On-Site Fault Maintenance Cases

Case 1: Hydraulic Power Tong Clamping Failure

A drilling site reported that the XQ114-6YB hydraulic power tong failed to clamp drill pipes, leading to drilling downtime. After inspection, the jaws (alloy steel 40Cr) were severely worn—wear thickness exceeded 1.2mm, which was beyond the safe use limit (≤1mm). At the same time, the hydraulic system had slight oil leakage, resulting in insufficient clamping pressure, and the seal ring of the hydraulic cylinder (Viton rubber FKM) was aged and cracked, further exacerbating pressure loss.

Fault Cause Analysis: 1. Long-term frequent clamping of drill pipes caused continuous friction between the jaws and the pipe wall, leading to excessive wear of the alloy steel jaws; the on-site maintenance personnel failed to check the jaw wear status regularly according to the requirements. 2. The seal ring of the hydraulic cylinder had been in service for more than 350 working hours, exceeding the recommended replacement cycle (300 working hours), and the high-temperature and high-pressure environment on the drilling site accelerated the aging and cracking of the Viton rubber, resulting in hydraulic oil leakage. 3. The hydraulic oil was not filtered and replaced on time, and a small amount of impurities caused slight wear to the hydraulic valve core, affecting the pressure stability of the system.

Maintenance Solution: 1. Replace the worn jaws with new ones of the same model (matching XQ114-6YB hydraulic power tong, material 40Cr alloy steel), and adjust the clamping gap to ensure that the clamping force is uniform when contacting the drill pipe. 2. Replace the aging hydraulic cylinder seal ring with a new Viton rubber (FKM) seal ring, clean the sealing surface before installation, and apply a small amount of high-temperature resistant lubricating oil to enhance sealing performance. 3. Filter the hydraulic system oil completely, remove impurities, and supplement new hydraulic oil that meets the ISO VG 46 standard; check the hydraulic valve core for wear, and clean it if there is slight wear, or replace it if the wear is serious. 4. Tighten all hydraulic pipeline joints to avoid secondary leakage.

Post-Maintenance Effect: After the above maintenance operations, the hydraulic power tong can clamp the drill pipe stably, the clamping force meets the operating requirements, there is no oil leakage in the hydraulic system, and the equipment resumes normal operation. The drilling downtime caused by the fault is controlled within 2 hours, which effectively reduces the economic loss caused by equipment failure.

Preventive Measures: 1. Strictly implement the regular inspection system, check the wear status of the jaws every 80 working hours, and replace them in time when the wear exceeds the limit. 2. Replace the hydraulic cylinder seal ring every 300 working hours, and store the spare seal ring in a dry and cool environment to avoid aging caused by moisture and high temperature. 3. Replace the hydraulic oil every 500 working hours, and install a high-precision filter at the oil inlet to prevent impurities from entering the system. 4. Train on-site maintenance personnel to master the key points of daily inspection and maintenance of hydraulic power tongs, and record the maintenance status in detail for traceability.

Case 2: Plunger Pump Efficiency Reduction and Leakage

During the operation of the SM2250 plunger pump at a drilling site, it was found that the pump discharge pressure decreased significantly, the flow rate was unstable, and there was obvious oil leakage at the valve seat, resulting in a reduction in drilling fluid circulation efficiency and affecting the normal progress of drilling operations. The on-site maintenance team conducted a comprehensive inspection of the plunger pump and its spare parts.

Fault Cause Analysis: 1. The plunger of the plunger pump (material 316L stainless steel) was severely worn due to long-term erosion by high-pressure drilling fluid, and the surface of the plunger had obvious scratches and pitting, which led to poor sealing between the plunger and the cylinder liner, resulting in internal leakage of the pump and reduced efficiency. 2. The valve seat (matching SM2250 plunger pump) was worn, the sealing surface was uneven, and the valve core could not be tightly closed, resulting in external leakage of the pump and further loss of pressure. 3. The hydraulic oil in the plunger pump had deteriorated due to long-term high-temperature operation, and the lubrication performance decreased, which accelerated the wear of the plunger and valve seat. 4. The on-site personnel did not check the operation status of the plunger pump in time, and failed to find the early wear and oil deterioration problems of the parts.

Maintenance Solution: 1. Replace the worn plunger and valve seat with new spare parts of the same model (plunger material 316L stainless steel, valve seat matching SM2250 plunger pump), and polish the sealing surface of the cylinder liner to ensure good fit with the new plunger. 2. Drain all the deteriorated hydraulic oil in the plunger pump, clean the pump cavity and oil pipeline thoroughly, and inject new hydraulic oil that meets the ISO VG 46 standard. 3. Check the tightness of all pipeline joints and valve connections, and tighten them in time if there is any looseness; install a pressure gauge at the pump outlet to monitor the discharge pressure in real time. 4. Test the plunger pump after maintenance, adjust the pump pressure and flow rate to the rated range, and confirm that there is no leakage and the operation is stable.

