Introduction of multifunctional coalbed methane drilling rig

The multifunctional coalbed methane drilling rig is a highly efficient device specially developed for coalbed methane resource extraction and various engineering applications. This rig is not only suitable for coalbed methane extraction, but also capable of shallow oil drilling, oil well servicing, geothermal water well construction, and ultra-deep core exploration. Additionally, it can be widely used in emergency engineering, mine ventilation boreholes, and drainage pipeline construction, meeting a wide range of project requirements.

Features of multifunctional coalbed methane drilling rig

• Supports multiple drilling techniques, including coalbed methane horizontal branch drilling, air DTH hammer drilling, high-pressure mud drilling, and gas reverse circulation drilling, adapting to complex geological conditions.
• The main unit adopts a crawler-type walking structure, offering excellent off-road performance and safe access to various terrains, making it ideal for diverse construction environments.
• Dual diesel engine power configuration with hydraulic coupling delivers strong and reliable power. Even if one engine fails, the other can continue operation, ensuring continuous and safe performance.
• Triangular parallel-moving frame design enhances mast stability and wellhead space, facilitating the installation of safety devices.
• Telescopic mast with chain speed-doubling mechanism shortens transport length and increases working stroke, with a simple structure and neat hose arrangement; lifting capacity reaches 90 tons.
• Hydraulic top drive power head provides high starting torque; the floating spindle design facilitates drill rod handling, and the tiltable power head (up to 80 degrees) makes unloading rods easier and reduces labor intensity.
• The hydraulic system uses high-quality domestic and international products, combining closed and open circuits for superior performance, and includes pressure-reducing drilling functions for demanding applications.
• Remote operation system with an independent control cabin keeps operators away from the wellhead, improving safety, comfort, and reducing environmental risks.
• The split-type hydraulic wellhead platform and clamping breakout tong allow for efficient and convenient rod handling via remote electro-hydraulic control, surpassing traditional heavy tongs.
• The main unit is equipped with an onboard crane for on-site lifting of rods and drill bits, reducing operator workload.
• The drilling platform can be optionally equipped with logging systems, ladders, escape slides, and hydraulic wellhead barriers to enhance safety and efficiency.

Applications

This multifunctional coalbed methane drilling rig is widely used for coalbed methane, shale gas, shallow oil and natural gas exploration and extraction, geothermal well and ultra-deep core drilling, emergency engineering, mine ventilation boreholes, drainage pipelines, and other engineering projects, especially in complex terrains and environments with high construction requirements.
