Ho cheka oli ea Polyanionic Cellulose

Polyanionic cellulose (PAC) ke tlatsetso ea bohlokoa marong a ho cheka oli, e sebeletsang mesebetsi e fapaneng ho ntlafatsa ts'ebetso ea ho cheka. Mona ke kamoo PAC e kenyang letsoho ho maro a ho cheka oli:

1. Taolo ea Viscosity: PAC e thusa ho laola viscosity ea mokelikeli oa ho cheka, ho etsa bonnete ba hore o na le botenya bo hlokahalang ho jara li-cuttings tse omisitsoeng holimo. Sena se bohlokoa bakeng sa ho boloka botsitso ba seliba le ho thibela litaba tse kang ho putlama ha lesoba.
2. Thibelo ea Tahlehelo ea Mekelikeli: PAC e etsa kuku e tšesaane, e ke keng ea qoelisoa leboteng la borehole, e fokotsang tahlehelo ea mokelikeli sebakeng se potolohileng. Ka ho fokotsa tahlehelo ea mokelikeli, PAC e thusa ho boloka khatello ea hydrostatic, ho thibela tšenyo ea sebopeho, le ho ntlafatsa tlhahiso e ntle.
3. Phetoho ea Rheology: PAC e susumetsa boitšoaro ba ho phalla le thepa ea rheological ea mokelikeli oa ho cheka, e matlafatsa ho fanyeha ha lintho tse tiileng le ho fokotsa ho lula. Sena se tiisa ts'ebetso e tsitsitseng ea mokelikeli oa ho phunya tlas'a maemo a fapaneng a tlase.
4. Lubrication and Friction Reduction: PAC e fana ka lubrication lipakeng tsa khoele ea boro le lebota la seliba, e fokotsa ho hohlana le ho fokotsa ho hula. Sena se thusa ho ntlafatsa ts'ebetso ea ho cheka, ho fokotsa ts'ebetso ea lisebelisoa tsa ho cheka, le ho lelefatsa bophelo ba lisebelisoa.
5. Tlhoekiso e Ntlafetseng ea Likoti: Ka ho eketsa ponahalo le bokhoni ba mokelikeli oa ho cheka, PAC e thusa ho tlosoa ha likheo tse chekiloeng le lithōle tse tsoang selibeng, ho ntlafatsa ts'ebetso ea ho hloekisa mekoti le ho fokotsa kotsi ea liphaephe tse khomaretsoeng.
6. Thempereichara le Botsitso ba Letsoai: PAC e bonts'a mamello e phahameng ea mocheso le letsoai, e boloka ponahalo ea eona le litšoaneleho tsa ts'ebetso holim'a mefuta e mengata ea mocheso le letsoai le fumanoang mesebetsing ea ho cheka.
7. E Sekehela Tikoloho: PAC e nkiloe mehloling e nchafalitsoeng e thehiloeng ho limela 'me e khona ho senyeha, ho e etsa hore e se ke ea silafatsa tikoloho ebile e loketse ho sebelisoa libakeng tse chekoang haholo ke tikoloho.

Ka kakaretso, cellulose ea polyanionic ke karolo ea bohlokoa ea maro a ho cheka oli, ho fana ka viscosification, taolo ea tahlehelo ea mokelikeli, phetoho ea rheology, le lisebelisoa tse ling tsa bohlokoa ho netefatsa ts'ebetso e atlehileng le e atlehileng ea ho cheka indastering ea oli le khase. Ho tšepahala ha eona, ts'ebetso, le ho lumellana ha tikoloho ho etsa hore e be khetho e ratoang bakeng sa ho ntlafatsa ts'ebetso ea mokelikeli oa ho cheka le botsitso ba hantle.
