Introduction
1. Background of standard formulation and analysis of technological evolution
With the deepening of global marine energy development, the role of offshore mobile drilling platforms in oil and gas exploration and development is becoming increasingly important. This standard aims to standardize the drilling system configuration and technical requirements of offshore mobile drilling platforms to ensure the safety and efficiency of drilling operations. This standard combines advanced domestic and foreign technologies and experiences, and especially proposes specific recommended configurations and technical parameters for the different needs of shallow and deep water drilling.
2. Comparison of shallow water drilling system and deep water drilling system framework
| Project dimensions | Shallow water drilling system | Deep water drilling system |
|---|---|---|
| Operating water depth range | ≤165 meters | ＞165 meters |
| Upper limit of drilling depth | 9,144 meters (30,000 feet) | Up to 15,250 meters (50,000 feet) |
| Key system configuration | Recommended tower derrick, single blowout preventer, 4 sets of gates | Dual hydraulic cylinder lifting derrick, double blowout preventer, 7-8 sets of gates |
3. Interpretation of the core technical requirements of the standard
Drilling system includes key parts such as lifting system, rotation system, and pipe string automation handling system. Taking the lifting system as an example, shallow water drilling platforms usually use winch lifting, while deep water drilling platforms use more hydraulic cylinder lifting to adapt to greater operating water depths and higher hook load requirements.
4. Implementation recommendations and best practices
Case study: Selection of deepwater drilling platforms
- Select a suitable rise pipe system to ensure that it is compatible with the BOP size (refer to Table 1).
- In high-pressure mud environments, it is recommended to use a high-pressure mud pump with a wide-band AC variable frequency drive to improve system stability and efficiency.
- The software of the drilling control system should pass a third-party security assessment, and interfaces with third-party equipment should be reserved to ensure inter-system collaboration.
