Product Introduction:
This drilling rig is a land drilling rig with a maximum drilling depth capacity of 7000m, mainly used for oil and gas exploration and development at depths of 4500-7000m (drill pipe 4 1/2 ") or 4000-6000m (drill pipe 5");
The basic parameters, structural types, and design and manufacturing of the drilling rig comply with international standards such as API, IEC, HSE, etc;
The design and selection of various systems and equipment for drilling rigs often use high-temperature resistant components and air-cooled cooling methods, enabling the drilling rig to adapt to harsh environments such as high temperatures, deserts, and heavy rain.
