The STD-65 crawler - type multi - functional coalbed methane drilling rig is a new type of multi - functional coalbed methane drilling rig newly developed by our company. It is based on the characteristics of domestic coalbed methane exploration and exploitation, combined with the advanced experience and concepts of foreign coalbed methane exploitation, and drawing on the advanced technologies of similar drilling rigs at home and abroad. Compared with foreign drilling rigs, it has a simple structure, excellent performance, and good cost - performance, making it a coalbed methane drilling rig more suitable for China's national conditions. This drilling rig is mainly applied to coalbed methane exploitation, shallow - oil drilling, oil well workover, geothermal water well construction, and can also meet the requirements of survey drilling for ultra - deep core holes in China. It can also be used in engineering rescue, mine ventilation hole construction, and drainage pipeline construction.

The STD-65 crawler - type multi - functional coalbed methane drilling rig adopts full hydraulic drive, top - drive power head, telescopic mast, and crawler - type self - propelled travel structure. It is a multi - functional and efficient drilling rig mainly for coalbed methane drilling. This drilling rig can be constructed by various methods such as air hammer impact drilling, gas reverse - circulation drilling, and high - pressure mud drilling, meeting the diverse construction requirements under a variety of different geological conditions.
