Introduction
Analysis of the core content of the standard
| Technical dimension | SY/T 5699-2010 | SY/T 5699-2016 | Technical improvement points |
|---|---|---|---|
| Chemical composition | S/P≤0.030% | S/P≤0.020% | Material purity requirement increased by 40% |
| Structural type | Single structure | New internal thread structure | Adapt to complex working conditions |
| Testing standards | Quote SY/T 5144 | Updated testing methods | Aligned with the latest international standards |
Detailed explanation of key technical requirements
1. Material specifications
The standard stipulates that lifting nipples must be made of alloy steel, with sulfur and phosphorus content tightened from ≤0.030% in the 2010 version to ≤0.020%. This modification increases the material's resistance to hydrogen-induced cracking (HIC) by about 35%, making it particularly suitable for sulfur-containing oil and gas field conditions.
2. Structural Innovation
The 2016 version adds the internal thread structure at the lifting end design. The technical parameters of the two structural types are compared as follows:
| Parameters | Structure without internal thread | Structure with internal thread |
|---|---|---|
| Applicable elevator type | 18"/90° | 18"/90° |
| Maximum lifting force | 1500kN | 1800kN |
| Typical applications | Conventional drilling | Deep Well/Ultra-deep Well |
Implementation and Application Suggestions
Tarim Oilfield Application Case
In the 8000m ultra-deep well project, the new version of the TSDJ127-6′REG lifting nipple was used. Its improved thread structure reduced the connection failure accident rate by 62% year-on-year. Key implementation points:
- Strictly control the sulfur and phosphorus content of materials according to Table 3
- -20℃ low temperature impact test must meet the standard
- Thread surface roughness Ra≤3.2μm
Standard evolution analysis
Three major technological leaps from the 1995 version to the 2016 version:
- First generation (1995): Establishment of basic size series
- Second generation (2010): Introduction of non-destructive testing requirements
- Third generation (2016): Improved material purity + structural innovation
