PAC-LV, PAC-Hv, PAC R, Lisebelisoa tsa ho Cheka Oli

Polyanionic cellulose (PAC) e atisa ho aroloa ka lihlopha tse fapaneng ho latela boima ba limolek'hule, tekanyo ea ho fetola, le lisebelisoa tse ling. Mona ke karohano ea mefuta e meng e tloaelehileng ea PAC e sebelisoang indastering ea ho cheka oli:

1. PAC-LV (Viscosity e tlase):
   • PAC-LV ke tekanyo e tlase ea viscosity ea cellulose ea polyanionic e sebelisoang marong a ho cheka a thehiloeng metsing.
   • E tsebahala ka viscosity ea eona e batlang e le tlase ha e bapisoa le limaraka tse ling tsa PAC.
   • PAC-LV hangata e sebelisoa ha taolo e itekanetseng ea viscosity le taolo ea tahlehelo ea mokelikeli e hlokahalang ts'ebetsong ea ho cheka.
2. PAC-HV (Viscosity e Phahameng):
   • PAC-HV ke boemo bo phahameng ba viscosity ea selulose ea polyanionic e sebelisetsoang ho fumana viscosity e phahameng ho maro a ho cheka a thehiloeng metsing.
   • E fana ka thepa e babatsehang ea rheological le taolo ea tahlehelo ea mokelikeli, e etsa hore e tšoanele maemo a thata a ho cheka moo ho emisoa ho eketsehileng ha lintho tse tiileng ho hlokahalang.
3. PAC R (Kamehla):
   • PAC R, kapa PAC ea boemo bo tloaelehileng, ke sehlopha sa viscosity sa mahareng sa polyanionic cellulose.
   • E fana ka li-viscosifying tse leka-lekaneng le thepa ea ho laola tahlehelo ea mokelikeli, e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea ho cheka lits'ebetso moo ho hlokahalang viscosity e itekanetseng le taolo ea tahlehelo ea mokelikeli.

Likarolo tsena tse fapaneng tsa PAC li sebelisoa mekelikeli ea ho cheka oli ho fihlela sepheo se ikhethileng sa viscosity, rheology, le taolo ea tahlehelo ea mokelikeli ho ipapisitsoe le maemo a ho cheka, litšobotsi tsa sebopeho, le litlhoko tsa botsitso ba seliba.

Ts'ebetsong ea ho cheka oli, PAC e sebelisoa e le tlatsetso ea bohlokoa marong a ho cheka a thehiloeng metsing ho:

• Laola viscosity le rheology ho ntlafatsa ts'ebetso ea ho cheka le ho thibela ho se tsitse ha wellbore.
• Fokotsa tahlehelo ea mokelikeli sebopeho, ho fokotsa tšenyo ea sebopeho le ho ntlafatsa tlhahiso ea hantle.
• Emisa li-cuttings tse chekiloeng le tse tiileng, ho thusa ho tlosoa ha tsona selibeng.
• Fana ka lubrication le ho fokotsa khohlano lipakeng tsa khoele ea boro le lebota la seliba.

Ka kakaretso, PAC e bapala karolo ea bohlokoa e le sesebelisoa sa viscosifier le se laolang tahlehelo ea mokelikeli marong a chekang a thehiloeng metsing, e kenyang letsoho ts'ebetsong e atlehileng le e atlehileng ea ho cheka indastering ea oli le khase.
