Umbhobho wokubhobhoza wenziwa ngokudityaniswa kweziqwenga ezithathu ezihlukeneyo: isixhobo sebhokisi esidityanisiweyo, isixhobo sesixhobo sephini kunye nombhobho.Iziphelo zeetyhubhu ke ziphazamisekile ukwandisa indawo enqamlezileyo yeziphelo.Isiphelo sombhobho sinokuphazamiseka ngaphandle (EU), ukuphazamiseka kwangaphakathi (IU), okanye ukuphazamiseka kwangaphakathi nangaphandle (IEU).Imilinganiselo yokuphazamiseka okuphezulu okusemgangathweni ichazwe kwi-API 5DP, kodwa imilinganiselo yokuphazamiseka ilawulwa ngumenzi.Emva kokuphazamiseka, ityhubhu emva koko ihamba ngenkqubo yokunyanga ukushisa.Intsimbi ye-Drill pipe idla ngokucinywa kwaye inomsindo ukuphumeza amandla aphezulu esivuno
Umbhobho we-Drill luhlobo lweetyhubhu zentsimbi ezinomsila ophothiweyo, ngokukodwa osetyenziselwa ukudibanisa izixhobo ezingaphezulu ze-drilling rig kunye nokugaya kunye nezixhobo zokusila okanye isixhobo somngxuma osezantsi ezantsi kwe-drilling.Injongo yombhobho wokugrumba kukuthutha udaka lokwemba kwi-bit kunye nokunyusa, ukuthoba okanye ukujikelezisa isixhobo somngxuma osezantsi kunye nebit.Umbhobho we-drill kufuneka ukwazi ukumelana noxinzelelo olukhulu lwangaphakathi nangaphandle, ukujija, ukugoba kunye nokungcangcazela.Kwinkqubo yokukhutshwa kweoli kunye negesi, umbhobho wokubhobhoza ungasetyenziselwa amaxesha amaninzi.Umbhobho Drill na ingaba bo yahlulwe zibe ntlobo ezintathu: Kelly, umbhobho drill kunye neweighted umbhobho
