The Polar Low Temperature Drilling Rig Aurora ZJ80 is a customized ultra-heavy-duty low-temperature resistant drilling rig independently developed for.
The Polar Low Temperature Drilling Rig Aurora ZJ80 is a customized ultra-heavy-duty low-temperature resistant drilling rig independently developed for polar, alpine and extreme cold-region ultra-deep well operations. Designed and certified in accordance with API-4F, API-7K and ISO9001 international standards, this Aurora series rig breaks through the temperature limitation of conventional drilling equipment, adopting full-system low-temperature anti-brittle, cold-start and thermal insulation technologies. It adopts modular skid split structure suitable for polar transportation and seasonal construction. Specially applied for 6000-8000m ultra-deep oil and gas exploration, geothermal resource development and scientific geological drilling in Arctic, sub-arctic and high-altitude frigid regions, it is professional extreme-condition drilling equipment tailored for global cold-region energy strategic development projects.
All structural steel, hydraulic components, electrical elements and sealing parts adopt special low-temperature resistant materials after cryogenic treatment. The whole machine supports stable operation at ultra-low ambient temperature, solving the problems of brittle fracture, oil circuit solidification and electrical failure of conventional rigs in polar cold environments.
Equipped with customized hydraulic oil heating system, pipeline constant-temperature thermal insulation device, electrical cabinet anti-condensation heating module and cabin integral heating system. It realizes zero-failure cold start and continuous stable operation in extreme frigid weather, completely adapting to polar seasonal low-temperature working conditions.
Adopts super-rigid K-type open-front derrick and reinforced heavy-duty box substructure, with ultra-high hook load reserve. It maintains excellent structural stability and load-bearing performance under low-temperature cold-brittle environment, meeting long-cycle heavy-load drilling requirements of 8000m ultra-deep wells in cold regions.
Optimized skid split layout conforms to polar logistics and seasonal transportation conditions. All modules adopt anti-freezing, snow-proof and ice-prevention structural optimization, convenient for field assembly, disassembly and winter maintenance in remote alpine and polar well pads.
Equipped with low-temperature overload protection, pipeline anti-freezing pressure protection, snow load structural safety verification and full-machine cold-region safety interlock system. It effectively avoids equipment damage and safety accidents caused by extreme low temperature, snow and frost, ensuring high safety and reliability of polar drilling construction.
