[0002] With the expansion of drilling areas, drilling rigs began to operate in some special areas, such as human settlements, wildlife reserves, and natural forest parks. During the use of drilling rigs, a large amount of continuous noise is generated, which has a great impact on the environment around the drilling site. With the development of green environmental protection industry, the environmental protection indicators of oil drilling rigs are becoming more and more stringent, and drilling rig design and manufacturing have begun to consider taking measures to reduce noise.

[0003] At present, domestic oil rigs only deal with noise on a small number of equipment, and most of them use simple wall baffles for noise isolation, such as adopting vertical wall enclosures around diesel generator sets for noise reduction, and adding enclosures on the front side of the winch for noise reduction. There is no device for noise reduction of the entire system. Such noise reduction devices, considering the need for ventilation and heat dissipation of equipment, leave ventilation and heat dissipation areas without noise reduction, resulting in limited noise reduction effect. Now a noise reduction device for oil rigs is designed, which adopts a standard container + enclosure design, and performs overall noise reduction on the three areas of the drilling table, diesel generator set and mud pump group with the loudest noise during the use of the drilling rig, reducing the noise generated by the oil rig during operation, while meeting the ventilation and heat dissipation requirements when the equipment is in use, and meeting the drilling requirements of the rig in special areas such as human settlement areas, wildlife and plant protection areas and nature reserves.
