Intwana yokutsala inyathelo yintwana yokomba edla ngokuyilelwe ukusetyenziswa kulwakhiwo oluthambileyo njengesanti, udongwe, okanye ilitye elithambileyo.Nangona kunjalo, aziyi kusebenza kakuhle kwigrabile erhabaxa okanye kulwalwa oluqinileyo.Usebenziso lubandakanya ukugrumba amaqula amanzi, imigodi, i-geothermal.esingqongileyo kunye nokwembiwa kokuhlola.Nanini na kunokwenzeka, zifanele zisetyenziselwe ukugrumba imingxuma yokuqhuba kuba zivelisa amagatya ekulula ukuwagalela.
I-3 amaphiko inyathelo lokutsala amasuntswana sisixhobo esinye sokwakhiwa kwentsimbi yealloy kunye neengcebiso zokusika i-tungsten carbide kunye namacala okulinganisa ukuqinisekisa ubomi obude.Inamaphiko ama-3 kunye nemingxuma emi-3 egungxulwayo.Xa kuthelekiswa namaphiko ama-4, amaphiko ama-3 amasuntswana okutsalwa athanda ukubhola ngokukhawuleza kwaye abe ndlongondlongo, kanti, amfutshane kwaye ahlala ixesha elide. Amaphiko angama-3 enyathelo lokutsala amasuntswana aya kuvelisa amandla amakhulu okusika kune-chevron style drag bit.Isantya setafile esijikelezayo semilinganiselo yokutsala kufuneka sibe phakathi kwama-60 kunye nama-80 rpm ngobunzima obulula kwibit (WOB).
3 amaphiko inyathelo utsalo amasuntswana zixhobo zoqoqosho xa kusombiwa ukwakheka ethambileyo zejoloji kunye nobunzulu obunzulu, ziyilwe ngokuyintloko kulwakhiwo oluthambileyo oluphakathi, olufana nodongwe, oluvunduvundu, lwentlenga, umhlaba omninzi-ukuya-phakathi onokufuma, njl. kucetyiswa ukugrunjwa kwiMining, ukuPhonononga, iNdalo, iqula lamanzi, iGeo Exchange, njl.
Qaphela: I-diameter kunye nentambo eboniswe ngasentla zibukhulu besiqhelo, ezinye iisayizi ziyafumaneka xa ziceliwe.
