The Geothermal Compact Skid Drilling Rig GH4500 is a professional compact skid-mounted drilling rig specially optimized for medium-deep geothermal well.
The Geothermal Compact Skid Drilling Rig GH4500 is a professional compact skid-mounted drilling rig specially optimized for medium-deep geothermal well exploration and development. Manufactured in strict accordance with API and ISO9001 international quality standards, this rig adopts an integrated compact skid structure, breaking the bulky layout of traditional oilfield drilling rigs. It is designed for 3000-4500m medium-deep geothermal well drilling, adapting to high-temperature stratum, complex lithology and limited-site construction conditions of geothermal projects. With highly integrated configuration, flexible deployment and strong high-temperature formation adaptability, it is the core dedicated equipment for commercial geothermal energy development, urban geothermal heating and underground thermal resource exploration projects worldwide.
Adopts ultra-compact integrated skid modular design, integrating derrick, drawworks, power unit and control system as a highly centralized unit. The overall occupied area is greatly reduced, perfectly adapting to narrow construction sites in urban areas, mountainous geothermal fields and suburban thermal resource development projects, solving the site restriction problem of traditional large drilling rigs.
All core hydraulic, sealing and electrical components are upgraded with high-temperature resistant materials, specially optimized for geothermal well high-temperature stratum working conditions. It effectively resists downhole high-temperature fluid erosion and stratum thermal stress, avoiding component aging and failure caused by long-term high-temperature operation, greatly improving construction stability of geothermal wells.
Equipped with stepless speed regulation drive system, which outputs stable and adjustable torque and lifting force. It adapts to complex and variable geothermal stratum characteristics such as fractured rock, loose lithology and uneven hardness, realizing efficient drilling, reaming and well completion operations and reducing wellbore collapse risks.
The compact skid structure supports integral hoisting and containerized transportation without complicated disassembly and assembly. It greatly shortens on-site rig-up and commissioning cycle, reduces cross-region migration costs, and is highly suitable for distributed and scattered geothermal well construction scenarios.
Optimized power matching reduces idle power consumption, with low noise and low vibration during operation. Equipped with matched closed mud circulation system interface, it meets environmental protection construction requirements of urban and scenic geothermal projects, realizing green and efficient geothermal drilling.
