The Multi Purpose Geothermal Drilling Rig NT G1200 is a heavy duty full hydraulic crawler mounted multi functional drilling rig developed for medium deep geothermal well construction, manufactured complying with international geothermal engineering and mechanical safety standards.
The Multi Purpose Geothermal Drilling Rig NT G1200 is a heavy duty full hydraulic crawler mounted multi functional drilling rig developed for medium deep geothermal well construction, manufactured complying with international geothermal engineering and mechanical safety standards. Rated for 1200 meter geothermal well drilling, NT G1200 integrates geothermal heat exchange borehole drilling, hot spring well drilling, large diameter water well drilling and geological coring capabilities. Adopting reinforced crawler undercarriage and high torque top drive full hydraulic system, the rig supports both mud circulation drilling and DTH air percussion drilling processes. It delivers stable performance in hard rock, fractured formations and high temperature geothermal stratums. Equipped with high rigidity mast, heavy load hydraulic feeding pullback mechanism and multi point leveling outriggers, the equipment ensures high efficiency borehole forming and long time continuous field operation. Widely used for ground source heat pump projects, geothermal resource development, industrial water source wells and engineering geotechnical investigation worldwide, NT G1200 acts as a reliable multi purpose drilling solution for geothermal contractors and drilling engineering enterprises.
Supports dual drilling technologies of mud rotary drilling and DTH air percussion drilling. It can switch flexibly between geothermal borehole, hot spring well, large diameter water well and core sampling tasks. Optimized power head structure adapts to high temperature down hole environment and abrasive hard rock formations, meeting diversified geothermal engineering construction requirements.
Industrial heavy duty hydraulic top drive provides stepless adjustable rotary speed and constant high torque output. Hydraulic feeding and pull back force can be precisely regulated according to stratum hardness, effectively reducing drill sticking risks in fractured and hard rock. Stable power output improves drilling efficiency and borehole quality for 1200 meter medium deep geothermal wells.
Heavy duty crawler travelling structure with low ground pressure design realizes self propelled transition on mountainous, hilly, muddy and gravel sites. In situ steering and flexible positioning eliminate dependence on extra transportation cranes. Hydraulic leveling outriggers guarantee whole machine stability during high load deep hole geothermal drilling operations.
Highly modular design for power unit, hydraulic station and drilling working assembly. Hydraulic automatic mast erecting shortens rig up time significantly upon site arrival. No complicated on site assembly or foundation treatment is required, improving response efficiency for batch geothermal project construction.
Key load bearing components adopt high strength heat resistant and anti corrosion material treatment. Hydraulic and electrical assemblies are upgraded with high temperature resistant sealing, dust proof and splash proof modules. The rig can sustain stable operation in high temperature geothermal construction sites, arid desert and alpine low temperature outdoor environments.
Intuitive integrated control console simplifies operation logic and lowers operator skill threshold. Main hydraulic and wearing parts adopt globally available standard specifications. Modular assembly structure facilitates inspection, component replacement and on site troubleshooting, cutting long term operating and maintenance costs.

A geothermal budget is decided by how many boreholes a crew can finish in a season, and the NT-G1200 multi-purpose geothermal drilling rig is built to keep that crew moving. Rated for 1200 m geothermal holes with a 5200 N·m hydraulic power head and stepless 0-1100 r/min rotation, it drills 150-300 mm boreholes and switches between mud rotary, DTH air percussion and core sampling without re-rigging. The reinforced crawler undercarriage self-deploys at up to 2.6 km/h on 28-degree grades, so ground-source heat-pump and hot-spring crews reach muddy, hilly sites without a crane, while the 90/98 kN feed-and-pullback handles casing and high-temperature hard rock. It is the geothermal drilling rig for medium-deep, scattered borehole campaigns; 4000 m deep enhanced-geothermal wells belong to a far heavier land class.
Before you request an NT-G1200 drilling rig quotation, describe the borehole purpose, because diameter drives everything. A ground-source heat-exchange bore needs a different 150-200 mm string than a 300 mm production water well, and hot-spring holes add high-temperature downhole tooling. Confirm the site access: the crawler unit needs only a workable track, not a hard road, but we size the mud or air package to the formation. State the target reservoir temperature and whether grid power exists — the 132 kW diesel engine is standard, and an electric-drive package is available for fenced compounds.
Bore diameter, power unit and mud-or-air package are chosen per borehole plan, so the NT-G1200 has no catalogue price. Operator training is available at your site or at our Jingzhou works, useful for heat-pump contractors adding drilling in-house; outline the bore count and target depth and the offer comes back with the tooling list.
Customize power head torque and hydraulic thrust for extra hard geothermal rock formations; match high temperature resistant drill string package to improve service life under geothermal well working conditions.
Optional widened anti sink crawler tracks for swampy and soft ground geothermal construction sites; reinforced shock absorbing chassis for mountainous complex terrain.
Optional enhanced high temperature resistant sealing module for geothermal high heat borehole operation; ultra low temperature cold start package for alpine geothermal development regions.
Optional real time drilling parameter monitoring, depth recording and data export module for digital geothermal site construction management.
