IBit Drill Bit / Eccentric Drill Bit
IziXhobo zoKwemba umthwalo ogqithisileyo
Iinkqubo ze-ODEX zeehamile ze-DTH eziyilelwe ngokukodwa ukugrumba kunye necala ngaxeshanye ngomthwalo ogqithisileyo.Ezi zixhobo zokwemba ezinomthwalo ogqithisileyo zidlula ngokulula kumatye amakhulu okutsala ubunzima obukhaphukhaphu apho iikhoseji ezingabizi kakhulu zifakwe emva kwazo.Ezi zixhobo zokwemba umthwalo onzima kulula ukuwususa emngxunyeni/ubunzulu kwaye zinikwa abaxumi bethu kwezi nkcukacha zilandelayo:
1. Ifakwe kwi-drilling apho ukubunjwa kwamatye kunomthwalo onzima kwaye kufuneka ityhubhu ye-casing ukuxhasa.
2. bhetyebhetye ukuvula nokuvala.
3. Uluhlu lwezicelo: Lulungele ukugrunjwa kwamaqula amanzi, amaqula e-geothermal, kunye ne-miscopies emfutshane ephakathi komngxuma wokugrumba wesakhiwo, iprojekthi yedama kunye namazibuko.
4. Imigaqo yoYilo: Yenza i-casing ilandele lula kwaye izixhobo kunye nokusebenza kulula
5. Izinto eziluncedo ezigqwesileyo: Isakhiwo esilula, ukusebenza okulula, umgangatho othembekileyo, izixhobo zokugaya ezibuyiswayo, ubomi benkonzo ende.
6. Iphakheji yangaphakathi eneekhathoni, iphakheji yangaphandle eneemeko zokhuni
