Customizable High Efficiency Portable Water Borehole Drilling Machine 50-200m Drilling Depth

This 200m customized portable water well drilling rig machine is designed for mining and rocky drilling works. It effectively solves problems related to well drilling, geological exploration, and soil testing, serving as a medium shallow hole core drilling machine. The utility model offers advantages of small size, light weight, large power, and wide application range, making it especially suitable for constructions of hydroelectric power stations, highways, railroads, and harbors.

• Very powerful performance in soil, sand, hard rock, and various land conditions
• Three types of drill bits available: three-wing bit, alloy bit, and diamond bit for both soft and hard ground drilling
• Diamond drill bit particularly effective in drilling hard rocks
• Hydraulic control system for improved working efficiency and labor force savings
• Mounted wheel or trailer design for easy transportation by car or tractor
• Power options: diesel engine or electric motor available per customer request

The drill bit plays a crucial role in water well drilling operations, directly affecting efficiency and quality. Proper selection and usage of the drill bit are essential for optimal production and operation.

Key Operational Considerations:

• After completing the drilling structure, replace the central drilling tool promptly by first cleaning the hole bottom and blowing away residue
• Stop drill bit rotation before slowly lifting the drilling tool - the lifting force should be just sufficient to lift the tool
• Monitor casing follow-up during drilling and maintain hole cleanliness when necessary
• Avoid forcing the drill bit out during the drilling process
• For excessive residual rock slag that may jam the eccentric bit, apply air pressure to clean the hole and enable DTH hammer operation before lifting the central drilling tool

Drill pipe is a steel pipe with threaded ends used to connect surface drilling equipment with bottom hole drilling and grinding equipment. Its purpose is to transport drilling mud to the drill bit and facilitate raising, lowering, or rotating bottom hole devices. Drill pipes must withstand significant internal and external pressure, torsion, bending, and vibration. In oil and gas exploitation, drill pipes can be reused multiple times.
