How to choose drill bits for different working formations of water well drilling rigs?
The drill bit is one of the important drilling tools in the drilling of water well drilling rigs. It can be said that without the drill bit, the water well drilling rig equipment cannot start production normally. This shows the importance of the drill bit in the water well drilling rig. For different types of water well drilling rig equipment, different drill bits are required in production. When selecting a drill bit for water well drilling rig equipment, the following aspects should be paid attention to:
1. When producing in soft rock with better drillability, the drilling speed is faster, and it is necessary to choose a larger slag discharge and higher slag quality, preferably a four-wing shape.
2. When producing in hard rock, due to the high strength of the rock, each column tooth and bit need to bear a large amount of load, so it is necessary to choose a bit with higher strength of the bit body and column tooth.
3. When drilling rocks containing clay, the slag discharge hole is often blocked due to the loose clay, so you can choose a side slag discharge drill.
4. When drilling holes in rocks with better toughness, you can choose a wedge-shaped bit to ensure safe production.
