pump Pressure≤35MPa |
| Casing Heat Damage | Replacement Method | Density Difference≤0.3g/cm³ |
| Serious Reservoir Deficit | Well Seal/Production | Lose-Away Volume＞10m³/min |
Implementation Suggestions
High-sulfur Blowout Case
When the H₂S concentration in a shale gas well reaches 1500ppm, the fire operation mode should be given priority: ① Establish a three-level water curtain isolation zone → ② Use ignition tubes to concentrate the flame → ③ Remote manipulators to remove the damaged wellhead → ④ Install acid-resistant rescue casing heads, and continuous gas monitoring must be maintained throughout the process.
Standard Implementation Roadmap
- Plan initiation phase: Complete the establishment of 8 professional teams within 1 hour
- Risk assessment phase: Flame temperature, wellhead deformation, and toxic gas diffusion model must be tested
- Scheme decision phase: Select the operation path based on the wellhead integrity index
- Post-processing phase: Establish a 72-hour re-ignition monitoring mechanism
