Features & Advantages

High-Capacity Lifting System
This advanced Well Servicing Rig features a robust lifting system with 675KN maximum static hook load capacity, designed to handle heavy tubing strings and downhole equipment. The precision-controlled hook speed range (0.11-1.15 m/s) allows for delicate operation during critical well intervention tasks while maintaining efficiency during routine operations. The system incorporates automatic safety brakes and load monitoring systems to ensure secure operation under all loading conditions.

• Operational Advantage: Enables handling of complete tubing strings and heavy downhole equipment, reducing the need for additional support equipment and increasing operational efficiency during workover operations.

Versatile Derrick Configuration
The Well Maintenance Truck offers three derrick height options (18m, 21m, 23m) to accommodate various well depths and operational requirements. The telescopic mast design provides optimal vertical clearance while maintaining structural integrity during lifting operations. The derrick incorporates automatic locking systems and safety interlocks to ensure secure operation at full extension and maximum load capacity.

• Operational Advantage: Flexibility to configure the equipment for different well configurations and operational requirements, making it suitable for both shallow well maintenance and deep well workover operations.

Robust Chassis Platform
The heavy-duty 6×4 chassis with 300×80×(8+5)mm frame provides exceptional stability and load-bearing capacity for workover operations. The optimized weight distribution and reinforced suspension system (10-front/12-rear leaf springs) ensure operational stability even when handling maximum hook loads. The 5.571 axle ratio provides optimal torque conversion for both mobility and stationary operations.

• Operational Advantage: Enhanced stability during critical lifting operations reduces safety risks and improves operational precision, while the robust construction ensures reliability in harsh oilfield environments.

Advanced Control Systems
The Oilfield Service Rig features comprehensive control systems including load monitoring, position sensing, and automated safety systems. The remote control capability allows operators to manage operations from optimal viewing positions, while the integrated data logging system records all operational parameters for analysis and reporting.

• Operational Advantage: Improves operational safety and precision while reducing operator fatigue during extended operations, ensuring consistent performance and accurate documentation of all workover activities.

5. Frequently Asked Questions (FAQ)

Q1: What types of well depths can this equipment handle?
A: This Oilfield Service Rig is designed to handle a wide range of well depths, from shallow wells to medium-depth applications. The 23m derrick configuration provides sufficient vertical clearance for handling standard tubing doubles, while the 675KN hook load capacity enables operation in wells requiring significant pulling force. The specific depth capability depends on factors including tubing weight, well conditions, and operational requirements.

Q2: What safety features are included in the lifting system?
A: The Well Servicing Rig incorporates multiple safety features including automatic braking systems, load moment indicators, derrick angle sensors, and emergency shutdown systems. All safety systems are designed to meet international oilfield safety standards and include redundant protection mechanisms to ensure operational safety.

Q3: Can the equipment be operated in remote locations?
A: Yes, this Well Maintenance Truck is designed for operation in remote oilfield locations. The 6×4 drive configuration provides good mobility on unprepared surfaces, while the comprehensive onboard systems include all necessary components for independent operation. The equipment is designed for easy maintenance with readily available components.

Q4: What training is provided for operators?
A: Hubei Tri-Ring provides comprehensive operator training programs covering equipment operation, safety procedures, and basic maintenance. The training includes both classroom instruction and hands-on operation under supervision. We recommend that all operators complete certified well intervention training programs in addition to equipment-specific training.

Q5: How does the emission compliance affect operation in different regions?
A: The availability of multiple emission standards (Euro II through Euro VI) ensures that the Oilfield Service Rig can be configured for operation in virtually any region worldwide. For operations in areas with strict emission controls, we recommend the Euro VI configuration with advanced aftertreatment systems. This flexibility allows operators to meet local regulatory requirements while maintaining operational performance.
