The drilling rig URB 2A2 is designed for drilling wells for various purposes:
✅ drilling of geophysical and structural exploration wells for oil and gas;
✅ exploration of deposits of solid minerals, building materials and groundwater;
✅ engineering and geological surveys;
✅ drilling of water intake and blast wells.

?? Drilling is performed in a rotational manner with flushing or purging of the well, or with augers.

?? A hydraulic rotator moving along the mast is used for drilling, building up the drilling tool without detaching from the face and performs, together with the hydraulic lift, the work of lowering (lifting) the tool and feeding it during drilling. The rotator moves along the mast using a hydraulic cylinder and a hoisting system.

?? The control of the drilling rig is fully hydrofected and concentrated on the driller's console. The control panel contains control devices and regulators for downhole forces, feed and lift speeds, as well as the rotational speed of the rotator spindle.