Post-Maintenance Effect: After maintenance, the discharge pressure of the SM2250 plunger pump returns to the rated value (≥35MPa), the flow rate is stable, there is no oil leakage at the valve seat and pipeline joints, the drilling fluid circulation efficiency is significantly improved, and the drilling operation resumes normal progress. The service life of the new plunger and valve seat is expected to reach more than 500 working hours under standard maintenance conditions.

Preventive Measures: 1. Check the surface condition of the plunger and the sealing status of the valve seat every 100 working hours, and clean the plunger surface regularly to remove sediment and corrosion products. 2. Replace the hydraulic oil every 500 working hours, and check the oil temperature regularly during operation to ensure that it does not exceed 80℃, so as to avoid oil deterioration. 3. Install a filter at the inlet of the plunger pump to filter the drilling fluid and hydraulic oil, reduce the erosion of impurities on the plunger and valve seat. 4. Formulate a regular maintenance plan for the plunger pump, record the replacement time of spare parts and the status of oil replacement, and ensure that the maintenance work is in place.

Case 3: DAS System Explosion-Proof Plug Failure

The DAS SYSTEM (model YGC-EX4P4P-6) at a hazardous drilling site had a malfunction— the explosion-proof plug (model PLUG EX FOR DAS SYSTEM YGC-EX4P4P-6) could not be plugged in smoothly, and there was poor contact after forced plugging, resulting in intermittent power failure of the system and potential safety hazards. Since the drilling site is a hazardous area, the system failure must be solved in time to avoid safety accidents.

Fault Cause Analysis: 1. The thread of the explosion-proof plug (material brass H62) was severely worn due to frequent plugging and unplugging on site, and there were thread glitches, which made it difficult to plug in and out smoothly; at the same time, the wear of the thread led to poor contact between the plug and the socket, resulting in intermittent power failure. 2. The explosion-proof surface of the plug was scratched by sharp objects during transportation and use, and the explosion-proof performance was reduced; moisture intruded into the plug through the scratches, causing internal corrosion of the contact points, further exacerbating poor contact. 3. The on-site operators did not plug and unplug the plug gently according to the operating specifications, and often used excessive force, which accelerated the wear of the thread and the damage of the explosion-proof surface. 4. The plug was not protected when not in use, and dust and moisture accumulated on the contact surface, affecting the contact performance.

Maintenance Solution: 1. Replace the worn explosion-proof plug with a new spare part of the same model (PLUG EX FOR DAS SYSTEM YGC-EX4P4P-6), ensure that the thread is intact, the explosion-proof surface is smooth and free of scratches, and the material meets the explosion-proof requirements (brass H62 + explosion-proof plastic PA66). 2. Clean the explosion-proof socket matching the plug, remove dust and corrosion products on the contact surface, and check whether the socket thread and explosion-proof surface are intact; if there is slight wear, polish it with a special tool, and replace it if the wear is serious. 3. Apply a small amount of anti-corrosion agent on the thread and contact surface of the plug to prevent corrosion and improve the smoothness of plugging and unplugging; ensure that the plug is plugged in in place during installation to avoid poor contact. 4. Conduct an explosion-proof test on the replaced plug and socket to confirm that the explosion-proof performance meets the national standard (GB 3836-2010) and there is no potential safety hazard.

Post-Maintenance Effect: After replacing the explosion-proof plug and conducting related treatments, the plug can be plugged in and out smoothly, the contact is good, the DAS SYSTEM resumes stable operation, and there is no intermittent power failure. The explosion-proof performance of the plug and socket meets the requirements of the hazardous drilling site, effectively eliminating potential safety hazards.

Preventive Measures: 1. Standardize the operation of on-site operators, require them to plug and unplug the explosion-proof plug gently, and avoid using excessive force to damage the thread and explosion-proof surface. 2. Install a protective cover for the explosion-proof plug and socket when not in use to prevent dust, moisture and sharp objects from damaging the parts. 3. Check the thread, contact surface and explosion-proof surface of the plug every 60 working hours, clean it regularly, and apply anti-corrosion agent; replace the plug in time if there is obvious wear or damage. 4. Store the spare explosion-proof plug in a dry, clean and explosion-proof environment, avoid collision and moisture, and ensure that the spare parts are intact when in use.
