Function Description

Key Product Functions

Each product is engineered to meet specific operational needs, with core functions focused on enhancing oilfield operation efficiency, safety, and stability, while addressing the practical needs of on-site work:

• Drilling Bits (HJT517G, SKG115GC): The Inserted and Inlaid Carbide Roller Bits are designed for drilling in diverse geological formations (sandstone, shale, hard rock), with high wear resistance and drilling efficiency, reducing bit replacement frequency and improving drilling progress.

• Hydraulic Components (PD4-41-0098 Shuttle Valve, 4WH6D50B Hydraulic Control Valve): Control the flow, pressure, and direction of hydraulic oil in drilling rig systems, ensuring precise operation of winches, hydraulic tongs, and balance cylinders. The Shuttle Valve PD4-41-0098 enables automatic switching of hydraulic circuits, enhancing operational flexibility.

• Winch Brake Operating Mechanism ZJ30: Controls the braking of ZJ30 drilling rig winches, ensuring safe lifting and lowering of drill pipes and equipment, preventing accidents caused by winch slippage.

• Filtration & Sealing Parts: Filter elements (FBX-400*30, 3827589) and strainers (5126000980) remove impurities from hydraulic oil and air, protecting core equipment from wear. Mechanical seals (666001006) and spring seals (ZJ45 260×300×20) prevent leakage of hydraulic oil and drilling fluid, maintaining system pressure integrity.

• Electrical Parts & Sensors: Total Hydrocarbon Sensor SP-1102 monitors hydrocarbon content in drilling environments to ensure operational safety. Air Conditioner Relay 753-3C-C1 TRANE ensures stable operation of drilling rig air conditioners, maintaining a comfortable working environment for on-site personnel. Audible Alarm 450103080000210000 provides timely alerts for equipment faults.

• Pumps & Heaters: High Pressure Ceramic Plunger Pump WS82 delivers stable high-pressure fluid for drilling and well completion operations. Industrial Heater BDKN-2.0C 2kW Explosion-proof 220V provides reliable heating in harsh oilfield environments, preventing equipment damage from low temperatures.

Structural Features

Design Advantages

All products adopt practical, industry-proven structural designs, balancing durability, compatibility, and ease of maintenance to adapt to the harsh and complex conditions of oilfield operations:

• High-Strength Material Selection: Drilling bits (HJT517G, SKG115GC) use high-quality carbide inserts for wear resistance; mechanical parts (roller shafts, connecting rods) are made of alloy steel,经过 heat treatment to improve hardness and load-bearing capacity, suitable for heavy-load drilling operations.

• Precision Machining: Hydraulic valves (PD4-41-0098, 4WH6D50B), bearings (DQ70BSC 4301000460 NU244MA/C3 6244), and flanges are manufactured using CNC precision machining, ensuring tight dimensional tolerance and perfect compatibility with original equipment, eliminating assembly errors.

• Sealing & Corrosion Resistance: Sealing elements use high-temperature, oil-resistant elastomers; anti-loosening flanges (DQ70 1.08.08.003) and corrosion-resistant coatings protect parts from high-salt, high-humidity oilfield environments, extending service life.

• User-Friendly & Maintenance-Friendly Design: Filter elements and mechanical seals are designed for quick replacement; adjusting washers (F2000000274) and adjusting screws (PSZ75A-3-04) allow easy on-site adjustment, reducing maintenance time and labor costs.

• Explosion-Proof & Safety Design: Industrial Heater BDKN-2.0C and electrical parts (Y/F08IB0P electromagnetic breaker) adopt explosion-proof structures, meeting the safety requirements of flammable and explosive oilfield environments.

Applicable Working Conditions

Our oilfield equipment parts are widely suitable for various oilfield operation scenarios, particularly adapting to the following harsh working conditions, and perfectly matching the operational requirements of ZJ series drilling rigs:

• Onshore & Offshore Drilling Rigs: Compatible with ZJ30, ZJ30DB, ZJ40L, ZJ45, ZJ60, ZJ70D, ZJ70DBS, ZJ70/4500DZ series drilling rigs, supporting shallow, medium, and deep well drilling operations in diverse geological conditions.

