1. Isifinyezo
I-OBF-NIS, inhlanganisela yezinto zefayibha nezinto eziqinile, inokugcwalisa kahle, ibhuloho kanye nemiphumela yokuvimba.
I-OBF-NIS inomphumela omncane ekulahlekeni kwamanzi amile kanye ne-rheology yoketshezi lokumba, iqinisekisa ukuzinza kokusebenza koketshezi lokumba.
I-OBF-NIS, ingadlula ngempumelelo iso lamanzi le-drill bit kanye nesikrini esidlidlizayo, ukuze ukubhola nokuxhuma kuvumelaniswe.
I-OBF-NIS ingathuthukisa ngempumelelo ikhwalithi yekhekhe lokuhlunga futhi yehlise ukulahleka kwesihlungi esijikelezayo soketshezi lokumba.
2.Idatha yobuchwepheshe
| Into | Inkomba |
| Ukubukeka | Impushana eqinile egelezayo yamahhala |
| Umswakama | ≤8% |
| Izinsalela zesikrini (ubude obuseceleni bembobo yesisefo ngu-0.15mm) | ≤10% |
| Ukujula kokungena kombhede wesihlabathi | ≤8cm |
3.Ibanga lokusetshenziswa
Emanzini okumba amanzi ahlanzekile nasolwandle.
Umthamo ophakanyisiwe: 1.0–3.0% (BWOC).
4. Iphakheji
Ipakishwe isaka lephepha elingu-25kg elinefilimu yepulasitiki engangeni manzi ngaphakathi.Noma ngokusekelwe esicelweni samakhasimende.
Impilo yeshelufu: izinyanga ezingama-24.
