Technical specification
Order of production
A60/80 rig for repair and completion of oil and gas wells, rotary and downhole motors drilling.
Rig mechanisms are mounted on BAZ-690902 or KrAZ-63221.0000044 all-wheel drive chassis .
Conditional depth of well during repair and completion is 4000 meters (drilling is carried out by 14 kg/m tubing ).
Conditional depth of well drilling is 2000 meters (drilling is carried out by 24 kg/m tubing ).
Design characteristics:
- single-drum drawworks or double-drum drawworks with disk pneumatic clutches, that allow to change one range of speed to another one while auxiliary compressor is not required;
- drilling drum with Lebus' grooves that provide even wireline winding;
- extension of upper section by hydraulically driven drawworks;
- hydraulically driven drawworks for auxiliary work;
- oil-filled chain transmission of drawworks drive;
- hydraulic thrusters (outriggers) of both-way action;
- unit completion takes into account unit designation and work technological characteristics.
