The special geological conditions of fissures and fault zonessignificantlyaffect water well drilling bits. water well drilling rig .Due to broken rocks and large hardness differences, bits endure uneven impacts during drilling, accelerating cutting tooth wear. Especially in dense fissure areas, bits easily collide with fissure edges, causing damage like chipped or lost teeth. Different bit types perform differently in such zones:
Tungsten carbide bits are wear-resistant but prone to local wear on sharp fissured rocks.
PDC bits are efficient in soft rocks but easily damaged in hard rock fissures.
To tackle these issues:
Reasonably select bit types based on rock characteristics.
Regularly inspect and replace bits to maintain drilling efficiency.
Prioritize proactive maintenance to ensure drilling quality.water well drilling rig
