A special vehicle for blowout prevention and workover equipment

technical field

The utility model relates to a special vehicle for blowout prevention well workover equipment, in particular for oil field workover equipment, and belongs to the field of petroleum mechanical equipment.

Background technique

Blowout-proof workover equipment is a new type of workover equipment that does not “spill out”. The use of equipment can avoid the pollution of the environment around the oil field and the waste of water resources, and improve the production efficiency of the oil field. The equipment has been popularized and used in China.
