Precautions for Using Water Well Drill Bits

Safe Operation, Prevention First

When using the water well drill bits for drilling operations, safety is always the top priority. Before operation, be sure to wear personal protective equipment such as safety helmets, safety goggles, dust masks, and anti-smash shoes. At the same time, ensure that the drilling rig is stable to avoid tilting or collapsing during operation. The installation and removal of the water well drill bits should be performed by professionals, following operational procedures to prevent accidents.

Reasonable Selection to Adaptation the Well Conditions

Different geological conditions require different types of water well drill bits. For instance, diamond drill bits are suitable for hard rock layers, while roller cone bits or drag bits can be used for soft soil layers. Therefore, when selecting water well drill bits, it is necessary to fully consider factors such as well depth, geological structure, and rock hardness to ensure that the type of drill bit matches the well conditions, thereby improving drilling efficiency and reducing wear.

Regular Maintenance to Extend Lifespan

Water well drill bits may experience wear or damage after frequent use, making regular inspection and maintenance critical. After each use, clean the mud and debris off the surface of the water well drill bits and check whether the cutting edge of the bits are sharp. Severely worn bits should be replaced promptly. During the drilling process of the water well rig, it is also essential to carefully monitor the progress of the casing, understand the specific conditions within the borehole in a timely manner, and maintain the borehole cleanliness when necessary. Additionally, ensuring proper maintenance of the lubrication system can reduce friction and wear, thereby extending the lifespan of the water well drill bits. The drilling process should avoid forceful extraction, and attention should be paid to maintaining the lubrication system to ensure the drill bit operates under good lubrication conditions.

Moreover, sometimes a considerable amount of residual rock debris may remain at the bottom of the hole, which can cause the eccentric drill bit's rotating part to become jammed, impacting its retraction and production. In such cases, compressed air must be delivered to clean the borehole again, allowing the down-the-hole hammer to operate for a short time before resuming the lifting operation of the central drilling tool.

Only by strictly adhering to these precautions can the drilling operations be carried out safely and efficiently, extending the service life of the water well drill bits and reducing operational costs.
