The actual drilling depth of different air compressor drilling rigs, see what the drilling master says

When the general drilling industry purchases an air compressor, they are more concerned about the drilling depth of the air compressor, but those who sell the air compressor generally do not know the actual drilling depth of the air compressor. Often in order to sell the machine, the boast is particularly powerful. (Compressor colleagues-embarrassed?)

　　1　 Domestic (joint venture) air compressor

　　 There are some differences between the heads produced by foreign companies and those produced by domestic companies. The so-called difference lies in the maintenance of the displacement and the failure rate, but the difference is not too big.

　　 (The following analysis is based on the hardness of the secondary rock)

　　 13/7 piston engine: 13 cm diameter, maximum depth of 70 meters.

　　 15/14.5 twin screw: 15 cm diameter limit depth 129 meters.

　　 18/17 twin screw: 21 cm diameter limit depth 139 meters.

　　 21/13.8 twin screw: 21 cm diameter limit depth 138 meters.

　　27/22 twin screw: 25 cm diameter limit depth 239 meters.

　　26/20 twin screw: 26 cm diameter limit depth 200 meters.

　　In this formula, the basic calculation is the actual efficiency of the kilogram multiplied by 52%. Piston machines can reach 70%.

　　Domestic diesel-driven screw and piston engines:

　　【13/7 Piston Engine】

　　13cm standard caliber, depth 70×0.7=49m

　　【15/14.5 Screw Machine】

　　 15cm standard caliber, depth 139×0.52=72.28m

　　【18/17 screw machine】

　　 21cm standard caliber, depth 159×0.52=82.68m

　　【21/13.8 Screw Machine】

　　 21cm standard caliber, depth 138×0.52=64.86m

　　【27/22 Screw Machine】

　　 25cm standard caliber, depth 239×0.52=124.28m

　　【26/20 screw machine】

　　 26cm standard caliber, depth 200×0.52=104m

　　The actual effect is very much related to the terrain, and the data is limited to the secondary rocks.

　　2 　Imported brand air compressor

　　 (limited to first-line diesel-driven screw machine brands)

　　780﹟: 23.4m3/21.2bar

　　 23.4cm standard caliber, drilling depth 212m.

　　1070﹟: 30.4m3/24bar

　　 30.4cm standard diameter, drilling depth 240m.

　　750﹟: 21.2m3/20.7bar

　　 21.2cm standard diameter, drilling depth 207m.

　　The efficiency of imported machines is higher, which can reach 59% of the actual value.

　　【780﹟】

　　 23.4cm standard caliber, depth 212×0.59=125.08m.

　　【1070﹟】

　　 30.4cm marked caliber, depth 240×0.59=141.6m.

　　【750﹟】

　　 21.2cm standard caliber, depth 207×0.59=122.13m.

　　 Other machines are basically the same, 52% domestically produced and 59% imported. There may be errors between the calculated depth and the actual construction, and there may be some discrepancies with personal drilling techniques, geological conditions, and personal guts. However, the error is not large and can be used as a reference for novices to purchase machines.

　　The dual pressure machines that exist on the market, such as 750﹟ are the conversion of 21.2-20.7 and 24-17.2. That is to say, it is 207×0.59=122.13 meters when the diameter is 21.2, and 172×0.59=101.48 meters when the diameter is 24. That is to say, the larger the diameter, the shallower the depth. The displacement of the air compressor determines the The diameter of the well, kilograms, determines the depth of the well.
