Applicable to onshore ultra-deep vertical well, high-deflection directional well mud circulation, well killing pressure regulation, winch lifting linkage and fluid end overpressure protection working scenarios.

2.5 Senior Field Drilling Engineer Maintenance & Fault Prevention Advice

Implement full pump disassembly overhaul every 2000 working hours; replace diaphragm and valve cover seal in paired sets during fluid end maintenance; torque 1 1/4″-8 UNC header nut to 470ft-lbs standardized tightening torque; inspect shear pin surface micro-crack every 360 working hours; select matched 190/200 series O-rings per GB/T3452.1 standard strictly; clean mudguard gap regularly to avoid piston rod surface mud scratch; test safety valve opening pressure quarterly on site; never mix 160mm and 170mm piston rubber for mixed assembly.
