2. Key Product Function & Structural Characteristics

2.1 Basic Functional Description

The complete set of accessories undertakes multiple core functions of drilling equipment operation. The drilling fluid stuffing box, piston seal and various gaskets realize full sealing of hydraulic and drilling fluid systems, preventing medium leakage in high-pressure working environments. Main shafts, shaft sleeves and clamping brackets undertake the structural support and power transmission of drilling equipment. Clamp plates, torque increasing devices and wire rope components ensure stable load-bearing and safe lifting of drilling tools. Hydraulic accessories including overflow valves, check valves and assembled hoses maintain the stable pressure operation of the hydraulic station system, while lock devices and limit structural parts avoid equipment displacement and structural failure under dynamic load.

2.2 Unique Structural Features

All parts adopt integrated precision casting and CNC finishing process, with smooth matching surfaces and zero deviation in assembly tolerance. The U-shaped stop bracket and groove nut adopt anti-loosening structural design, which can resist frequent vibration of drilling equipment for a long time. The compressed spring and wear-resistant lining plate adopt enhanced material structure, avoiding elastic fatigue and surface abrasion under long-term high-load operation. The transition plate and oil tank shell adopt integrated molding structure, reducing assembly gaps and improving the overall structural rigidity of the equipment. All sealing parts adopt composite rubber and metal composite structure, adapting to high-pressure and variable-temperature drilling medium environment.

3. Applicable Working Conditions & Authoritative Certification

This series of drilling accessories is suitable for land conventional oil and gas drilling, shallow sea platform drilling, well workover and equipment maintenance operations, adapting to ambient temperatures ranging from -30℃ to 55℃ and system working pressure up to 35MPa. It is fully compatible with mainstream medium and large drilling rig models in the petroleum industry, and all wire rope products strictly comply with API 9A international manufacturing standards, while customized DQ series parts pass petroleum equipment quality inspection certification. Independent third-party test data shows that the structural parts can bear continuous dynamic load of 800kN without deformation, and the sealing accessories can maintain stable sealing performance after 5000 hours of continuous working operation. Relying on professional petroleum accessory production technology and long-term supporting experience for oilfield engineering projects, the products have passed repeated field verification of multiple domestic and overseas oilfield projects, with strong industry authority and practical applicability.

4. Field Maintenance & Operation Suggestions

In daily equipment maintenance, operators need to regularly check the tightness of bolts, cotter pins and gaskets, and replace aging sealing rings and hoses every 12 months in conventional working conditions. For core load-bearing parts such as main shafts and lifting lugs, regular surface wear detection is required every 6 months, and parts with wear depth exceeding 0.5mm need to be replaced in time to avoid structural safety hazards. The hydraulic valve assembly and cable trough of hydraulic station need regular dust and oil dirt cleaning to prevent pipeline blockage and circuit abrasion. Engineers’ practical operation reminder: do not use non-standard universal parts for temporary replacement during equipment failure maintenance, which will easily cause pressure instability and structural vibration damage of the whole equipment. All accessories support disassembly, replacement and independent maintenance, effectively reducing later maintenance difficulty and time cost.

5. On-Site Fault Maintenance Cases

Case 1: Daqing Onshore Oilfield, Drilling Rig Model ZJ40

The equipment operated under 620kN continuous load, with hydraulic system leakage caused by aging piston seal (1300108744), resulting in 15% pressure drop of the hydraulic station. After replacing the original matched piston seal, the hydraulic system pressure recovered to the standard 28MPa, maintaining stable operation for 18 consecutive months, and the on-site engineering team reported completely solved leakage failure.

Case 2: Tarim Oilfield, Workover Rig Model XJ350

Long-term vibration caused loosening of auxiliary channel fixing bracket (1200529332), leading to equipment operational jitter and reduced drilling efficiency. After replacing the original customized bracket, the equipment operation vibration amplitude was reduced by 0.3mm, the running stability was significantly improved, and the on-site team confirmed no jitter fault occurred in subsequent high-load operation.

Case 3: Bohai Offshore Oil Platform, Drilling Rig Model HXJ180

High-temperature and high-humidity working environment caused aging and failure of assembled hose (1300117960), resulting in unstable hydraulic oil supply. After replacing the special anti-corrosion and high-temperature resistant matched hose, the pipeline pressure fluctuation was controlled within 0.2MPa, adapting to offshore harsh working conditions, and the equipment operated stably for 16 months without failure.

Case 4: Sichuan Shale Gas Oilfield, Drilling Rig Model ZJ50

Insufficient torque during drilling operation was caused by wear of torque increasing device (DQ027.02.02.00Ⅱ). After replacing the standard torque increasing accessory, the equipment output torque increased to the standard rated value, the drilling progress efficiency was effectively improved, and the customer was satisfied with the fault repair effect and equipment stability improvement.
