The STD - 135 top drive drilling rig is a low - temperature drilling rig independently developed by our company based on years of R & D, manufacturing, and practical experience in drilling machinery. It is specifically designed for the low - temperature and high - altitude cold regions in Russia. The STD - 135 top drive drilling rig developed this time has a crawler - type walking mode, full - hydraulic drive, top - drive power head, and telescopic mast for its main engine. It is a highly efficient multi - functional drilling rig mainly used for coalbed methane drilling.

This drilling rig is mainly applied in coalbed methane extraction, shallow - layer oil drilling, oil well workover, geothermal water well construction, etc. It can also meet the requirements of ultra - deep core hole exploration in Russia and can be used in engineering rescue, mine ventilation hole construction, and drainage pipeline construction. The STD - 135 top drive drilling rig is equipped with a crane, an operation room, a petroleum mud logging system, a pedestrian ladder, an escape slide, and a hydraulic wellhead baffle, which provides convenience for operators during construction.

The main load - bearing parts of the drilling rig are made of low - temperature - resistant materials, and a heat - preservation and heating system is also designed. It can adapt to a working environment temperature range of - 40°C to + 45°C and a storage temperature range of - 60°C to + 45°C. The drilling rig equipment complies with the requirements of GOST 12.2.141 - 99 and the safety requirements of the oil and gas industry (ПБ 08 - 624 - 03). According to the characteristics of the cold environment, comprehensive customized designs have been carried out on materials, lubrication and sealing, hydraulic transmission, electrical transmission control, etc. The stress - bearing structures of key components all adopt low - temperature - resistant materials, and the lubricating oil tank is equipped with an automatic temperature - controlled heating device.
