How To Use The "operation Record" of A Second-hand Rotary Drilling Rig? Maintenance And Efficiency Analysis of Auxiliary Equipment

The operation records of second-hand rotary drilling RIGS are not merely "running accounts", but rather the core basis for equipment condition monitoring, maintenance planning and construction efficiency optimization. By standardizing records and applying them reasonably, not only can fault risks be avoided in advance, but also the cost performance of construction can be improved. The following is an analysis of the usage methods of operation records from six dimensions:

1. Clearly record the core content: It is necessary to record in detail the basic information such as the operation date, duration, drilling depth, and geological type. At the same time, mark the key status data such as the number of equipment starts and stops, abnormal sounds, and hydraulic oil temperature to provide a complete basis for subsequent analysis.

2. Assist in formulating maintenance cycles: By comparing the "service life of vulnerable parts" (such as drill pipe joints and drill bit blades) in the operation records with the standards in the equipment manual, the replacement nodes of accessories can be accurately determined, avoiding excessive maintenance or malfunctions caused by aging accessories.

3. Trace the root cause of the fault: If the equipment experiences repeated malfunctions (such as stuck drill or insufficient power mentioned earlier), the operation records can be retrieved to check the parameters before the fault, such as the rotational speed, drilling pressure, and hydraulic pressure, to quickly determine whether it is caused by improper operation parameters or premature wear of components.

4. Optimize construction efficiency parameters: Analyze the operation records under different geological conditions, statistically analyze the matching data of "drilling speed - drilling pressure - rotational speed", and screen out the optimal parameter combination. For example, the rotational speed and drilling pressure adopted in the clay layer can improve construction efficiency when applied to similar working conditions.

5. Evaluate the overall performance of the equipment: Regularly summarize the operation records, compare the "average daily operation volume" and "failure frequency" at the time of new purchase with the current one, and determine the performance degradation degree of the core components of the equipment (such as the engine and hydraulic system), providing decision-making references for subsequent equipment upgrades or major overhauls.

6. Standardize operation procedures: Combine the "compliance operation data" in the operation records with "fault cases caused by abnormal operations" as training materials for operators to help them understand the impact of correct operation on equipment lifespan and construction efficiency, and reduce human errors.

In conclusion, the operation records of second-hand rotary drilling RIGS serve as the "data hub" for equipment management. Their value lies not only in "recording", but also in achieving precise maintenance and optimized efficiency through data mining. Only by attaching importance to and making good use of records can second-hand equipment perform stably, reduce operating costs and ensure the efficient progress of construction.
