Amapangidwa makamaka kuti achepetse kugundana kwamadzi onse obowola m'madzi, omwe amatsitsa torque ndikukokera pachitsime.Ndi chikhalidwe chapadera chonyowa chomwe chimachepetsa kuthekera kwa mpira wa Bottom-Hole Assembly (BHA), ilibe ma hydrocarboni ndipo imagwirizana ndi madzi onse amadzi, kuphatikizapo mono-/divalent brine fluids.Pokhala ndi chothandizira chochepa ku machitidwe a rheological a machitidwe a matope, sachita thovu ndipo akhoza kuwonjezeredwa ku dongosolo lamatope kudzera muzitsulo zosakaniza kapena mwachindunji kumtunda wapansi kulikonse kumene kusokonezeka kwabwino kulipo.
7-Ubwino
1. Mafuta ogwira mtima, opangira zonse pamakina amatope amadzi
2. Chepetsani kukokana komwe kumachepetsa torque ndi kukoka
3. Simawonjezera mphamvu za rheology kapena gel
4. Lili ndi zinthu zina zapadera zonyowetsa zitsulo zomwe zimachepetsa chizolowezi cha shale yofewa, yomata kuti ipangitse bilu ndi BHA.
5. Sichimayambitsa thovu
6. Zowonongeka popanda ma hydrocarbons
7. Kusamva kutentha ≤200 ℃ (BHCT)
