Introduction
Analysis of the key points of standard update
| Revision dimensions | 2014 version | 2020 version |
|---|---|---|
| Standard name | On-site installation and inspection of oil drilling rigs | On-site installation and inspection of oil and gas drilling and production equipment drilling rigs |
| Wellsite foundation requirements | Foundation form is not detailed | New clauses on special requirements for foundation bearing strength |
| Equipment classification | 7 types of systems | Expanded to 12 types of systems (newly added string automation, etc.) |
Core installation technical requirements
1. Derrick installation specifications
During the lifting process of the self-elevating derrick, when the angle reaches 75°~80°, the speed must be reduced for buffering. After the derrick is in place, the deviation between the center of the crane and the center of the turntable should be ≤20mm. Key control points:
- Stop and check at a trial lifting height of 100-200mm
- Operation is prohibited when wind speed exceeds Level 5 (8.0m/s)
- Double-lift drilling rigs require secondary alignment
2. Anti-collision system upgrade
The 2020 version clearly requires the configuration of two independent anti-collision systems, including:
Over-roll valve type: Braking is completed within 3 seconds after the lever is triggered
Digital anti-collision: High/low limit deceleration test is required
Typical equipment installation parameters
| Equipment type | Key indicators | Allowance Deviation |
|---|---|---|
| Drive Sprocket | Coplanarity | ≤0.045 times pitch |
| Pulley | V-groove Coplanarity | ≤1/3 wheel width |
| Hydraulic Disc Brake | Brake Disc Runout | ≤0.3mm |
Implementation Suggestions
- Foundation Pre-inspection: The base of the frozen soil area needs to be 250mm below the freezing line
- Digital Management: It is recommended to use an electronic inspection record system
- Staff Training: Focus on training on string automation system operation
