Introduction
Analysis of the core content of the standard
| Technical elements | Requirements of the 2014 version | New regulations of the 2021 version | Technological evolution |
|---|---|---|---|
| Classification system | 3 basic types | 4 types + auxiliary function types | New expansion type (type D) and containment type (type XQ) |
| Anti-corrosion requirements | H2S protection | H2S/CO2 double protection (type CS) | Adapt to the development needs of high-acid gas fields |
| Performance parameters | 5 core indicators | 8 extended indicators | Increase anti-torsion capacity, reverse locking force, etc. |
Detailed explanation of key technical requirements
1. Liner hanger classification system
The 2021 version divides liner hangers into four basic types:
- Hydraulic type (YY type): Drive slips through hydraulic pressure below 2MPa
- Mechanical type (J type): Use lifting/rotating mechanical action
- Dual-acting type (D type): Hydraulic and mechanical compound drive
- Double-acting type (D type): Hydraulic and mechanical compound drive
- Expansion type (P type): radial plastic deformation technology
2. Comparison of core performance indicators
Typical specifications of XG245×178-YFS type hanger:
- Sealing ability: 35MPa (increased by 40%)
- Suspension load: 2000kN (increased by 25%)
- Torsion resistance: 50kN·m (new indicator)
Implementation suggestions
Selection decision matrix
| Working conditions | Recommended type | Technical basis |
|---|---|---|
| Highly deviated wells/horizontal wells | Rotational containment type (FXQ) | Standard 5.2.13 reverse locking force requirements |
| Sulfur-containing gas fields | CS double protection type | Standard 6.1.6 Corrosion test specifications |
