Analysis of key technical parameters
Drilling equipment system (DES) design
derrick and base layout must meet the following requirements:
- Maximum hook load calculation: Q≥1.2×F string+500kN
- Drilling platform clearance height: H=H1+H2 (wellhead device height + bell pipe height)
- Top drive torque must meet the requirements of GB/T 31049
Modular design specifications
| Module type | Component equipment | Layout requirements |
|---|---|---|
| Drilling equipment system (DES) | Derrick, winch, top drive, etc. | Three-layer layout in the well slot area |
| Drilling support system (DSM) | Generator set, drilling pump, etc. | Symmetrically arranged in front of DES |
| Bulk tank module (P-Tank) | Benzene tank, cement tank, etc. | Main deck vertical structure |
Key points of safety design
- The selection of explosion-proof electrical equipment complies with GB/T 3836.1
- The width of the escape passage is ≥1m, and the clear height is ≥2.2m
- The blowout preventer must be closed within 30 seconds
- Equipped with two independent fire water systems
Implementation suggestions
- Prioritize the use of Z-directional performance steel to make key nodes
- The structural analysis must include loading/towage/hoisting conditions
- The voltage distortion rate of the electrical system is controlled within 5%
- The interface design reserves platform system access points
