Man portable water well drilling rig-drills up to 70 meters.
have offered, through this project, the lightest, the most
portable, most flexible and cheepest water well drilling rig
for the world market today. The ultralight water well
drilling “ ALSTEPAN” rig 80m is used for drilling (30…80 m
deep) water wells, having small diameters (Ш 230 mm
borehole), which can be cased with plastic tubes of small
diameters (Ш 110x5,4 - 180x 6,5 mm) being glued or screwed.
The exploitation of the water wells is done with a new
generation of electric water pumps (submersible pumps having
small diameters (Ш100mm) or surface types having Venturi
down to hole ejector tube). The water drilling rig is
offered for a large market made of small land owners, small
entrepreneurs, small business enterprises, small farmers
etc., and it has a huge market succes in Ukraine and also in
European Union and world, because it has the best
price/quality ratio for water well drilling.
The rig uses the classical method of drilling known as: Mud Rotary Drilling, with direct circulation of the mud drilling fluid. The powerhead engine turns the drill stem which has a Drill Bit screwed into end. As the Drill Bit drills down into Earth, the mud Pump recirculates a drilling fluid down the drill stem and out the drill bit. This drilling fluid is pushed up the borehole and flows into a mud pit. After the cuttings (soil, sand, clay) flow into the mud pit, the heavier cuttings settles out of the drilling fluid and the Mud Pump pumps the drilling fluid back down into the bore-hole to repeat this process. The Mud Rotary drilling method of drilling is very common and is the same method that the oil drilling rigs uses.
The drilling line (drilling stems and drilling bit) is rotational driven from a small gasoline engine (four strokes, vertical shaft, power=6 Hp). The drilling head contains also a centrifugal clutch for in-load starting (also acting as safety device and as a uncupling device for isolating the drill stem from tha engine during the screwing, un-screwing the drilling pipes) , a heavy-duty planetary gearhead, the heavy-duty bearings of the drilling head, power swivel for pushing the drilling fluid in the drilling line while it is rotating, the acceleration command device of the engine
The maneuvering (raising and lowering with a drill pitch) of the drilling line is done from a manual ratchet drawwork through the maneuvering system (mobile pulley type) with consist of a crown block sheave and a traveling block sheave. The drilling head is guided on the both front mast columns, the third back mast column is sustained the drawwork. The pushing of the drilling bit is done by the weight of the drilling head and by the supplementary weights hanged from the drilling head. The drilling bits and reamers are covered for hardening through brazing with granules of tungsten (wolfram) carbide. There are also used three blade bits 230mm diameter, armoured with tungsten carbide chips and three cones bits Ш215 mm diameter. After the casing with the WALROM 140x5.4mm PVC Tubes (having collar, thread, oring seal and SCREEN filters with 03-05mmm faints), it is done the de-silting, the clearing and the putting in production of the well, which is done with the MAMOUTH pump (2.5 KW electrocompressor), using the air-lift procedure.
