Yenzelwe ngokukodwa ukucutha i-coefficient of friction kuwo onke ama-water-base-drilling fluids, ehlisa i-torque kunye nokutsala kwiqula.Ngophawu olulodwa lokumanzisa oluthoba amandla ebhola e-Bottom-Hole Assembly (BHA), ayinayo i-hydrocarbons kwaye iyahambelana nawo onke ama-water-base fluids, kuquka i-mono-/divalent brine fluids.Ngegalelo elincinci kwiipropathi ze-rheological zeenkqubo zodaka, ayifaki ugwebu kwaye inokongezwa kwinkqubo yodaka ngokusebenzisa i-hopper yokuxuba okanye ngokuthe ngqo kwinkqubo yomphezulu naphi na apho kukho ukuphazamiseka okulungileyo.
7-Izinto eziluncedo
1. I-lubricant esebenzayo, yonke injongo yeenkqubo zodaka ezisekelwe emanzini
2. Nciphisa i-coefficient of friction enciphisa i-torque kunye ne-drag
3. Ayinyusi i-rheology okanye amandla e-gel
4. Inezongezo zokumanzisa isinyithi ezizodwa ezinciphisa utyekelo lwe-shale ethambileyo, encangathi ebangela ukuba i-bit kunye ne-BHA balling.
5. Ayibangeli ugwebu
6. I-Biodegradable ngaphandle kwee-hydrocarbons
7. Ukumelana nobushushu ≤200℃ (BHCT)