• High-Temperature & High-Pressure (HTHP) Environments: Boiler Quartz Tube Water Level Gauge AF 450℃, spring seals, and hydraulic valves can operate stably at temperatures up to 450℃ and pressures up to 100MPa, meeting HTHP well operation requirements.

• Corrosive & High-Humidity Scenarios: Anti-corrosion flanges, rubber throat bushes, and filtration parts resist corrosion from drilling fluid, seawater, and saline-alkali, making them suitable for offshore oilfields and coastal drilling sites.

• Heavy-Load & Continuous Operation: Winch brake mechanisms, thrust bearing assemblies, and plunger pumps are designed for long-term heavy-load operation, with low failure rates to ensure uninterrupted drilling and production.

• Flammable & Explosive Environments: Explosion-proof industrial heaters (BDKN-2.0C) and electromagnetic breakers (Y/F08IB0P) meet explosion-proof standards, ensuring safe operation in oilfield environments with flammable gases.

Maintenance & Care Suggestions

Proper maintenance and care are essential to extend the service life of oilfield equipment parts, reduce failure rates, and maintain operational efficiency. Below are practical, targeted maintenance recommendations that align with on-site operation habits:

• Regular Inspection: Conduct weekly visual checks of key parts (hydraulic valves, seals, filter elements) to detect wear, deformation, or leakage. For sensors (SP-1102) and alarms, test signal transmission monthly to ensure accurate operation.

• Filtration System Maintenance: Replace oil filter elements (FBX-400*30, 8N2556) and air filters (PA 3498) every 3-6 months or when differential pressure exceeds 0.5MPa. Clean strainers (5126000980) regularly to prevent blockage.

• Drilling Bit Maintenance: Inspect carbide inserts of HJT517G and SKG115GC bits after each drilling shift; replace worn inserts in a timely manner to maintain drilling efficiency. Clean the bit surface to remove rock debris.

• Hydraulic & Sealing Maintenance: Check hydraulic hoses (ZJ70D 10II-1000) for cracks or aging; replace damaged hoses immediately. Apply lubricating grease to shuttle valves and hydraulic control valves every 15 days to ensure smooth operation.

• Electrical & Auxiliary Maintenance: Keep explosion-proof heaters (BDKN-2.0C) and relays (753-3C-C1 TRANE) clean and dry to prevent short circuits. Calibrate solid phase content analyzers (ZNG-A) quarterly to ensure accurate data.

On-Site Fault Maintenance Cases

The following 3 real on-site fault cases provide practical guidance for solving common oilfield equipment problems, helping maintenance teams quickly diagnose and resolve issues, and reducing downtime:

Case 1: ZJ30 Winch Brake Failure

Fault Phenomenon: A ZJ30 drilling rig’s winch fails to brake effectively during lifting operations, posing safety risks. Inspection shows the Winch Brake Operating Mechanism’s internal components are worn, and the adjusting screw PSZ75A-3-04 is loose.

Solution: Disassemble the winch brake mechanism, replace worn internal parts, adjust the PSZ75A-3-04 screw to the specified torque, and test the brake performance. After maintenance, the winch brakes stably, ensuring safe operation.

Case 2: Hydraulic System Leakage in ZJ45 Drilling Rig

Fault Phenomenon: The ZJ45 drilling rig’s hydraulic system has oil leakage at the pump connection, leading to pressure loss. Inspection reveals the 666001006 Mechanical Seal is worn and damaged.

Solution: Replace the worn mechanical seal with a new 666001006 model, clean the pump shaft surface, and ensure proper installation with even torque. After replacement, the leakage is completely eliminated, and the hydraulic system pressure returns to normal.

Case 3: Drilling Bit Wear & Low Drilling Efficiency

Fault Phenomenon: An Inserted Carbide Roller Bit 5-7/8″ HJT517G shows severe wear after drilling 500 meters, resulting in reduced drilling speed. Inspection confirms the carbide inserts are worn and some are broken.

Solution: Replace the worn HJT517G bit with a new one, select the appropriate bit type according to the geological formation, and adjust drilling parameters. After replacement, the drilling speed is restored, and the bit service life is extended to the standard 800-1000 meters.
