China Suppliers Factory for Diesel Engine Driven Crawler Water Well Drilling Rigs - Depth 200-1000m, Diameter 150-400mm
Fully Hydraulic Operation
The drilling speed, torque, propelling shaft pressure, countershaft pressure, propelling speed and lifting speed of the drilling rig can be adjusted at any time to meet the needs of different drilling tools and different construction techniques.
Top-Driven Rotary Propulsion
Top-driven rotary propulsion and lifting. It is convenient for picking up and unloading drill pipes, shortening the auxiliary time, and also favourable for following pipe drilling.
Multifunctional Drilling
All kinds of drilling techniques can be used on this drilling rig, such as: submerged hole drilling, mud drilling, tooth wheel drilling, pipe following drilling and core drilling which is under development and so on. The rig can be fitted with mud pumps, generators and welding machines according to customer requirements. The drilling rig is also equipped with various winches as standard.
High Operating Efficiency
Due to the full hydraulic and top-driven rotary propulsion lifting, adapted to a variety of drilling techniques and various drilling tools, convenient and flexible operation, fast drilling speed, short auxiliary time, and thus high operational efficiency.
Low Operating Cost
Drilling in the rock to submerged hammer drilling work metre drilling cost is low. Submersible hammer rock drilling has high operational efficiency and low drilling cost per metre.
High Outrigger Crawler Type
High outriggers are convenient for loading and transporting, and can be loaded directly without a crane. Crawler walking is more adaptable to move in the muddy site.
Role of Oil Mister
Drilling in the rock is dominated by the submerged hammer drilling process, the submerged hammer rock drilling operation is highly efficient, the lubricated impactor has a longer service life, and the cost of drilling per metre is low.
Drilling Rig Chassis
It can be tracked self-propelled chassis or vehicle-mounted self-propelled chassis.
Wide Range of Applications
Widely used in drilling water wells, testing wells, precipitation wells, rescue wells, ground source air-conditioning holes, coal bed methane, natural gas, oil extraction and other projects.

Frequently Asked Questions
What applications are these well drilling rigs suitable for?
These drilling rigs are widely used for water wells, testing wells, precipitation wells, rescue wells, ground source air-conditioning holes, coal bed methane, natural gas, oil extraction, and other construction projects.
What are the advantages of a fully hydraulic operation system?
Fully hydraulic operation allows the drilling speed, torque, propelling shaft pressure, countershaft pressure, propelling speed, and lifting speed of the drilling rig to be adjusted at any time. This ensures compatibility with different drilling tools and construction techniques.
How does the top-driven rotary propulsion system benefit operations?
The top-driven rotary propulsion and lifting system makes it highly convenient to pick up and unload drill pipes, which shortens auxiliary time and facilitates efficient follow-pipe drilling.
What drilling techniques can be performed with these rigs?
The rigs support a wide range of techniques, including submerged hole drilling, mud drilling, tooth wheel drilling, pipe following drilling, and core drilling. They can also be equipped with mud pumps, generators, welding machines, and standard winches according to customer needs.
Why are these drilling rigs cost-effective for rock drilling?
Rock drilling is dominated by the submerged hammer process, which is highly efficient. In addition, the integrated oil mister lubricates the impactor to extend its service life, keeping the drilling cost per meter very low.
What types of chassis options are available?
The drilling rig chassis can be configured as a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis. The high outrigger crawler design allows for easy loading and transport without a crane, and offers superior mobility on muddy sites.
