On-Site Fault Maintenance Cases
Case 1: Pressure Sensor Measurement Inaccuracy
Fault Phenomenon: The pneumatic anti-seismic pressure sensor YPQ-01-Z/70A in the drilling throttling system displayed obvious measurement deviation, leading to incorrect control of the throttling manifold. Reason Analysis: The sensor’s sensing port was blocked by mud impurities, and the internal diaphragm was worn due to long-term high-pressure impact.Solution: Disassemble the sensor, clean the sensing port with clean compressed air, replace the worn diaphragm, and calibrate the sensor according to ISO 14001 standards. After reinstallation, the measurement accuracy was restored, and the throttling system operated normally. Key Reference: Regular cleaning and calibration of sensors are critical to ensure measurement accuracy.
Case 2: High Pressure Stop Valve Leakage
Fault Phenomenon: The high pressure stop valve JZF-00-316SS leaked during high-pressure operation, causing pressure loss in the drilling system. Reason Analysis: The valve seat and valve core were worn by fluid impurities, and the PTFE seal was aging. Solution: Replace the worn valve seat, valve core, and seal, clean the valve body internal cavity, and conduct a pressure test according to API 6D standards (test pressure 1.5 times the rated pressure). After maintenance, the valve had no leakage, and the system pressure remained stable.
