3. Functional Description

3.1 Core Functional Advantages

Each spare part is engineered to fulfill the specific functional requirements of RG Petro rigs, supporting critical operations such as drill string hoisting, rotation, well control (drilling rigs), and well workover, completion, or maintenance (workover rigs). Key functions include load-bearing stability for structural parts (e.g., frames, shafts) to withstand high operational loads, smooth power transmission for rotating components (e.g., bearings, gears) to ensure consistent rig performance, reliable sealing for hydraulic and oil systems to prevent leakage, and precise positioning for guiding parts to maintain operational accuracy.

3.2 Model-Specific Adaptability

Spare parts are customized for different RG Petro models: heavy-duty ZJ70/ZJ90 series drilling rig parts feature enhanced load-bearing capacity to support deep drilling operations; compact XJ/SXJ series workover rig parts prioritize portability and quick installation for on-site flexibility; MZJ/HZJ series parts are optimized for medium-load operations, balancing durability and cost-effectiveness. All parts integrate with the rig’s existing systems seamlessly, avoiding compatibility issues that could disrupt operations.

4. Structural Features

4.1 Material Selection

Key components adopt high-strength alloy steel (40Cr, 20CrMnTi), wear-resistant cast iron, and precision bearings (SKF-equivalent grade), treated with quenching, tempering, or carburizing processes to enhance hardness, toughness, and fatigue life. Sealing elements use nitrile rubber (for general conditions) and fluorine rubber (for high-temperature, high-pressure, or corrosive environments) to ensure long-term sealing performance. Fasteners comply with GB standards (GB5783, GB93) and are made of high-tensile steel, ensuring secure connections under extreme operational loads.

4.2 Design Highlights

Parts adopt RG Petro’s original modular and standardized design, optimizing stress distribution to avoid stress concentration during high-load operations. Structural components feature reinforced rib designs to enhance load-bearing capacity; rotating parts are precision-machined to reduce friction and noise; hydraulic components are designed with anti-clogging structures to adapt to harsh on-site conditions. The standardized interface design facilitates quick installation and replacement, reducing maintenance time and improving operational efficiency.

5. Applicable Working Conditions

Our spare parts are suitable for the diverse working conditions of RG Petro drilling and workover rigs, including onshore oil and gas fields, shale gas exploration sites, coalbed methane wells, and geothermal drilling projects. They can adapt to extreme environmental conditions such as high temperatures (up to 65℃), low temperatures (down to -45℃), high humidity, dust, saline-alkali soil, and strong vibration. Whether in desert, mountain, coastal, or plain areas, the parts maintain stable performance, meeting the long-term high-load operation requirements of drilling rigs and the flexible, frequent-movement needs of workover rigs.

6. Maintenance & Service Recommendations

6.1 Routine Maintenance

1. Regular Inspection: Conduct weekly inspections of key parts, including fastener tightness, bearing rotation smoothness, seal integrity, and hydraulic system pressure. Check for abnormal noise, oil leakage, or component deformation, and address potential issues promptly. 2. Lubrication Management: Inject API-compliant lubricating oil/grease into rotating parts (bearings, gears) every 120-150 working hours; use high-temperature anti-wear grease for components exposed to high heat, and ensure lubrication channels are unclogged. 3. Cleaning Maintenance: Regularly remove drilling fluid residues, dust, and debris from parts surfaces, especially hydraulic valves and seals, to prevent corrosion and blockage.

6.2 Replacement & Installation Guidelines

1. Replacement Timing: Replace parts according to RG Petro’s original maintenance manual or when faults occur (e.g., bearing wear exceeding 0.5mm, seal leakage, gear tooth damage, or fastener deformation). 2. Installation Requirements: Use professional tools, follow RG Petro’s installation specifications, and torque fasteners to standard values. Ensure precise alignment of rotating parts (e.g., gears, shafts) to avoid premature wear. 3. Post-Replacement Testing: Conduct a test run after replacement to verify normal operation, checking for abnormal vibration, noise, or performance degradation.

6.3 Storage & Preservation

Store spare parts in a dry, ventilated, and clean warehouse, avoiding direct sunlight, rain, and chemical contamination. Classify parts by model and type, and label them clearly. Precision components (bearings, seals) should be stored in sealed packaging to prevent dust and moisture; structural parts should be placed horizontally to avoid deformation. For long-term storage, apply anti-rust oil to metal parts and inspect quarterly for rust or damage.

7. On-Site Fault Repair Cases

Case 1: ZJ40/2250CZ Drilling Rig Bearing Damage Causing Abnormal Noise

Fault Phenomenon: A ZJ40/2250CZ drilling rig experienced loud abnormal noise and overheating in the rotary table during operation, affecting drill string rotation stability. Diagnosis: Precision bearing wear and contamination due to insufficient lubrication and drilling fluid leakage, leading to raceway damage. Solution: Replaced the bearing with an OEM-compatible, SKF-equivalent part, cleaned the bearing housing, and refilled with API 7K-compliant high-temperature lubricating oil. Result: Abnormal noise and overheating were eliminated, rotary table operation returned to normal, and bearing service life was extended by 50%.

Case 2: XJ900(XJ60) Workover Rig Hydraulic Seal Leakage

Fault Phenomenon: An XJ900(XJ60) workover rig had persistent hydraulic fluid leakage from the lifting system, reducing operational pressure and affecting lifting performance. Diagnosis: Fluorine rubber seal aging and damage due to long-term exposure to high temperatures and hydraulic fluid contamination, failing to maintain sealing integrity.Solution: Replaced the seal with a high-temperature, corrosion-resistant OEM-compatible part, cleaned the seal groove, and filtered the hydraulic system to remove contaminants. Result: Hydraulic leakage stopped, system pressure stabilized, and the workover rig resumed normal lifting operations.

Case 3: ZJ30/1700DT Drilling Rig Fastener Loosening & Structural Vibration

Fault Phenomenon: A ZJ30/1700DT drilling rig exhibited excessive vibration during hoisting, with visible fastener loosening in the frame structure. Diagnosis: High operational vibration caused standard fasteners to loosen, and some fasteners had fatigue deformation, reducing structural stability.Solution: Replaced deformed fasteners with high-tensile, anti-loosening OEM-compatible parts, retightened all frame fasteners to standard torque, and installed vibration dampeners. Result: Rig vibration was significantly reduced, structural stability was restored, and the risk of component damage from vibration was eliminated.

Case 4: HXJ180DB Workover Rig Gear Wear & Power Transmission Failure

Fault Phenomenon: An HXJ180DB workover rig had intermittent power transmission failure, with abnormal noise from the gearbox during operation. Diagnosis: Gear tooth wear and pitting due to insufficient lubrication and misalignment, leading to unstable power transmission. Solution: Replaced the worn gear with an OEM-compatible, precision-machined part, adjusted gear alignment, and refilled with anti-wear lubricating oil. Result: Power transmission became stable, abnormal noise was eliminated, and the workover rig’s operational efficiency was fully restored.
