explorationmultifunctiongeothermal

Overview
YG Machinery supplies a range of oil and geothermal drilling rigs (hydraulic and thermal models) designed for regional adaptability, heavy-duty projects and digital control. Their equipment has been used in 30+ countries and covers oil & gas exploration, geothermal drilling, coal bed methane, production well construction and mineral exploration.

Key features and capabilities

• Regional adaptation for varied ground conditions: clay, sandstone, bedrock, high-temperature environments and remote sites (off-road tire configurations for remote locations).
• Advanced digital control: PLC control and PROFINET networking for digital drilling to reduce operational errors and increase efficiency.
• Model families: YG-BZT series (1000–1500 m) and YG-ZJ series (YG-ZJ30, YG-ZJ40, YG-ZJ50) covering a wide range of depths and configurations.
• Hydraulic and thermal (geothermal) rig variants available; customization possible by project type (oil exploration, geothermal, mining core sampling, production wells, coal bed methane).
