Is the depth of the water well drilling rig insufficient? Optimize starting from the selection of the drill bit

When a Буровая установка для бурения скважин на воду fails to reach the expected depth or shows low efficiency, many often overlook a key factor – the drill bit. A suitable drill bit can not only improve drilling efficiency but also effectively increase the drilling depth.

Different types of drill bits are suitable for various geological conditions. For operations in rock layers, tungsten carbide drill bits are a good choice. Made of high-strength tungsten carbide material, they have extremely high hardness, which can effectively break hard rocks, reduce bit wear, and enhance drilling speed. In soil or sand layers, however, spiral drill bits are more appropriate. The unique spiral structure of spiral bits can quickly carry cuttings to the surface, avoiding drilling efficiency loss due to cuttings accumulation and preventing hole collapse to ensure the advancement of drilling depth.

 

Besides geological conditions, the size specifications of drill bits are also crucial. A drill bit with too small a diameter may cause excessive drilling resistance, affecting depth and efficiency. An overly large bit, on the other hand, may exceed the rig’s load capacity, similarly reducing operational effectiveness. When selecting a drill bit, it is essential to precisely match the appropriate bit diameter and length based on the rig’s model, power, and actual geological conditions.

 

Regular inspection and maintenance of drill bits are also necessary. After prolonged use, drill bits will wear out, and the cutting edges will become dull, which greatly reduces drilling efficiency. When severe wear is found, the drill bit should be repaired or replaced in a timely manner to ensure it always remains in good working condition. Starting with the correct selection and maintenance of drill bits is an important first step to solve the problem of insufficient depth in water well drilling and improve operational efficiency.water well drilling rig
