1.Power system maintenanceDaily check
① Oil level (maintain scale scale at 1/2-2/3)
② Air filter pressure difference (replace immediately if it exceeds 25kPa)
③ Coolant pH value (controlled between 8.5-10.5)
500 hours of maintenance
>l >Replace the fuel filter element (Cummins recommends using the FF5745 model)
>l >Clean the carbon deposits on the turbocharger (wire brush is prohibited, use carburetor cleaner)
Fault warning
>l >Continuous emission of black smoke: clogged fuel injectors or insufficient air intake
>l >Water temperature exceeds 95 ℃: Check if the thermostat or radiator fins are blocked
Hydraulic system
Key maintenance points
>l >Hydraulic oil cleanliness (NAS level 8 standard, quarterly testing)
>l >Pump body vibration value (axial vibration ≤ 4.5mm/s, using Fluke 810 vibrometer)
>l >Seal replacement cycle (Parker brand seal rings must be replaced every 2000 hours)
Operation taboos
>l >Prohibit mixing hydraulic oils of different brands (such as Shell and Mobil, which need to be thoroughly rinsed)
>l >Before starting in winter, the oil temperature needs to be
preheated to ≥ 15 ℃ (through the fuel tank heating plate)
Drill rod and drill bit
Maintenance Object | Operating specifications | Tools/Materials | International Standards |
Drill pipe thread | Apply EP-2 thread grease after each disassembly | Copper wire brush cleaning | API RP 7A |
Pdc bits | Cover the tooth tips with anti rust film during storage | VCI gas-phase rust proof paper | ISO 10407 |
Drill collar stabilizer | Scrap if radial wear exceeds 3mm | Laser caliper | API SPEC 7-1 |
Sleeve maintenance
Storage requirements
>l >Stacking no more than 5 layers, separated by wooden mats between layers (spacing ≥ 30cm)
>l >The end sealing cover maintains airtightness (in environments with humidity<60%)
Pre well inspection
>l >Ultrasonic testing (prohibited for wall thickness deviation>10%)
>l >Ellipticity measurement (straightening is required if it exceeds 1% of the nominal diameter)

5.Maintenance of well control system
Functional testing
>· >Weekly remote control console accumulator pressure detection (17.5-21MPa)
>· >Monthly full-size gate shear test (cutting time ≤ 45 seconds for a drill pipe with a diameter of 127mm)
Sealing management
>· >Circular rubber core storage temperature 10-25 ℃ (avoid direct sunlight)
>· >The amount of sealing grease added to the gate should be ≥ 4.5kg each time (using Shaffer special grease)
