A7-60M unit is designed for repair of oil and gas wells, (the depth of the well is determined by the capacity of the unit) and allows to carry out the following works:
— moving from well to well
— mounting and dismantling on well
— lifting operations with pumps and compressors, drilling pipes and pumping rods
— the elimination of wells
— drilling out the cement plugs , and related process operations
— millingofmetalobjects
— drilling operations.
The unit allows you to create a short-term load on the hook to 80 tons, in cases of delays, explosion of packers etc.
The unit is designed for use in temperate and cold macro-climatic areas according to GOST 15150-69.
Climatic version of «U» at ambient temperatures from -45 º C to +40 º C.
