Idizayinelwe ngokukhethekile ukwehlisa i-coefficient of friction kukho konke uketshezi lokumba olusuka emanzini, okwehlisa i-torque nokudonsa emgodini womthombo.Ngesici esiyingqayizivele sokumanzisa esehlisa amandla okubhola kwe-Bottom-Hole Assembly (BHA), ayinawo ama-hydrocarbons futhi ihambisana nawo wonke uketshezi olusuka emanzini, okuhlanganisa uketshezi lwe-brine oluyi-mono-/divalent.Ngomnikelo omncane ezicini ze-rheological zezinhlelo zodaka, ayifaki igwebu futhi ingangezwa ohlelweni lodaka ngokusebenzisa i-hopper yokuxuba noma ngokuqondile ohlelweni olungaphezulu nomaphi lapho kutholakala khona ukuphazamiseka okuhle.
7-Izinzuzo
1. Isithambisi esisebenzayo, senhloso yonke sezinhlelo zodaka ezisekelwe emanzini
2. Nciphisa i-coefficient of friction enciphisa i-torque nokudonsa
3. Ayikhulisi i-rheology noma amandla ejeli
4. Iqukethe izithasiselo zokumanzisa insimbi ezihlukile ezinciphisa ukuthambekela kwe-shale ethambile, enamathelayo ukuze ibangele ukubhola kancane kanye ne-BHA.
5. Ayibangeli ukukhihliza amagwebu
6. I-biodegradable engenawo ama-hydrocarbon
7. Ukumelana nezinga lokushisa ≤200℃ (BHCT)
