URB-3A3 mobile drilling rigs
ENG RUS
Mobile drilling rigs URB-3A3 are used for rotary drilling of oil-,
gas cored wells, for drilling water-wells for agriculture and industry, for
water depression with direct flushing of bottomhole in soft and medium-hard
rocks. Rotary rigs are a version of a set of unified mobile rigs of БА15 type;
they have YaMZ-236 (3A3.02.13 drilling rig) or YaMZ-238 (3A3.051drilling rig)
stand-alone deck diesel engine.
URB-3A3.02 drilling rig
Major
equipment of URB-3A3.02 drilling rig:
- drilling block (rotary table
Р410, double-drum draw works, 18,6 m mast, НБ50 mud pump, generator, swivel,
manifold) on МАZ-5337 chassis;
- mud mixer, working floor, kelly, drilling
and pipe handling tool.
URB-3A3.13 drilling rig
URB-3A3.13
drilling rig is mounted on off-road URAL-4320-1912-30 chassis and has all the
design features of URB-3A3.02 drilling rig. The difference is YAMZ-236
stand-alone diesel engine with a gearbox and pneumatic system for facilitating
the rotary rig control.
URB-3A3.051 drilling rig
Major equipment
of URB-3A3.051 drilling rig:
- drilling block (РК410 rotary table,
double-drum draw works, 10,0 m mast, two НБ50 mud pumps, generator, swivel,
manifold) on ОЗТП-8470 tractor trailer chassis;
- mud mixer, working floor,
kelly, drilling and pipe handling tool.
Upon the customer's request we
supply the following:
- pumping power plant НП15А with the pump of НБ125
type on MAZ-8925 truck-trailer;
- БА15-71сб compressed-air unit on MAZ-8925
truck-trailer for transportation of up to 6 m drill pipes;
- monkey board,
racking board, hydromixer instead of mud mixer, hydraulic feed unit, single-drum
draw works, 19,7 m mast, hydraulic breaker.
The advantages of
URB-3A3.02, URB-3A3.13, URB-3A3.051 drilling rigs:
- pneumatic control
of the major units (URB-3A3.13, 051). It increases efficiency and decreases
lever force. Manual backup ensures high reliability of rig control;
- due to
wide speed range on the draw works and rotary table, drilling technique can be
selected easily;
- mechanical means make the work comfortable, increase
safety, facilitate odd jobs and reconditioning, decrease the time required to
perform the before mentioned jobs (hydraulic mounting of the rig frame, breakout
device, hoisting device for reconditioning, device for air-purging of drill
hose, etc.).
URB-3A3 drilling rigs are highly effective, simple to use,
reliable, easy to handle and maintain.
