Introduction
Standard Evolution and Scope of Application
SY/T 5066-2020 replaces the 2008 version of the standard, adding five new technical parameters such as pressure-controlled test valve, and clearly applies to 105MPa high-pressure conditions and 260℃ high-temperature environments. The standard covers the design and manufacturing requirements of three types of formation testers: mechanical, pressure-controlled, and electric.
Core parameter system
| Parameter type | 2008 version | 2020 version new content |
|---|---|---|
| Working pressure | 35-105MPa | Increase 140MPa level |
| Temperature level | Class 3 | Add 260℃ (Class V) |
| Anti-H₂S requirements | Basic provisions | Clear material zoning selection |
Key technology upgrade
Safety design system
The standard introduces a three-level safety factor (2.0/1.5/1.25) for the first time, requiring a 2.0 factor for key well control components, which is 33% higher than the 2008 version. The modified Von Mises criterion is used in the calculation of equivalent stress, and formula (1) limits the maximum allowable stress value.
Materials and surface treatment
- H₂S-proof materials must comply with GB/T 20972.1-3 Level 3 standard
- Dynamic sealing surface hardness requirements: chemical nickel plating 60-69HRC, hard chrome plating 66-70HRC
- Newly added 38CrMoAl plasma nitriding process, surface hardness＞900HV5
Test acceptance system
| Test type | Test pressure | Acceptance index |
|---|---|---|
| Pressure control valve seal | 27.5MPa | No leakage for 3h |
| Rupture disc circulation valve | 17.5±0.7MPa | Shear pin average 43MPa |
| Hydraulic jar | 178-400kN | 10 continuous triggers |
Implementation suggestions
Selection guide
Example: DC127YT-105C means 127mm pressure-controlled full-bore tester, 105MPa working pressure, suitable for 149-204℃ working conditions.
Main points for quality control
- Ultrasonic testing is subject to acceptance according to NB/T 47013.3 Level I
- Nitrogen purity ≥99.99% (GB/T 3864)
- Trapezoidal threads require 100% magnetic particle testing
