3. Functional Description

3.1 Core Component Functions

Each spare part fulfills critical operational roles to ensure the smooth running of CPTDC rigs: Hydraulic Disc Brakes (PSZ series) provide reliable braking force for drill string hoisting and lowering, ensuring operational safety; Swivels (SL series) enable continuous drill string rotation while maintaining well control pressure; Hooks (DG series) and Traveling Blocks (YC series)/Traveling Block & Hook Assemblies (YG series) support and lift heavy drill strings, with high load-bearing capacity; Mud Pumps (F series) circulate drilling fluid to cool the drill bit, remove cuttings, and maintain wellbore stability; Drawworks (JC series) drive drill string hoisting and lowering, with different types (SCR/DC, VFD/AC, mechanical) adapting to varying power requirements; Rotary Tables (ZP series) transmit torque to drive drill string rotation for drilling operations; Crown Blocks (TC series) guide wire ropes to distribute loads evenly during hoisting. All parts work in tandem to maintain the rig’s core operational capabilities.

3.2 Model-Specific Adaptability

Spare parts are customized to match the unique requirements of CPTDC’s diverse rig models and components: Heavy-duty ZJ90D/ZJ70D drilling rig parts (e.g., F2200HL mud pumps, JC90D drawworks) are engineered for deep drilling with enhanced load-bearing and pressure resistance; compact XJ series workover rig parts prioritize portability and quick installation for flexible on-site maintenance; specialized components like SL675 swivels and ZP495 rotary tables are optimized for large-scale drilling operations, while smaller models (e.g., DG50 hooks, F500 mud pumps) fit light to medium-duty rigs. Each part aligns with the specific power, load, and operational demands of its matching CPTDC model.

4. Structural Features

4.1 Material Selection

Key components adopt high-strength alloy steel (40Cr, 20CrMnTi) and wear-resistant cast iron for structural parts, drawworks, and rotary tables, treated with quenching, tempering, or carburizing processes to enhance hardness, toughness, and fatigue life. Hydraulic Disc Brakes use high-temperature resistant friction materials and corrosion-resistant steel for brake discs, complying with API 16C standards. Sealing elements for swivels and mud pumps use nitrile rubber (for general conditions) and fluorine rubber (for high-temperature, high-pressure, or corrosive environments) to ensure leak-free performance. Fasteners meet GB standards (10.9/12.9 grade) and API 7K requirements, ensuring secure connections under extreme operational loads.

4.2 Design Highlights

Parts follow CPTDC’s original modular and standardized design, optimizing stress distribution to avoid concentration during high-load, high-vibration operations. Hydraulic Disc Brakes (PSZ series) feature modular brake calipers for easy maintenance and adjustable braking force; Swivels (SL series) adopt sealed bearing structures to prevent drilling fluid contamination; Mud Pumps (F series) use replaceable wear plates and liners for cost-effective maintenance; Drawworks (JC series) feature reinforced drum designs for enhanced durability, with VFD/AC models offering energy-efficient power control. Standardized interfaces across all parts facilitate quick installation and replacement, reducing maintenance time and improving operational efficiency.

5. Applicable Working Conditions

Our spare parts are designed to adapt to the diverse and harsh working conditions of CPTDC drilling and workover rigs, including onshore oil and gas fields, shale gas exploration sites, coalbed methane wells, and geothermal drilling projects. They can withstand 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 operating in deserts, mountains, coastal areas, or plains, the parts maintain stable performance—corrosion-resistant coatings protect against drilling fluid and environmental damage, while high-temperature resistant components ensure reliability during prolonged high-load operation. The parts also meet the pressure and load requirements of deep drilling, medium-duty workover, and light drilling operations.

6. Maintenance & Service Recommendations

6.1 Routine Maintenance

1. Regular Inspection: Conduct weekly checks of key components—inspect hydraulic disc brakes for friction material wear and oil leaks, swivels for seal integrity, mud pumps for liner wear and fluid leaks, and drawworks for drum wear and wire rope alignment. Check fasteners for tightness and rotating parts (bearings, gears) for smooth operation. 2. Lubrication: Inject API-compliant high-temperature anti-wear grease into bearings, gears, and rotary tables every 120 working hours; use ISO VG 46 hydraulic oil for hydraulic systems (e.g., PSZ series brakes) and flush hydraulic lines quarterly to remove contaminants. 3. Cleaning: Regularly remove drilling fluid residues, dust, and debris from parts surfaces, especially mud pumps, swivels, and rotary tables, to prevent corrosion and blockage.

6.2 Replacement & Installation Guidelines

1. Replacement Timing: Replace parts according to CPTDC’s original maintenance manual or when faults occur—e.g., hydraulic brake friction material wear exceeding 3mm, mud pump liner wear exceeding 1mm, seal leakage, or gear tooth damage. 2. Installation: Use professional tools, follow CPTDC’s installation specifications, and torque fasteners to standard values. Ensure precise alignment of rotating parts (rotary tables, drawworks gears) to avoid premature wear; for hydraulic components, bleed air from the system after installation. 3. Post-Replacement Testing: Conduct a test run after replacement to verify no abnormal noise, vibration, or leaks, and confirm that all components operate in line with CPTDC’s performance standards.

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, component type, and part number, and label them clearly. Precision components (bearings, seals) should be stored in sealed packaging to prevent dust and moisture; hydraulic components and lines should be stored in moisture-proof containers, with empty lines sealed to avoid contamination. For long-term storage, apply anti-rust oil to metal parts and inspect quarterly for rust or damage.

Case 1: CPTDC ZJ50D Drilling Rig Hydraulic Disc Brake (PSZ75) Failure

Fault Phenomenon: A ZJ50D rig’s PSZ75 hydraulic disc brake had reduced braking force, leading to unstable drill string lowering. Diagnosis: Friction material wear exceeding the limit and hydraulic oil contamination, causing reduced pressure transmission. Solution: Replaced the friction pads with OEM-compatible parts, flushed the hydraulic system, and refilled with API-compliant hydraulic oil. Result: Braking force was fully restored, ensuring safe hoisting and lowering operations, and brake service life was extended by 50%.

Case 2: CPTDC XJ450 Workover Rig Mud Pump (F1600) Liner Leakage

Fault Phenomenon: An XJ450 workover rig’s F1600 mud pump had severe drilling fluid leakage from the liner, reducing circulation pressure. Diagnosis: Liner wear and seal damage due to prolonged use with abrasive drilling fluid, failing to maintain pressure integrity.Solution: Replaced the liner and fluorine rubber seals with CPTDC-compatible parts, adjusted the pump’s pressure settings, and installed a fluid filter. Result: Leakage stopped, circulation pressure stabilized, and the mud pump resumed normal operation.

Case 3: CPTDC ZJ70D Drilling Rig Rotary Table (ZP375) Power Transmission Failure

Fault Phenomenon: A ZJ70D rig’s ZP375 rotary table had intermittent power loss and abnormal noise during operation, affecting drill string rotation. Diagnosis: Worn gear teeth and insufficient lubrication, causing uneven torque transmission and gear misalignment. Solution: Replaced the worn gears with OEM-compatible precision parts, realigned the rotary table, and injected high-temperature anti-wear grease. Result: Power transmission became stable, abnormal noise was eliminated, and the rotary table operated smoothly.
